"D7000 vs D700 vs D3x"


US
          

I too am having difficulties with the D7000. Attached are three photos, all taken using a Nikon f/2.8 70-200mm with the TC-20E III at 400mm with VR off. The initial images were cropped (using Photoshop) to cover approximately the same area for comparison purposes. No other adjustments were made. These were taken under different lighting conditions. All three cameras were set to matrix metering, focused on infinity, WB auto, sharpness normal. For purposes of this post, all three were uploaded at 800 pixels wide.

The quality of the D7000 shot appears inferior to me. Any comments or suggestions would be appreciated.


Camera: D700 with cropped area of 830 x 503 pixels
f/7.1, 1/3200 @ ISO 800, NEF = 14,816kb


Camera: D3x with cropped area of 1,183 x 719 pixels
f/7.1, 1/2500 @ ISO 800, NEF = 50,008kb


Camera D7000 with cropped area of 1,467 x 885 pixels
f/8.0, 1/5000 @ ISO 1600, NEF = 21,384kb

No "pun" intended but all three look inferior to me. They are all out of focus. So to me its not that the D-7000 is the worst.

Sorry, but I am also under the impression that all three are out of focus. Perhaps you want to try the same with another subject

I have to agree with the observations that all 3 images are inferior.

How far away was the mountain? Used with the same focal length, aperture and subject distance, the two FX cameras will provide greater depth of field than the DX D7000.

The "normal" setting does not necessarily give the same degree of sharpening on different cameras.

Hi Brian;

The mountain is 10 to 11 miles away with the foothills in the full-size image maybe a mile-and-a-half closer. Looking at the D3x and D7000 originals top to bottom in Photoshop at 100%, I don't see an appreciable difference in sharpness. The uploaded FX images show about 20% of the originals width and the DX about 30%.

I took four images with each camera, handheld, two with VR off and two with VR on. The differences in quality within each set were minor compared to the differences in quality that I see between the D3x and D700 images versus the D7000 images.

Should I expect greater sharpness handheld with the D3x and D700 with such distant objects? With the relatively low contrast and smaller lens openings, could this push the autofocus of the D7000 a bit beyond it's capabilities?

Thanks

At that sort of distance, changes in atmospheric conditions (you said that the lighting was different, so I assume these were taken at different times) could have a big impact on clarity and contrast.

I wouldn't draw any conclusions about camera/lens performance from this particular "test" setup.

This is kind of a poor subject for making this kind of comparison. As stated above all three are soft and lack contrast.

“These were taken under different lighting conditions. All three cameras were set to matrix metering, focused on infinity, WB auto, sharpness normal.”

There are many variables that can affect a distant subject especially if the lighting is not consistent. Haze, air pollution and other environmental conditions can make a huge difference in the perceived sharpness of distant objects.

To do a decent comparison you have to eliminate as many variables as possible.

Shoot a closer, well defined subject such as the license tag on a car at 100 feet.

Use a tripod. (VR OFF)

Shoot all of your test images at the same time so that the light is consistant.

Use live view to confirm focus before shooting.

Set exposure manually and use the same settings (shutter speed, Aperture and ISO) for each camera.

Set White Ballence to Sunny or other appropriate setting. (just don’t use Auto WB)

Shoot a series of 3-5 shots per camera and choose the best image from each camera.

I am certainly no expert but all three look over exposed to me. Also I know there is a fundamental difference with FX and DX format cameras but wouldn't be appropriate to shoot the subject with the same lens, ISO, and aperture, varying the shutter speed to meet the same exposure based on the metering system of each camera. The metering system is also a performance parameter if each camera. However, I would think that each metering system is reasonably close to one another. Of course a tripod would keep the field of view and stationary mount the same for each.

FWIW,

Rob

“wouldn't be appropriate to shoot the subject with the same lens, ISO, and aperture, varying the shutter speed to meet the same exposure based on the metering system of each camera.”

No... If you use the same Shutter Speed, Aperture and ISO under identical lighting conditions the exposure in each image from each camera will be identical. Using the cameras meter could cause the images to have inconsistent exposures making a comparison difficult.
Even using a single camera the meter can change considerably between spot, center-weighted and matrix metering. The framing of the image can also cause inconsistent metering especially with matrix metering.

Given the different formats wouldn't using those same parameters on each camera have differing amount of light on the sensor?

