None of the Lenses required any AF-Fine Tune adjustment, meaning AF-Fine Tune is OFF. All of the Lenses were reasonable sharp at Center, Right and Left AF Points, the only exception was the 28-300 at some high focal lengths ( > 100mm) that was just a little bit Out of focus.
Just as a reference, I've done the same tests, multiple times before with 3 D800 (S/N: 302XXXX, 304XXXX, 305XXXX), and I had Left AF issues with ALL the lenses all the time.
Clearly this D800E is a winner, and there is hope that Nikon might have finally resolved the Left AF problems.

I returned the second bad d800 and upgraded to a D800E serial # 30060xx, so far focal testing less than 5% variation between sensors, no left or right focus problems and when checking af fine tune with my lenses, both on focal for the shorter ones and lens align for the longer ones, no af fine tune correction was needed. Looking forward to using this camera. A couple of real world shots with the lenses confirm the autofocus appears fine.
Edit: I had to do a -20 on my lens and it still is slightly backfocusing (to me). please tell me if i am crazy on that. I think it is close enough that I am unwilling to send the camera back since it appears the focus is pretty darn close.
The 21 mark is where the object is alinged .
I set up my Nikon 70-200 VR1 and set a metal yardstick at a 45 degree angle with a target next to it. I took 2 photos from center/left/right and picked the best to post.
2 things .. i am not a professional, so i am certain there will be some that poo-poo my test, however here is what I got .
AF fine turning requires the camera to be in proper position to the target. Lensalign and focal check alignment before you check and adjust fine tuning otherwise it will not be spot on. You can do it with a target and ruler but may not be accurate. Focal also checks sensors and is semiautomatic, lens align is a bit more intensive as far as what you have to do to check things out.
Since the first 3 lenses I tried adjust on all needed -20 to get close I am going to get string and my level to make certain I have everything lined up.
I am REALLY hoping I find an error on my part. I cant see myself keeping this camera if all my lenses need -20 to get close.
I will HAPPILY eat crow if I find that I made a mistake and will definately let everyone know how I goofed. I can laugh at myself. ;- )
I downloaded another target and placed it on the floor. I ran a string from next to that to a lightstand and used my 45 degree angle to get a guide. I placed my camera on a sturdy tripod next to the string to eyeball that it was 45 degrees. I used mirror lockup. I then locked down the tripod so the camera body would not move and change the focus location.
First I took a shot using live view to have a reference. As expected it was sharp where I aimed.
Without moving the camera I turned off live view ... manually turned the focus to the far end and made it refocus. The middle dot light up saying that is the point it used, so my assumption is both locked onto the same place on the target.
Even at -20 on 3 lenses I am still slightly backfocusing. The target looks sharp where it was aimed, but I can see the numbers behind are clearer further than in front
I have the Nikon 70-200 VR1 - Nikon 28mm AF-D and Sigma 50mm macro that I tested with.
I shot the target from roughly minimum focus distance on all, except the macro lens, it was about 18-24" from the target.
I am torn as it seems the left-center-right focus points are all perfect, except for the slight shift backwards, NO issue with it being soft on one side.
I'd hate to send it back, wait weeks/months to get one and hope for no focus issue.
I wonder since it is the same across all the lenses I own if Nikon can/will make a tweak to bring it back in line ?
Even if I had to do -10 or - 15 I would not be bothered, just -20 and it is still not perfect bugs me as there is NO ROOM for more correction as things loosen up over time.
I just do not know what I will do. It is close enough that in real-world shooting I am unlikley to notice any problem, until my lenses and/or body work in and loosen up.
Try using the FoCal AF fine tuning software from Reikan Technology. It will tell you if the target is aligned/position properly and if it is properly illuminated for good calibration results.
The graphs you get at the end when you save the calibration results will show you a nice curve and how the test data points fall along that curve. Even if the AF fine tuning comes out -20, you will see why from the data on the graph. You will understand that the adjustment is not arbitrary.
