Given the increasing reports of D800 owners receiving cameras that have autofocus problems, I'd like to get a sense of just how widespread the issue is (at least amongst our population of users). The issue, as you're probably well aware, is AF points in the viewfinder to the left of center lock focus when out of focus. Essentially, autofocus using the left-side AF points is inaccurate leading to out-of-focus images.

Nikon now claims 'a run' of cameras are affected, but it's unclear how many this may include.

It may also be helpful if you include your camera's serial number with your posted response to help users narrow the range of affected cameras.

Focus is working fine so far. In fact, no malfunctions at all so far.

All joy to date.

No problems to date. I have not used my 14-24 however. The 24-70 and 70-200 VR II are great. The Sigma 150-500 does not make me giggle at 500mm. I haven't had as much time as I would like to explore the new boundaries.

D800 serial number 30076xx.

I've not tried any tripod tests of the left side AF points, but I did a few hand held shots using many of the left side points and did not see any focus problems.

Unfortunately, I discovered that my D800E does, in fact, exhibit a severe out of focus result with the left AF points. I didn't notice it at first, but I was rather puzzled with some out of focus shots. After getting emails from my Nikonian buddies, I specifically checked and sadly, my camera has now been shipped back to Nikon in Toronto for a hoped for recalibration.

While I am disappointed, I must say that I agree with those that say the camera is a "game changer" ... especially in concert with Adobe's latest Camera Raw software. The effective dynamic range is hard to believe and I find the camera a joy to use.

I apologise for giving you a wrong answer. Change me to the yes group. After thinking about it, I went out in the yard and took center and left focus point photos using the 70-200 VR II at 70mm, 24-70 at 24mm, and 14-24 at 14mm. It was all down and dirty, hand held, iso 100, at 2.8. The 70-200 and 24-70 at about 10 feet, the 14-24 at about 4 feet. I was shooting a section of old fence for the grain in the wood. I compared each pair of photos and found I do have a problem. The 70-200 has no noticeable focus problem on the computer monitor at 100%. I get slightly out of focus shots with the 24-70 and bad out of focus with the 14-24 when using the left side focus point.

Big disappointment. The question is, do I send it back to Nikon now and beat the rush or wait a bit until they have time to figure it out and come up with a permanent fix?

No focus problems with mine. So happy I have not had any problem worth mentioning with the D800. Where I live there is no Nikon service so whenever I buy a brand new product I am pretty much hoping for the best. Sending my camera overseas for half a year would not make me happy. (Credit to Nikon, I don't think I would have had the guts to be a early buyer with an other camera brand.)

I've been doing the same experimentation with those same two lenses, and what I've found is if I shoot a LOT of shots, I get more shots with poor focus on the left. But I also get most shots dead on.

Did you shoot only one of each, or a couple? Shoot a bunch. Start with it very out of focus each time. And check if you have focus priority set to Focus instead of Release or Release+focus.

I don't propose there is no problem, but what I'm seeing is more a decrease in consistency than a consistent out of focus.

I got my D800 last week and my LensAlign confirms that the left side sensors back focus (not that I needed the LensAlign as the problem is obvious). My serial is 3006654. I'm going to send it to Nikon for some TLC.

I also noticed that it is off with all lenses -not just fast wide angles. It's just that the degree of error varies so it's less obvious with some lenses.

Mine is a touch soft on the left side. I probably would never have noticed if I didn't read about the issue online though. 30072XX

Since returning it and getting another is out of the question since it'll be a 3+ month wait and the next one may have the same issue, I've called Nikon USA. As above, they requested sample images that I'm working on sending them.

Chuck, are you in Roseville California? If so, take to the authorized warranty station on 28th street in Sacramento: California Precision Service. They have a good rep with Nikon owners and are pretty fast.
Their phone number is 916-451-1330
Ask them if they have the new revised focus calibration procedures for the D800.

Stan, thank you very much. The Nikon tech support guy was not very helpful. I have done business with CPS before but mainly for cleaning. I will give them a call. I didn't realize they could do the calibration.

Stan, I just called CPS. They are aware of the problem but Nikon has not "officially notified" them or sent them the calibration materials/software. They were very sympathetic but there is nothing they can do.

I haven't heard back from Nikon on the two samples I sent them either. Of course it has only been one business day.

Camera arrived today and shows no sign of any left side focus problems. I didn't take any wide angle shots but I did put the 24 1.4 on and did a focus check through the viewfinder and everything looked fine. I suppose I could have taken shots at 24 and pixel peeped, but why put a damper on a great day.

Unfortunately, I too have the Auto Focus issue with the left focus points, serial number 30006xx. I performed my test shots using a 24-70mm lens @24mm f2.8 from a distance of 1-2 yards. Live View is fine – Left AF points are severely back focusing. Can recreate very easily hand-held as well as on a tripod.

I have not done a lot of shooting with the D800 yet, but going from a D200 I’m blown away by the dynamic range of the color and the detail, all I can say is WOW! I’ve shot a few lacrosse games and as with my previous camera I’ve had hit or miss issues with the focus. I’m hoping once I get the focus system calibrated by Nikon the number of keepers will rise.

Looking at Nikon’s website it does not look like there are any Authorized Repair Stations near the DC area so I will need to mail my camera away. I’ve tagged the Auto Focus topics and am anxiously awaiting news of service centers being geared up to handle the issue. I’ve never had to send a camera to Nikon, I assume the shipping TO them is on me, and the return shipping is on them.

I appreciate the efforts of all the Nikonian’s in documenting the issue and helping me along. I’ve been mostly a lurker on and off for years and the information I’ve gleaned for everyone’s posts has made me a better photographer.

Regards,

CJ

I wanted to add some info under which conditions this issue mostly appears:

- Wide Angle to short telephoto lens (I saw it with 14-24, 24-70, 24, 35, 85mm lenses and 70-200 at 70mm, but not with 105, 135, 70-200 at 200mm lenses etc)

- Fast apertures (f/2.8 or faster). With slower lenses, the DOF will often cover the misfocus

- Subject distances longer than 10ft. I don't know why this is, but I saw the issue mostly with longer distances.

- Left-most focus point. Other points may be affected but to a lesser degree.

The issue can also be seen when only some of these conditions are met, but it is most obvious when all 4 are met. I have seen the same issue with 3 bodies so far (all D800).

Did some controlled tests following Tom's criterion with the 24 1.4 and sad to say my D800 does has left side focus issues. Now deciding whether to send back to the merchant or hold on and send to Nikon later.