No - what Dave says is quite correct. Exposure Values (the combination of aperture, shutter speed and ISO) are entirely independent of camera format. ISO 100, f/8 at 1/125th will give the same exposure on anything from a tiny Coolpix to a 10x8 inch plate camera

Thanks for the suggestions Dave. This actually started out to see if I could handhold a 400mm lens rather than a camera comparison. When I saw the much poorer-than-expected results with the D7000 I checked against the other cameras. I will try your suggestions, including the tripod, but I hope to be able to shoot much of time handheld. The D7000 has so far been a challenge for me.

Regards,
Jim

I would bet that in time you will be able to get sharp handheld shots @ 400mm with the D7000. Shooting handheld at 400mm takes some getting used to and the higher pixel density of the D7000 make it just a bit harder than the other cameras.

Yes.

In re-reading the original post, it occurs to me that we're talking about $10,000 in gear.

None of the images look sharp. Clearly there is an issue.

Hi Folks;

I am satisfied with the results I am getting with the FX format cameras using smaller focal length lenses. I would have expected better than I got with the D7000 and the long lens. I appreciate the comments that addressed this. Certainly my handholding capability could be a major contributory factor. I don't think cost has much to do with it.

Hi,

this work is very interesting and thank you for it!

and yes, you’ve got three of the best gears and none of the picture look sharp..so I’m afraid there is an issue with the test or with the lens..
If you want to show differences between Fx and DX, you have to follow laboratory’s conditions.

now the question is: is a D3x more sharp than a D7000..Even if i own a d7000, i hope so..because there is a real difference in the price!!

My idea is to learn and try to use the d7000 as best as possible and be happy with it.

best regards

There is much more to that comparison that simple "sharpness". I doubt whether most people could distinguish a D3X image from a D7000 image in a "blind viewing".

Especially at sizes around or under 12x18...

BUT in general, I think a "blind test" of a whole range of cameras would be really cool to set up, from a D40 to a D3x. I wonder if the tonal quality is where differences could be picked up.

Yes, I expect so. With the right subject (i.e. not like the subject in this thread), any dynamic range differences might become visible.

thanks for your reply,
You’re surely right. I just wanted to say i could understand a small difference in sharpness due to a really big difference in price…but if sharpness is equal, that’s wonderful for us!

The ISO for the d7000 is 1600 vs 800 for the others.. that will definitely introduce more noise.. it is not a apples to apples comparison...

I'm finding that the D7000 (like the D90) is a little soft out of camera, and needs more sharpening than my previous cameras (D50, D200). Maybe it's just me, but with the pixel density the D7000 offers, there's a new learning curve to get your images looking their best.

My D200 handled an in-camera boost in sharpening and contrast quite well. And, to my eyes, needed both to really shine. Nikon tends to leave these values very conservatively set on some of their models.

My own experience with the D7000 is the sharpening can be set at 6, perhaps 7, but definitely 6, which snaps things right up, without any detectable issues being introduced.

Even in Post-processing, whether needed or not, the D7000 RAW images are able to handle a lot more tweaking than my D200 RAW files could.

As has been discussed elsewhere, with the increased pixel density, when viewing at 100%, a 16mp sensor will reveal issues (slight movement, lack of tack sharpness) that may have gone unnoticed before. But keep in mind that, unless they're glaring, many of these issues may likely be invisible in a 12x18 print.

Thanks for all the informative comments, they are appreciated. These lead me to ask a few more questions.

The NEF images were uploaded by copying with Explorer and they were opened in Photoshop. Am I correct that with this process no in-camera sharpening setting would be applied automatically when the image is opened?

Does a low contrast subject combined with an f/7.1 or f/8 lens opening (a bit below wide open on a f/2.8 with a TC-20) challenge auto-focus on Nikon DSLRs? And might that provide an especial challenge for the D7000 or can I forget about this?

I'm a little surprised at the suggestion to not use Auto WB. The colors that I have been getting match nature pretty closely as to warmth/coolness (as viewed on a color calibrated monitor). What problems does Auto WB introduce?

Thanks,
Jim

Yes. Only View NX2 and Capture NX2 will open the NEFs with all in-camera settings applied.

I think the AUTO WB on the D7000 is phenomenal.

1. Yes … Most camera settings, including sharpening, are ignored when opening in Photoshop. You can apply sharpening in ACR when you open the file.

2. Low contrast can be challenging for any AF system. The D7000 should not have any more problems with low contrast scenes then the other two cameras.

3. The suggestion to not use Auto WB was stated in the context of a side by side comparison of the cameras. Each camera may calculate the WB slightly different and make it harder to compare image quality.

In normal use Auto WB works quite well on these bodies.