One of the things I like about FoCal is that it works through a tethered connection between your computer and the camera. You do not have to transfer test shots from the camera to the computer and keep track of them. Of course, it requires a computer next to your test/calibration setup. I did mine in a garage where I could control lighting and there was no wind to screw up my test results.
I recommend the Pro version for maximum calibration and testing controls and results.
I called the Nikon Store today to ask for a solution. They are going to "research" one for me and get back with me. I am a little disappointed they would not give me an RMA TODAY, so that I could look for another one however I guess I am at their mercy.
-20 is unacceptable to me, no room to make further adjustments. /sighs
What a nightmare. I decided I wanted to just return this camera to the Nikon Store. This is the second employee that had NO CLUE about an RMA number or even how to get one. He agreed -20 was way too much, but had no clue how to get me an RMA.
This rep told me he saw nothing in my account from my last phone call. One of the two reps lied to me. First one said he would be looking into it, so an entry in the system would have been entered (one would think). The second one said no entries found.
WHAT THE HECK !? ... do they even train their employees ?
He came back after a while and wanted to know where I bought my lenses. WHAT does that have to do with anything ??? Then back on hold. /facepalm
He wanted me to try and return my 3 lenses because he thought THAT was the problem. AHHHHH !!!!
Finally I got it through that ALL I wanted was a refund. They do not show as available at the Nikon Store, so no swap was possible. He put me back on hold.
He came back and said he had no clue how to issue an RMA. He is researching it as I sit on hold. He began to read me what was on the Nikon Store page inre RMA. I know that as I already looked it up before I ordered and had the page up as I dialed them to ask for one.
Now I have to be transferred to a supervisor to get the RMA. (after 30 minutes with this first rep)
I have to wait for the supervisor to call me back.
I am taking bets on them NOT giving me a refund. /sighs
Are you sure you have a problem? Normal depth of field would show 1/3 in front of your point of focus, and 2/3 behind it. You should have more in focus behind your intended target than in front if everything is working like it should. Or maybe I just misunderstood your description.
>I have to set it to -20 to get what you described. I tried >for 3 days to show myself up and find a mistake. I REALLY >wanted to laugh at myself. > >I love what this camera does (i am coming from a D90).
Yes, you made a mistake but it is very, very small. Your target should be parallel to the camera not at the angle. But your scale/ruler should be at 45 degrees. This kind of mistake will give you maybe 2 points variance at the most which in real life can only be affecting lenses like F1.4 at wide open on tripod. But at -20 it is very bad. My camera, D800e came with -15 on all lenses. I dropped it off to Nikon in El Segundo and within 1 week they adjusted it to -5. If I have time I will drop it off again so they can do it at Zero but at this point I am OK. BTW, 24-120, 16-35, Sigma 50-500mm OS and Sigma 85mm F1.4 are all at -5. I just got 28-300 and it is at -2.
I was tempted to have them try and do a repair. I just did not have enough confidence in the repair to bother with paying to ship it in. Had mine been -15 they would not have heard from me until a slower shooting season for me.
I still do not have the email with detailed instructions on how to send this back. I will give it until tomorrow, then call again to ask when that email is going out. I got the one where it said an RMA was created, but to wait for an email with instructions.
Of course no D800E's are showing as available now like Friday when I started this RMA thing.
I wonder what difference it makes if the target or camera is 45 degrees, though I did it both ways. first with the target at 45 and someone said that was wrong, so i tried it with the camera at 45. I tested for 3 days trying to prove myself an idiot so that i could keep this camera. Today I wish I were an idiot and descovered my error instead of having to locate another one and hope it is AOK
Today I tested my new Nikkor 28mm f/1.8G lens with the D800E (I got this Monday) and at first with no Micro Focus Adjustment, the Center was sharp, and the Right and Left were a little bit out of focus, then I did the Micro Focus Adjustment process to the center point, with an optimal result of -5, and all three AF points Center, Right and Left and super SHARP.