Just curious, have you tried a quick test matching the 4 criteria with your D700?

Keep it! Why wait months for another camera? It's a minor issue and sending it to Nikon only costs you ~$50 and a week or two without it. I'm holding onto mine and waiting while Nikon reviews my images. After a big event in June, I'm going to send her in. She'll be perfect in no time. This really isn't a huge issue unless you focus track using these other focus points. Otherwise, I focus with the central point and recompose...problem solved.

Sure, that was the first thing after I encountered the issue. The D700 focuses fine under these conditions.

Also, here is another update: The dealer where I returned one of the cameras had it tested by a Nikon tech, got this email:

...reason is because our Nikon Rep and a certified Nikon Tech is going to be here to talk to me and the product manager…since they will be here and your camera came just intime they want to try and recreate the defect..to make sure it is defective… Not that we don’t believe you...

Then the next day I got this email:

Thank you, for the input on the focusing point I showed it to them and your right.. its being delivered back to nikon and the Rep and the Tech is keeping your info to watch for anymore…

So Nikon is becoming aware of the issue. I hope they will get it fixed soon in the production line.

Steve,

I tested my D700 (Remembering the Banding issue when pretty much an sensor will show some banding under extreme conditions). My D700 no better than my second D800 which I consider to have a slight focus error in extreme left focus point pretty much under the conditions Tom outlined. Tested it at 12 feet with the 24 1.4 at 1.4. Using the left most focus point, the image was not as well focused as the same image if I lock focus with the center point and recompose to frame the target in the same place in the frame. But then, neither was my D700. It's hard to say which is worse because there are so many more pixels on the same size image with the D800. Of course, I was shooting with a tripod and at a shutter speed high enough that I would normally handhold.

My feeling (not as strong as a conclusion because I don't have inclination to do more rigerous testing) is that my second D800 is withing acceptable limits. I probably would never have suspected it was slightly off if I had not first used one from the bad run.

Edited to add: My testing was not rigerous enough to see the problem with the 85 1.4. In other words, if there is a focus error it is so small I don't care.

I comment on Tom's excellent analysis of the left focus point issue: With exception of it being primarily wide angle the conditions under which it occurs are simply narrow DOF.

My first D800 was so far out that you could see it by chimping the image. Still, it took me several days to realize something was wrong. I don't shoot narrow DOF with wide lenses very often. I did realize I was missing a larger number of shots than usual and was wondering at my fundumentals. I actually started to consider there was some substance to all the hyperbola about needing a tripod for every shot.

That's the way I am leaning. It has no consequence for macro since I'll be at least 105mm, probably manual or Live View and small aperture. Just wish Nikon would put out some type of statement. Given Tom's post below (#25), the situation is still unfolding.

According to a couple reports, Nikon Japan has established a revised calibration procedure for repair shops. It appears that either the alignment jigs or software used in alignment, procedures in alignment or a combination of these elements is being blamed. That would make sense since a number of people have reported their d800's were able to meet spec after re-calibration.
I doubt there is a design or mechanical problem involved but it means those with the problem are going to have to send or take their camera to an authorized service center for the adjustment. Firmware is not likely to have any impact on the problem.
I pick up mine day after tomorrow and will test it immediately because I am leaving the country for 4 months 2 days later. I would be able to live with it however is it only pertains to far left side FPs.
A few people sent their cameras earlier might have gotten a repeat of the calibration procedure that was the same as what caused the misalignment at the factory in the first place

Unless it's a software/firmware fixable item, I doubt they'll say anything and just quietly fix the production line for future copies. The last thing Nikon wants is 1000s of early D800 getting sent in because they acknowledge the problem. I'd guess Nikon would rather deal with the people who notice and hope the rest never figure out there is an issue.

When I called Nikon USA, I got the Coolpix line by accident first. I said I had an AF issue with my D800 and asked it was a known issue. The woman said "yes it is, but this is the Coolpix line." Then I called the DSLR line and asked the same question and the woman there claimed that they haven't heard of any such issues. Either the first woman let the cat out of the bag or the second one didn't know anything.

OK thanks guys. It sounds real then. I will plan to test my D4, but I hadn't detected any problems in real life usage. However, for whatever reason I have done a ton of right-side AF point shooting but very little left-side and pretty much all my shooting so far has been telephoto too.

Deja vu all over again. This reminds me of the issue with the 70-200 VR II and what looked like metal filings inside. One of mine had it, one did not. It took Nikon a while to issue a formal statement. They tap danced for a bit but finally took mine in for repair. I believe this is taking longer though.

Hi Chuck
I just got back from picking up my D90 for AF calibration. The camera looked like new and all I have tested on the D7000 is back to the way it was, very good.
I asked them about the status of the calibration, whether there was a service notice about the D800 calibration procedure. I was told they could not do it until their techs got training on at Nikon. He said there was no firm date when they would get the certification but they will have it. This is the same procedure for all new bodies.

Mine seems to have the issue.
I took a photo of a wooden wall and the center and right side were sharp but the left side clearly not.

When I contacted the Niskon support in Finland and sent them the photo, they did not accept the issue because the lense was the Sigma 24-70 and not a Nikkor. They would only accept photos with Nikkor lenses. So I had to change the Sigma for a 2x more expensive Nikkor, which works better.

After much practice and trying different settings, I still get most photos out of focus even at high speeds and with a tripod.
Still they don´t want to do anything about the problem. I sent them links to forums posts and their view is that forums exaggerate and are not reliable.

They don´t belive me because I am the only person in Finland who has reported a problem with the D800. That is a silly reason for not believing and expecting more complaints: as far I my D800 is the first and only delivered to Finland. How could there be more complaints???!!!
And then they closed my ticked...

So I have to wait till Nikon admits the issue and communicates the solution and as long carry 2 bodies and if I don´t get a sharp shot with the D800 then shoot it again with the D200 =(

Nikom is probably hearing a lot of phones ringing about now. CPS, as I mentioned above, can't do them until they send a tech to Nikon for training or arrange for a Nikon trainer to come to Sacramento.
That makes sense.
I am going to get mine early Sunday and will check it out but will assume it has a problem so I will be pleasantly surprised if it doesn't. I can get by without the outer left FP, so will wait until I am back in the country in September to have it adjusted. If it does or doesn't have the misalignment, I will still be happy getting it. It is not as if my income depended on having good focus accuracy on the left outside FP

Did you say left "OutSide" focal point?
That is OutSide my usual range, but it works anyway.