I don't see any blue sky in the photos. Was is cloudy or hazey? At 10 miles it is easy to pick up any haze in the air.
The D7000 image definitley looks softer than the other two. Try setting noise reduction to low or off and set in-camera sharpening to 5 or 6.

I doubt that focusing (whether auto- or manual) was a factor in your test - the images' EXIF data confirms that all three were (as you said) focused at infinity.

Why not shoot at base ISO? 1600? come on. Shooting with the TC-20 is not optimal IMO for a test like this. Did you use a sturdy tripod for this test? As everyone else is saying, 10 to 11 miles away shooting at infinity? again, come on.
You need to rethink your test, I'm sorry, but this proves nothing useful.

If you ever get time I would love to see the D3X vs. D7000 at base ISO!
(I like to think of my D7000 as my personal D3X stand-in )

Also, feel free to re-post about what specifically might be bothering you on the D7K. We may have missed over glossed over that issue in this discussion. Certainly it is a dense little sensor that would be 36+ megapixels were it full-frame and that comes with many resulting challenges.

Back to basics - at the shutter speeds used camera shake is unlikely to be the cause of the quite obvious unsharpness.
All camera body instructions have a section on getting good results with AF - including a warning AF targets like the one you used can fool cameras into focusing inaccurately. The advice is also on the web
http://nikoneurope-en.custhelp.com/app/answers/detail/a_id/4585
Digressing the individual sensors in the D7000 are larger than in the 2 FX bodies. This might be the reason the D7000 image is the least sharp.
Why not try again using manual focus instead of AF?
I agree there can be loss of image detail due to the high ISO and the atmosphere effects with a 7 mile distant subject, but the varying sharpness indicates AF failure is the most likely cause of the poor results.

Photography is a bit like archery. A technically better camera, lens or arrow may not hit the target as often as it could if the photographer or archer does not practice enough.

As pointed out above, the EXIF data confirms that all three images were shot at infinity focus distance. I don't see AF performance as an issue in this case.

Hi all,

It would be very interesting to compare with the same aperture, same shutter speed and same iso and finally look at the images to find the differences.

Some yes some no.
The distance is said to be 7-8 miles.
I have yet to get EXIF to show more than about 1 mile.
The focus distance could be short relative to a 100% crop (which reduces the depth of field available by several stops) even though infinity is recorded.
It makes good sense to start with the obvious - the target is about as close as it is possible to get for inaccurate AF - so try manual focus as a comparison

I am waiting for some decent weather (stable conditions) for trying the suggestions given here. In reviewing all the comments several times, I am learning a lot and, of course, have thought of more questions. However, I will leave most of these until later.

I am still curious about the EXIF focus distance information. Below is an image where the EXIF indicates the focus is infinity, yet the distant parts of the image are obviously out of focus. I must be misunderstanding something here.



Handheld, ISO 400, f/5.6 @ 1/1250, D700, 70-200mm f/2.8 @ 200mm. Processed in PhotoShop with only changing image size to 800 pixels and NEF to JPG.

>Below is an image where the EXIF indicates the focus is infinity,
The distance the lens focused at is about 250 feet - so the EXIF is likely showing anything further than 250 feet as infinity.
How do I know the focus distance is about 250 feet?
An "old trick" is a 50mm lens on FX covers a 10 foot wide subject at 5 yards focus distance, a 200mm lens does this at 20 yards and so on.
Based on the size of the horse the picture area is about 40 feet wide, indicating a focus distance of 20 yards (for 200mm) times 4 (for 40 feet wide subject) - or 80 yards - about 250 feet.
Back to the original pictures, as EXIF shows infinity at around 250 feet in this latest picture, the lens could focus at 250 feet and indicate infinity with the mountains 7 miles distant.
As the background is already out of focus at 250 feet it could also easily be as soft as in the first 3 images if the AF was fooled into focusing at the wrong distance by the low contrast and lack of distinct detail in the distant hills.
When you get a clear day using manual focus you could do some test shots around infinity on the focus ring (which should be decently sharp) and also progressively closer to learn how close you have to focus to get the EXIF to record closer than infinity with this lens.

Photography is a bit like archery. A technically better camera, lens or arrow may not hit the target as often as it could if the photographer or archer does not practice enough.

Thanks very much Len; that helps me understand what's going on (and what the EXIF data is saying) a bit more.

As to the focus point, it was at the top-center of the horse's body.

Wednesday is supposed to be partly sunny, and then it's back to PC for awhile. We'll see.