You should check your batteries before you return to St Petersburg.
Most of the bad ones came with D800s.
I heard that Best Buys will exchange over the counter.

Hi Roger,
I guess I could have been more specific, about it not being left out of doors but "leftmost FP". From most of the reports, the furthest to the left side focal point is the main one impacted by the improper calibration at the factory. On the FX distribution pattern, it would be used more than on a DX pattern because the FX pattern is clustered together in a tighter group in the center of the frame.

Yes, the battery notice, we all got due to having registered a camera that uses that model battery, was copied and and saved as a pdf to make sure the one supplied with the D800 is not of the same lot number. I keep a couple spare batteries for the D7000 so I am covered in case the store can't exchange it right away. I leave on Tuesday morning for Scotland so there would be no time for the Nikon exchange program.

I'm sorry to hear that you're having trouble with your local Nikon support office. I don't know who the repair facility is for Finland, but if it's a pan-European one, they probably have the new calibration solution in place by now. It may be worth pressing them with more calls and test results (perhaps use a 50mm 1.8 wide open). I suspect that if you persist they will relent.

However, if you have the time to re-take a shot, I think you have the time to either manually focus or use the live view screen zoomed in to focus. My understanding is that the problem affects only the phase detect autofocus module and so live view will produce better results.

If you guys are having softness issues on the left side (and even if you're not), I strongly suggest you try Topaz InFocus. It's available as a free-trial and does deconvolution. In the Generic and Estimate Blur settings, I've found it makes the out-of-focus issue disappear (and I mean, razor sharp). If you bump up the Reduce Artifacts to max, it does a darn good job. Definitely a program to buy once you've sampled it.

While I'd still rather have mine adjusted, I don't have to worry about lost photos. Seriously, try the program.

Examples below. You can either apply to the entire image or create a mask in PS and just apply to your focus point area.

Does your camera focus well using the central or right side FPs? How much of your work depends on the far left focal point?
Don't bother referring them to forums, most are not very trustworthy posts so they have learned the hard way to ignore claims and go by evidence. Set your camera on a tripod and use good technique to reduce the number of variables(mirror up, VR off, remote trigger etc) and take a reference shot in Live View and a series starting from one side of the FP array and take multiple shots using each FP. Send them a listing of test conditions and give meaningful names to each frame and send the array of images and explanation.
It is better not to guess the cause, techs are inclined not to believe people as much if they make a claim about cause because history shows that they are usually wrong. Tell and show them your evidence and let them make a diagnosis. Some shops have gotten the correct information, such as the one in the Netherlands but most do not have any clue about the problem yet.
Good luck

I called Nikon on Saturday about my focus problems. The woman I spoke to cut me off mid sentence saying she knew about the problem. She said she would send an email with instructions on how to submit pictures of the AF problem and that Nikon will evaluate them and we'll proceed from there. I sent them nine pictures. I guess we'll see what happens next.

I purchased my D800 last week in the UK Serial number starts in the 601XXXX.

Contacted Nikon support who just said I had to send in test shots. The guy seemed like he knew what the issue was but didn't want to let on.

I did the same test like you. The centre AF give the shapest image, followed by right AF and then left AF. I did contact my local Nikon SC, they ask for test samples for checking and verification. Haven't not decided to send to my local Nikon SC until they have concrete solution to the issue. For the moment, the camera is still giving good result using centre AF.

Nikon Australia have decided that they will give me a new camera... I didn't ask for this. I am hoping my new one doesn't have the issues my current one has. But even clearly being one of the run of 'bad' ones its still a great camera, you just need to work a bit harder at it and be more precise. Kinda like shooting film The rewards are there for the taking.

You guys have worried me so much about this AF deal I decided to retest mine. Left focus perfect. Right focus perfect. Center focus perfect and that's with my 85mm 1.8G. Which I think is the sharpest lens I own right now.

At this point, I'm curious why a serial number range has not emerged ? Would that not be easier for everyone (Nikon included) ? I'm still waiting for my D800 from adorama.

It is possible that this potentially affects all cameras, since it appears to be a calibration problem rather than a manufacturing defect. If every camera (up until Nikon realized that they needed to change something) was calibrated the same way and the procedure was generally acceptable but insufficient for some build tolerances, it is possible for tolerances to be such that most are good but many are not. So good vs. bad will not be related to S/N, date of manufacture or sales geography. It could just be luck.

Despite my vote 'no' above, it looks like I have a less extreme left point back focus problem than most, so I'm really a 'yes'. Because it doesn't affect shots where I need quick AF (wide, distant, short DoF and side-focus) I'm going to wait until later in summer to send my camera for calibration, so I'm not without it for a couple of upcoming events that I want to shoot. But I'll do more 'tests' this week.

After some testing - I'm not sure. What I see is certianly not as obvious as some examples I've seen.

The images were shot with AF-S VR Micro-Nikkor 105mm f/2.8G IF-ED wide open at a distance of 1.5M (4'10.5") on D800 serial number 30100xx mounted on a tripod, mirror up with cable release.

The target was taped to a window.

The first image show the target with the L, Center & R focal points indicated.
The second image is a 100% crop of the Left focal point target when the camera focused on the left point.
The third image is a 100% crop of the Left focal point target when the camera focused on the center point.

There is some difference, not only in the text but also in the "Sharpie" outline of the target and the blue masking tape.

The right focus point seems as good as the Center.

I guess it qualifies as the "Left Focus Problem" ??

Like you, I think all D800/e cameras achieve different focus using different sensors. The reason why some people don't have the issue is that while the left sensor back focuses, the error is masked by the DOF of their particular lens.

This won't be visible if you test using a paper target on a wall. You have to shoot a test target like the LensAlign with a sloped scale so you can see the range of DOF. Even though the 0 may be in focus, it could be at the very front of the DOF range. With other sensors, the 0 may be in the middle or back of the DOF. The flaw is that they are all different. When you combine that with the particular tolerances of individual lens, you may end up with combinations that result in OOF images.

I tested all of my lens with my LensAlign. I calibrated the center sensor with AF tuning to be in the middle of the DOF range and then checked how the left and right sensors performed. All of my lens showed different focus depending on the sensor but only on certain ones (17-35 & 24-70) was the difference enough to fall outside of the DOF.

It is hard to tell from your test. A flat target is not a good test of AF accuracy when it comes to back or front focusing. Flat targets are for testing lens resolution among other things. In addition, there are lens specific distances which must be taken into consideration. Your 105 lens should be tested from a minimum distance of 8.2 feet and a maximum of 16.4 feet, these lens distances are available at the LensAlign website.This particular problem is most noticeable with wider angle lenses below 85mm shot wide open.
The attached picture is similar to what Nikon uses to test AF accuracy. It is described in the service and repair manual for the 24-70 f2.8 lens. The large target at the top is where the AF point is focused, the smaller targets are resolution charts spaced 45mm apart. It is the same basic idea as the LensAlign system, it just doesn't use a ruler to measure the degree of back or front focus. The target with vertical lines is used to test the center AF point and the one with the horizontal focus target is for testing the outer AF points.

I suggest you take a look at Tom's post (#21) for a good list of the criterion to reproduce the issue.
With my 84 1.4 it was noticiable only with the leftmost sensor. With my 50 1.4 it was pretty much inconlusive but with the 24 1.4 it was obvious on all left sensors and progressively worse towards the outside.
I would try your 14-24 or 24-70 @24 at a distance of around 15 feet.

Be careful about the 14-24, it is known to have focus shift (which is only a factor if you are NOT shooting wide-open) but I thought I had a source indicating field curvature too, but to be honest I can't find that source right now. I'll keep checking to see if I can re-find that source.

Therefore perhaps the 14-24 is not the best lens from which to form critical conclusions about your camera. Because of the possibility of field curvature, on any lens, it may be best to evaluate THIS AF-point-calibration problem by solely evaluating focus at the left point itself and not clouding the issue by looking over to the centre or right. When sharply focused on the left AF-point, a lens with inherent field curvature will naturally be softer over on the centre of the image and vice versa.

Perhaps someone who owns a 14-24 can provide guidance about that specific lens.

When looking at this one:
"The second image is a 100% crop of the Left focal point target when the camera focused on the left point." and comparing it to the last image (and assuming the macro has a flat image field which should be a safe bet for a macro lens).

To me this looks like you have a mild-case of the problem (at least with the 105mm). If it were me I'd want to perform the test a good number of times and perhaps with different targets to prove it. (and yes, by all means try Tom's protocol, especially since longer lenses such as 105 do not appear to be the epicentre of the problem).

I am voting no (i.e. no problem) on my D4 after an admitedely all-too brief test using my 24-70 at 24mm and f/2.8. (BTW, the 24-70 does have a rep for field curvature at 24mm)

I will observe that in conducting my "test" which so far was just a quickie, I find myself also questioning whether lens sharpness at centre vs. as far out as the far left and right focus points must also be a part of one's evaluation. I.e. If a lens is naturally sharper in centre than over as far as the left-most point that could account for a small sharpness loss when comparing left to centre. I haven't done the CDAF test yet either, so to be most complete I'll need to fit that in too.

I'll do some further shooting, but for sure I don't have the severe problem I have seen on some peoples examples posted out on the net.

I have yet to see anyone refer to the 16-35 when detecting this problem? Of course it's an f4 lens so maybe that is enough DOF to mask any but a severe problem?

Thanks to all have given some good feedback!
For one, I got mislead on the correct distance and was too close.
I've got access to a Lens Align and will try it on several lenses.
I guess the trick will to be sure to maintain the target in the same plane parallel to the image plane when testing the various focus points.

I'm really at a loss for understanding what's going on with my camera. I've certainly seen times where the left-most point is not nearly as sharp as the center. But today I went outside in good light, shot a bunch of photos using the left-most point and over 90% are sharp. I just don't get it. Sometimes it sucks, other times there's no issue.

I assume that the fact that Nikon are replacing my camera with a new one, means the answer is no. This seems logical since the AF fine tune is also useless in correcting this problem.

Just to note I have tested every lens I own 24,35,50,85 1.4G's and 14-24/24-70/70-200 and the 'problem' occurs on all lenses to certain degrees (50 1.4 is shocking and totally unusable) All the 1.4 G's seem to be far worse than the zooms but IMHO this is related to DOF. My conclusion is that anything wide open on my camera is off or soft to a certain degree with any AF point but far worse with the left points progressively getting worse the further left you go. But clearly I have a bad copy as I have found 'other issues' that Nikon seem to be concerned about after talking and supplying samples to them.

Nikon for life..

I believe there may be a sensitivity issue with the left AF sensor, which causes it to exhibit the issue only under certain lighting/target conditions. I suspect this is because I observed more than usual hunting with that sensor. In AF-S mode, I often hear the focus servo twice, while the D700 is able to do it in one shot. In AF-C mode, the focus often hunts forth and back, even in relatively good light and a contrasty target, while the D700 is "quiet" (even while keeping the AF-ON depressed). Depending on those circumstances, and also the timing of when the shutter is released (how much delay after engaging AF), I sometimes got good focus with the left sensor. So it may be more than just the AF alignment. This may also explain that in some cases, Nikon service has not be able to fix the issue via AF calibration.

Can someone help me understand these AF issues. I certainly don't have the "best" Nikon glass, but all but one of my lenses is on the "Nikon List" for the D800 as being acceptable.

Tom outlined the conditions in which the "AF issue" might occur - interesting points.

I tested for fine tuning my 16-35 f/4, 24-120 f/4 and 105mm f/2.8 Micro using my Lensalign. They appeared to be spot on. But then the procedure I used was using the center focus point; AF-S; Liveview; at about 30 x the focal length; wide open; longest focal length of each lens; Mup; Tripod; cable release. So some of these criteria don't meet those in Tom's "list".

But I am further confused, as wouldn't the focusing "issues" that many/some are talking about be affected by whether the camera was using its CDAF or PDAF - ie: viewfinder or Screen?

Also, secondly, aren't the focus "sensors" in the array different depending on where they are located in the focusing array? For example the outer AF sensors are one dimensional sensors configured in vertical lines, I think, while the center ones are cross sensors. Would not that make the "type" of target used to evaluate focusing perfromance relevent?

Most of the problems reported seem to be with the outer vertically arranged "one-dimesional" sensors while the cross ones seem OK.

I may be confused here, so please can someone put me right!

What is the best methodolgy and target type to truly accuately evaluate if the camera has this "focus problem"?

Thanks for your enlightenment.

Yes, the issue that everyone is concerned with is only related to the viewfinder PDAF. Everything I have seen says LiveView still works fine.

Yes, if one compares the center AF point to the outer points this would complicate the test. Therefore, given the issue seems confined to the left side, I would advocate comparing the rightmost sensor to the leftmost sensor

>What is the best methodolgy and target type to truly accuately
>evaluate if the camera has this "focus problem"?
I don't know about best, but I might advocate the following.
Satisfy the conditions listed previously by Tom. The goal of the test design is to then elimate the issues that you have brought up as well as others. The preference is for a differential diagnosis to eliminate issues of technique and quality of focus target.
Place the camera on a tripod or other stable device in good light and use high shutter speed. Take photos using the rightmost and leftmost AF sensor by rotating the camera to place the AF sensor on the chosen target which is at the same height as the camera. Since the camera was rotated, geometry is still an issue. Therefore, repeat the test with the camera upside down. Do this for several trials. If the right AF point is consistently much better than the left, this would suggest to me that the issue is with the camera rather than the shooter.

Refinements and criticisms welcome.

Thanks, Brian.

Well, without turning the camera upside down (!), and by purely evaluating the performance of the various focus points I conclude that I do indeed have the L/H focus issue - this on camera serial # 30095xx.

I used the 16-35 f/4 G for the test. I used the Lensalign target but not specifically to determine DOF issues, more to subjectively evaluate focus from the different sensors when viewed at 100%.

I could determine no appreciable issues using the Liveview CDAF system.

When using the Viewfinder (PDAF) I found the Center sensor and all sensors (that I tested) right of center to be acceptable. However the LH (outer) middle sensor was distinctively unacceptable, as was the lower LH (outer) sensor. For some reason the upper LH (outer) sensor was marginally better than the other LH ones. Moving progressively right 5 clicks from the LH outer sensor I found things improving from the 1st click in, and acceptable from the 2nd click in.

It was blowing a gale outside so I did the test inside in rather marginal lighting conditions, but I thinks the results are what they are anyway. (should be evenly good or bad!)

Test settings:

Lens: Nikkor 16-35mm f/4.0G ED N VRII
Tripod; VR Off; M-Up; Cable release; RAW
6 shots each @ Center, Left and Rigth Sensor - Liveview
6 shots each @ Center, Left and Right Sensor - Viewfinder PDAF
3 shots each @ each of the Outer Sensors, Middle/Top/Bottom - repeated for 4 "clicks" in towards center
Settings:
1/15s, f/4 at FL 16mm
Distance to Target 2' 3"

Is this a valid testing methodology do you think? If so I suppose I have to contact Nikon - any thoughts on that?

EDIT: I also forgot to mention that if I focus in LiveView with the focus sensor "centered" on the target, when I switch to the Viewfinder the focus sensor is about 1 "box" lower than in LiveView and slightly to the right. Is this to be expected?

Thanks,

Chris

I did not think I had the AF issue until I followed your advice. I definitely have a left side AF problem when using my 24-70 at f2.8 and a distance of 20 ft. The focus is not off so much that I would notice...for probably months. I tend to swing my camera so the focus point is centered on my subject, focus , then turn my camera for composition and shoot.

FWIW, Nikon just emailed me that they're still reviewing my images that I've uploaded to determine a solution to my problem. Seems like they're trying to sort out the details internally still.

I would say yor method is good. If your going to send images to Nikon, you might want to repeat the test at a higher shutter speed in order to "leave no stone unturned". You know your technique is good and as you say they should be evenly good or bad but Nikon will probably only look at a couple shots and that 1/15s could be used as reasoning if someone was looking for one. Personally, I am waiting before sending in my D800 until there appears to be a consensus solution.

As for your edit, I'm not sure of the proper relation between focus points of the viewfinder and LiveView. Looking at the thread "D800E Focus Points", there seems to be multiple things going on with focus points.

Yes, I'm going to re-do them today in better light conditions. The good thing though is that in every other respect this camera is amazing ... and how often, I wonder, is it that I will want to shoot in a manner where this "problem" manifests itself - ie: very wide, wide open and using the outer left hand focus point, with a desire to critically pixel peep at 100%!

Personally, I think I'll wait for Nikon to officially come up with a "solution" before letting my D800 go anywhere! It's an amazing machine.

For what it's worth, I had my D800E for a couple of weeks before Rick Paul sent me a note suggesting I check out my camera for focus issues or the lack thereof.
I spent a glorious week in Toronto enjoying the Camera at my Urban Photo Workshop for the Nikonians Academy. I did notice that a couple of shots were uncharacteristically out of focus, but chalked it up to user error.

While sitting in the airport lounge on my way back to Vancouver on a Monday Morning, I set my nifty fifty to 1.4 and simply checked the focus accuracy using the viewfinder and sure enough, I noticed a severe lack of focus on the left most focus area. I uttered a four letter expletive aloud. The issue did not occur in live view.

I was debating about what to do. I took my baby back to Kerrisdale Cameras in West Vancouver, BC to my "pusher" Derek. He called Nikon immediately and they suggested sending it to Nikon Canada in Toronto from which I had just come. I hugged it goodbye and 10 days later it returned seemingly in working order.

I now have a smile on my face and I will sleep better knowing my D800E is home safe and sound. The work order listed the following:
"Adjust Focus System" and Replace Bayonet Mount" and "General Check and Clean"
Before you ask, I have no idea how to interpret this work order.
All I know is that I am appreciative of Kerrisdale Cameras and Nikon Canada.

Rick

Thanks for your post. I'm glad your focus issue was resolved.

I'm waiting until after my son's graduation in a few weeks to start the ball rolling with mine. It was purchased at Best Buy so I don't think I will get "VIP" treatment as you did with your camera shop which means I will need to deal with Nikon directly. I've thought about retuning it for a refund but I'm afraid it will be a very long time before I get my hands on another one.

Congrats, I am happy to see your problem resolved so easily. It has been 10 days since I first talked to Nikon USA Tech Support. They sent me one email with instructions on how to submit photos for evaluation and I haven't a word since. Just to recap, I sent them two sets of photos taken with the 14-24 and 24-70. Each set with left point shots and center point shots for comparison. I also talked to the local Nikon service center in Sacramento. They were aware of the problem but did not yet have a fix.

I will take up the battle again Monday.

Great that you got it fixed - congrats!

Interesting mention of the "Bayomet Mount". I wonder if that indicates that somehow the mounts were mounted slightly "off plane" and that contributes to the focus issue?

I sent my shots to Nikon for evaluation and am waitring to hear back.

Enjoy!

Did my checks using lens align target with the 14-24; 24-70 @2.8 and the left side is soft. Right side slightly on the 14-24 Sigh...

I will redo the test in brighter light and try to replicate. Regardless I will hold onto it for a month or two and get a good feel for what it is producing before sending it back. That way I can evaluate the fix when it is done.

Nikon replied to me asking me to do the shots again with a different lens to "eliminate a lens issue".

I repeated the same test with my 24-120mm f/4 - same results. I also did the test in better lighting (f/4 1/160s) but, as I say, the same result - though, to my eye, a tad less bad, but still not acceptable. For fun I tried my 105mm f/2.8 Micro - no problems with that at all, so it does seem to be a problem related to focal length and aperture (wide and wide).

Well I just got this reply from Nikon concerning the second set of images I sent in:-

"This email is regarding your last email. Yes we did evaluate your images and we are recommending you to send your D 800 in for service so we can go ahead and take care of this problem that you are having. Also our hours in El Segundo, CA facility are from 7AM - 3PM (Pacific)".

So, this seems to indicate that they acknowledge the issue and have a fix. As I am going to be coming back from an assignment in Santa Barbara, CA next week I'm going to drop the camera into Nikon's Service facility at El Segundo and go from there.

I have a D800E 30003xx.
Did test today, AF fine tune 200-400mm +10
Shot at about 20 feet at 400mm. Left focus point back focuses about 1 inch. Right and middle are same and accurate.

Tested all 51 points. Used tripod, cable release, mirror up, and flash.

I'm bummed. Leaving for Teton workshop Wed. will have to wait until I return to fix.

While AF fine tuning my lens on both the D800E and my D300 I noticed a huge difference in WB even though they were both set to 5500K. Very odd. How do you manage a shoot?

I have not noticed anything during normal shooting, but not sure how often, if any, I actually did focus from the left, so I decided to
finally test it to be sure - shot same subject, using all focus points from right to left.
The left looked just a sharp as the right...so I'm OK.

I am not sure if I am in the majority but generaly I don't move my focus indicator around but just use the center one and refocus if I have to.
I would be interested to hear if this is a common approach

Just tested in good light on decorative rock on my house. Nikon 16-35 f/4VR at 28mm, wide open. Wireless shutter release, tripod, and VR off. Shutter speeds 2500-3200. I shot 3 shots each all the way to left, center, and all the way to the right. I took the best of three. Amazingly, the best left was better than the best right, but center was noticeably the best, as one might expect. So, I see no focus problem. D800, SN 3012789.

With older cameras like the D50 I really only used the central AF point. But from the D200 on the outer AF points were quite usable and so I started to use them more. Specially if you do a portrait and have the focus on the eyes which aren't in the center of the frame than using the outer AF points is more accurate than using the center AF point and recompose. Now with an FX camera you might not even have an AF point as close to the border as you whish. It's still advisable to use an oute AF point and only recompose very little. The focus error can be minimised this way.

That is interesting.I would like to explore this further.
I had always assumed the central point was the sharpest and you will get the sharpest image by using it and recomposing.
Is this still true or is it much wiser to use the focus points closest to the spot you are interested in and only recompose a small amount?
I can see that for portraits but would it be true to nature photography also?

It depends on your subject and also other camera settings.
For instance 51pt matrix or single point spot focus.

In my MotoCross case, I had less than a second to recompose the next shot and I most wanted to get the Rider and bike in focus.
The dust kicked up by the rear tire only needed to be in the picture.
So, I put the focus point on the Rider.

I had returned my previous bodies that showed that left AF issue. Last week I got a new one which finally has no issue.

Hopefully that's true. My new camera has similar serial number and no issue. However even the previous bodies that did show the issue were fine when used with f/4 lenses, so your test would not prove it one way or the other.

I tried some shots at f/1.4 with my 50mm f/1.4G lens. Inside when taking photos with a tripod of some books on a shelf, it appeared to have a left focus problem, but when I went outside and took shots of a brick wall and a house across the street, I could see no problem whatsoever.

I guess I am not going to worry about it. I am probably the only person here who still uses the technique of locking on the center focus point almost all the time, half pressing the shutter button to focus, recomposing, and then shooting.

The serial number of my D800 is 302xxxx.

Have you tried the 3D tracking ? it works also when the camera moves to recompose and you're sure that what you were aiming at stays in precise focus while recomposing...

The good news is, my D800 has been repaired, shipped via UPS 2-day with today (Monday) as the delivery date.

The bad news is ... UPS seems to have lost it. It left their West Sacramento sorting facility at 5:56 but at 7:49 they updated the tracking to show "an exception has occurred", they are "taking corrective measures".

I have been on live chat support with UPS for over an hour and all I get is weak apologies for any inconvienance this may have caused and a suggestion that I keep tracking the package. He admitted that they do not know where it is but that they are looking for it.

It was very comforting to have him say that he understands my concern. Whew, I feel a whole lot better now.

This brings to mind the question, does anyone know what the UPS policy/procedure is for replacing something of this value?

Years ago I had three Volvo heads in a row "disappear" from UPS Sacramento.
Evidently they were marked on the outside of the box with the contents.
I found this "error" later when the second one showed up.
It was damaged and I think the thieves rejected it.

There was no cost to me, just lots of aggravation as the studs on the one I did receive were broke off and the head had to be done over locally.
UPS picked up all the loss.

Chuck - not happy news, but hopefully it will turn up OK. In this case the shipper was Nikon in El Segundo so there should be no problem in having it replaced by UPS (or even Nikon), as most hassles with couriers such as UPS arise over value/age/condition/packaging etc. In your case Nikon can certify to exactly what it was, and you can directly hold them liable too.

It seems they'll search for it for 10 business days (2 weeks) - then if they still can't find it they start the claims process. Altogether you could be looking at 4 weeks before they pay you for the item (assuming they don't find it).

Details here: http://www.ups.com/content/us/en/resources/service/claims/hlp/lost_process.html

UPS lost a D300 of mine - it turned up eventually.

I mistakenly took the outdoor shots in P mode with the aperture on 8. When I redid the test at f/1.4, it definitely appears to have the left autofocus problem. Yesterday, I went by the local dealer where I purchased the D800 last week, and none of the employees had heard about the problem. The guy I apparently need to talk to was not there, so I am going back soon. I also ordered a LensAlign MkII so I can do some more accurate testing.

Even if I never use the far left autofocus point, I think I need to get it fixed for when I eventually want to sell the camera.

Sad to report that my D800 has the severe left AF issue and a slight softness on the right too. Center is tack sharp. From the beginning I kept stating that I was having a tough time getting a sharp image w/D800 but read that it was due to all of those megapixels or technique. Yesterday I finally took the time to test it and was shocked to see how out of focus the left side was- a blurry mess! I shipped it off to Nikon yesterday via my local camera store & now need to test my D4 but will wait until I get the D800 back. My serial # starts w/ 300 & ends in 102.

I just hope that Nikon is aware of the issue & returns it repaired!

I posted a yes vote for my soon to be returned to vendor D800E. I ran several focus tests, which were a bit inconsistent, i.e. not all of them reflected a left focus point problem. However, the majority did. My feeling is that none of them should be problematic unless caused by user error. I did enough testing to satisfy myself that the problem was not user error. The serial number of the camera is 3001xxx.

I have decided to return the camera to the vendor for credit. That means that I will be out of pocket about $110.00 for two way shipping for a product that is defective. However, I have chosen to do that rather than fight the Nikon repair lottery. There are too many reports of Nikon repair facilities not getting it right. Then one has the responsibility of testing whether Nikon has once again failed to get it right. I choose to wait until Nikon is producing consistently good cameras that can, more likely than not, be counted on to focus and otherwise perform properly.

This, of course, is very disappointing. I hope that Nikon will get its production facilities in proper order and fix this very bad quality control problem. Until I am satisfied that that has occurred I will remain on the sidelines. I am not willing to bear the burden of checking and rechecking to see whether Nikon has, this time, gotten it right. I do not think that that is a reasonable burden to place on the consumer. Others, of course, will disagree.

I only agree because I have gotten so many excellent products from Nikon including my D800.
Unfortunately, it appears that they have succomed to the maladies of nearly every manufacture in the world.
I cannot think of any that have produced flawless products in the last year.

ITA & only wished that I had the option of receiving a credit or a return but the store I purchased it from has a 30day return policy & my purchase is past 30 days. I too feel it is a heavy burden to place on the consumer-for the prices I think we should have confidence in Nikon to release a product that is functioning & not damaged. ;-(

I just got my D800E this week (serial # 3002xxx) and I don't seem to have a left focus issue after testing but did need to fine tune AF for my 20, 50 and 80-200 (-10 to -20 range). However my 24-70 was perfectly fine, go figure.

Serial #3014XXX received on 6/12 shows left AF issue, serial #3022XXX received on 7/2 does not show left AF issue. However, customers receiving cameras as early as a week ago are still indicating issues. Signs are pointing more and more to the fact that Nikon only calibrates the center AF point at the factory, and that other AF points may be off to a greater or lesser extent depending on other factors. However, when you send your camera for service they take more time to calibrate more of your AF points individually. If that's true, I don't know if this will ever be addressed at the factory.

I'm not sure that is a valid conclusion - I suspect this issue is now being overblown somewhat, although it did certainly exist for some (including me)!

I sent in my D800 a month ago for the Left AF issue, it came back with the issue still present. I sent it back yesterday. I checked the service status and under the "Cat." tab is says B2. When I click the "?" it says B2 means "Moderate repair: Major parts needed" I blieve it said the same the first time I sent it in but they said they didnt replace any parts. Does anyone know exactly what this means?

Interestingly, the "Yes, I have the AF issue" to "No, I don't have an issue" ratio has changed from about 1:3 to 1:2 over the last few weeks. Perhaps people are starting to notice it more now.

My D800 is #3010xxx and I have not tested it yet. I have read the many posts on this subject and I have a question on the test procedure. When testing and you use the center sensor you take a picture and then you use the far left sensor and take another picture. When you do this do you move the camera so the left sensor can be put on the same location as the picture taken with the center sensor or do you not move the camera and leave the center sensor on the original location and choose the left sensor (which will be at a different location) to focus the shot? I hope my quesion is clear.

When I did my test I locked the camera down tightly and kept it that way so there would be no question about whether things were moved around. I then moved the moved the focus point around noting carefully where it was pointed in each shot.
It probably would be a good idea to do this setting up specific little objects that you could focus on as you moved the focus point around.

My 800 was returned 4 days ago. I tested it again with the 14-24 and 24-70. After comparing the latest shots with the shots from the first test I cannot tell one bit of difference.

Maybe my procedure was incorrect. The camera was on a sturdy Giottos carbon fiber tripod with a good Manfrotto head. I was about 8 feet from the target. I used the internal meter to determine lens and shutter settings. It was late morning (sun almost directly overhead) on a very sunny day and I was using 14mm and 24mm (widest for both lenses), f/2.8, iso 200 to get the shutter speed up, AF-S, single point, 8mm, don't have the exact shutter speed handy but it was more than fast enough for a tripod shot. I switched to manual, applied the settings and made sure the subject was out of focus. I next moved to the left focus point and used a 3 second delay to snap the shot. Without moving the camera or changing settings I then moved to the center focus point, defocused the image and snapped a second shot. The shot with the left focus point is out of focus (slightly blurry) across the entire frame. Is it me or did El Segundo not get it right?

Btw, my lenses all work fantastic on the D3s and my old D300's.

I look at things much more simply... if the object behind my chosen AF point is not sharp, then something is wrong. You should not look for uniform focus across the frame, as that is dependent upon your sensor plane being perfectly parallel to your test subject. I would expect some variation in this regard however.

I took pictures of the same test pattern using left AF, center and right AF using two different D800 bodies. The earlier D800 body (serial 3014XXX) consistently returned OOF results at the extreme right and left AF points while center is tack sharp. Newer D800 body (serial 3022XXX) the left and right AF points focus almost as well as center, but not perfect, using the same test, shot within minutes of each other and under the same conditions.

If the subject behind the focus point is consistently OOF focus after shooting several shots, then I don't think the problem was fixed. This is also why my personal recommendation is to exchange your camera for a new one instead of going through service, as clearly it's a hit-and-miss situation. If Nikon incorporated a change at the factory in later bodies, we should start seeing far fewer issues with newer batches.

Chuck - this is quite similar to what happened with my "repair" at El Segundo - in fact my camera came back worse if anything. I returned the camera to the vendor and my replacement is as good as I could ever expect. I have recently done some extensive testing with FoCal software and note that the LH and RH focus points are not quite as good as the center grouping (as is to be expected), but more than acceptable for my shooting. I am getting stellar results with my new D800. It's an amazing piece of equipment and I'm now very happy!

I voted no. I did not see any out of focus condition using the left sensors. I used a AF 24mm f2.8D lens at f2.8 at about 5 feet with the camera mounted on a Gitzo 1325 MK2 with a Acra Swiss Ball head and used a remote sutter release. I did not move the camera and took 6 shots (1 center and each of the 5 left sensors). Again my SN 3010xxx.

Interesting as I had a expensive item that I had insured disappear in the Sacramento area too- hope they find it & that Nikon insured it properly!

For sure there is a selection bias in these types of polls. Hopefully the D800 on this site who have a 'good' camera are voting too though. Of course, owners subjectively deciding if their camera has a problem or not is another huge confounder here.

Just tested the one I received on Friday afternoon. Unfortunately it also suffers from the AF issue. It is worst at the far left point but is also obvious in other points towards the left hand periphery. I used a 50mm f1.4 to test and compared the AF with Live View. It was really obvious that the affected AF points were much below the performance of the "good" ones.

I'm not messing about and will send it back tomorrow. Its a shame because otherwise I really like this camera. I will ask for one replacement and if that's fine, then all will be well, but if not I will wait until Nikon sort it out.

EDIT Meant to say the serial number is 603****

It's not very reassuring that even recent deliveries still have the issue. The only solution may be having a service center recalibrate the camera. I'll find out how my Melville service went tomorrow evening after UPS drops her off.

My D800 had left AF focus since I got it in March 2012. Since then, I mainly used center AF focus mainly for taking photos. Recently sent my D800 with 24/1.4G for service last Thursday and got it back on Friday. In the report, it wrote: computer calibration on D800. This weekend, I took photos with D800/24G handheld, it focus accurately and not hunting. Plan to test it with tripod when i have time.

I sent it to Nikon Malaysia after reading Ming Thien's blog where his D800E's focusing issue was solved.

Alex,
I also ran into this issue. My camera S/N is 30234XX. I just sent my D800 to the same location on Friday. Perhaps we could keep in touch relative to our communication with Nikon and how the repairs turn out?

I write for Mansurovs and posted this yesterday morning:

My D800E, SN 3002781 seemd to be working quite well. I recieved it July 3rd. It has some of the old firmware (L 1.004), so I do not believe it is one of the most recently assembled.

I tested the autofocus per the Mansurovs procedure and also by comparing the autofocus to live view focus. I saw no difference at f/2.8 on my 24-70mm or 70-200mm.

As an aside, if you want to see some great moire', print the Mansurovs test pattern on a laser printer and photograph it at f/8. I suppose it depends on the focal length setting and the distance to the target, but what I got was really impressive. The little dots in the half tones made some interesting and quite colorful patterns. Unfortunately, I moved everything and didn't get back to try f/16 -- the diffraction at that stop is supposed to reduce the moire' effect.

I believe that is actually an extra 3,000,000 which is beyond their production capacity according to Thom Hogan.

Just received the camera back from Melville today. It arrived there on June 20 and it was delivered back to me today (July 9) for a 19 day turn around from the time they received it. The repair sheet called the service a B1. The following descriptors were used:
ADJ DEFOCUS CONTROL
ADJ AUTO FOCUS OPERATION
CKD COMMUNICATION
FIRMWARE UPGRADE
CLN CCD
GENERAL CHECK & CLEAN

I've just shot about 100 more photos comparing the left and center AF points, and I have to call the issue 'fixed'. The left AF focus is much more consistent, doesn't hunt back and forth as much as it did before sending it in, and the consistency of 'in focus' shots is greatly improved.

Time to shoot happily and forget this issue ever existed. I'd recommend anyone with the problem send it to Melville. They seem to have a handle on the problem.

Hooray- a successful repair!!!

I received a call from the camera shop that was to be sending mine in & they asked me 1. If I purchased it from them & 2. When & 3. Why was it not sent in as a warranty vs: repair.

Not feeling too confident after that call- lol!

Interesting. My repair sheet said the exact same thing a month ago, and still had the issue, so sent it back. Currently when I check the online status, it says its now service B2 (major parts needed). Dont see what changed from the last time they had it in service!

Got my D800E back from El Segundo today.
Quick test seems fine. Left Right Center points look good.
I'm not going through a thorough testing. I will see how it operates in the field.
Invoice says;
Adj Auto Focus Operation
Ckd everything else
sharpness
image test
focusing mechanism
focus tracking
infinity focus
general check and clean.

Good luck to all.

Perhaps a month ago they didn't have the "fix" that is supposedly available now. Nikon El Segundo received my camera yesterday and shows it as the same B2 repair. I'm keeping my fingers crossed.

D800 and a bunch of glass that cost way more than my wife thinks it did.

Just got my new D800 (moving back to nikon after a few years of Sony full frame, happily). Since the intarwebs are filled with complaints, I thought I'd throw in a positive datapoint.

First calibrated my 50mm 1.8 with the new FoCal software (a great experience!).

Then did a slapdash center/left/right test with the 50mm based on this blog post:

http://mansurovs.com/d800-caviar-sardines-orspam#more-32923

My results... first, the setup:

http://www.highway30.org/forums/focus/target_setup_50mm_f2.png

Then, the center target, with center focus point for reference:

http://www.highway30.org/forums/focus/center_target_cFP.png

Next, the left target, once using the left-most focus point, once using the center point (on the center target) for reference. So if I use the center focus point, the target out to the left is fairly in focus. If I use the left focus point *on* that target, it is in about the same focus. Right targets look similar, so I'm not showing them here. Seems tolerable to me.

http://www.highway30.org/forums/focus/left_target_cFP_lFP.png

Last, for comparison, the left target, once with live view focusing on the left target, and once with the viewfinder/phase detect focusing on the left. Again, fairly consistent.

http://www.highway30.org/forums/focus/left_target_lFP_pd_lv.png

I know ideally folks are testing with wider lenses. 50 is as wide as I go at the moment. If I get a wider lens in the near future (zeiss 25? voightlander 20? nikon 16-35 f/4?) I'll test again. I don't expect an issue, but I'll tackle it then if it's necessary.

Now, out to shoot!

The Voigt and Zeiss won't help you test this one... they are manual focus lenses.

Is there a simple, repeatable test with a given focal length, aperture and distance that makes the focus issues obvious? Simple meaning no extra software or test targets required.

Is a universal test procedure even possible because the exact focus errors vary from camera to camera?

Thanks. Not sure if that qualifies as "simple" as the description is over 2,600 words in length, but it looks to be a well considered procedure.

However, the following words do not inspire confidence:

"Still, it will be hard to pinpoint the exact source of the problem, because it all depends on how badly calibrated your lenses were before you started the test."

This issue won't stop me buying a D800E - I am giving Nikon until Photokina to come up with a D400 to compare - but it would be reassuring to walk into a shop and be told "We did the Nikonian test with focal length x at aperture x at distance x and this camera is fine".

I want to take pictures, not stick targets on my garage wall.