Check out this interactive DOF calculator:
http://www.dofmaster.com/dofjs.html
If you focused on the horse at a distance of 250 feet,at 5.6 with a 200mm lens the near limit of acceptable sharpness is approximately 205 feet and the far limit of acceptable sharpness is approximately 318 feet. The calculator and accompanying charts may help you understand what is going on.

It was sunny this morning but cold, so these are just practice images to test the test conditions, so to speak.   The handiest place for the license plate was about 150 feet away (50 paces).   In the real test I will be shooting indoors with an open deck door.   This will protect the camera and tripod from the wind, which has been and is predicted to be "active" here.   Today I did not open the door as it was just above 0 degrees F, so the shots are through glass.   All shots were with manual focus and there was no PhotoShop processing except for conversion to .jpg and the crops.

I left the D700 at ISO 800 because I have read that noise shows up appreciably more above that.   I used a MC-30 to fire the camera.   I left the D7000 at ISO 1600 because I was getting camera movement while finger-pressing the shutter release, so opted for a faster shutter speed.   The D7000 was shot with both live-view and normal - the best shot happened to be with normal, but that could have been a focusing issue.   For the actual tests my intent is to use the same ISO after getting any comments that come in for the following.

Should 1/2000th overcome the camera movement I see in finger-pressing the D7000's shutter release, or should I stick with 1/3200th for the tests?

Which is more likely to degrade image quality at these shutter speed and ISO pairings, noise or camera movement?

Would I be wise to place the D7000 on the heavy dining room table (with the lens propped up by a heavy book) or with the shutter speeds used is the tripod mounting okay?

Finally, are the practice shots beginning to zero in on the kind of resolution the cameras are capable of with this lens and the TC?

Thanks for any guidance you can give.
Jim

Suggestion, use the mirror up setting and try these shots again at a lower ISO, 200 perhaps as it's bright daylight and the higher the ISO the more detail is lost as I understand it. IF the shots are dramatically underexposed after WB, (EV steps) then move up the scale in ISO.

I have shot a few stellar landscapes with the D3S, and D7K in the same ambient light and both sets of capture are well managed although one lens was 70-200 f2.8, the other 24-70 f2.8.

I do use MUP when all things are still and absolute detail is the goal.

Just my .02 cents.

yes, i don't understand why you work with so high iso. to do this test in daylight, you don't need high shutter speed.

what we can see is that 1600 iso is less sharp than 800 iso.

Jim,

I think this was a pretty good test even with the differing ISO values. In fact it shows how well the D7000 stands up against the D700 at least up to ISO-1600.

While you and others see the D7000 image as being softer then the D700 I do not think that is the case at all. Many things other than resolution can affect our perception of image sharpness.

In discussing an exposure issue Thom Hogan said that the D7000 processes image somewhat differently than other Nikons. The image gamma tends to be a bit higher from the D7000 then it is from the D90 or D700. This causes the images to look slightly brighter with lower contrast. This is one of the reasons people feel that the D7000 has a tendancy to overexpos. The higher gamma increases the mid tone values of the image and as a result the images have a little lower contrast and often look less sharp.

Look at the blue color in your two images above. It is not quit the same. The D7000 is a bit lighter and washed out. The fact that the D700 image is a little darker and has more contrast makes it look sharper then the lower contrast D7000 image when in fact both images are equally sharp.

Here I opened the D7000 image in Photoshop and ajusted the Gamma.
Image > Adjustments > Exposure... Then moved the Gamma slider to the Left to a value of 1.27. I made no other adjustments. I made no ajustments to the D700 imange.



I can see no significant difference in sharpness (or noise, or detail) between the images. Both images are what I would expect to see of a deep crop, strait out of the camera with no sharpening applied.

To further illustrate...
I copied a small square (indicated by the red border) from the original D700 image a pasted onto the D7000 image. Except for a bit of misalignment (Mostly noticeable in the “o” in Wyoming) you would have a very difficult time being able tell this had been done without the red outline.

Hi

I've been following this thread on and off and see you are making comparisons between the D3X, D700 and D7000. I have no experience of the D3X but plenty of the D700 comparisons. Just about everyone on this forum remembers my torturous journey, from a returned faulty D7K to soft images and many issues a bit similar to yourself. I would like to offer some friendly advise to consider. Stop comparing the D7K to any other camera, let alone the D3X/700. Imagine this is your first Nikon dSLR and you are starting from scratch. I say this because of my own experiences and am offering it as I once shared a similar situation.

So, ok where am I now and what did I learn? Mostly, I listened to others and I decided, eventually, to stop making comparisons between the D700, D90, D300 etc.etc and the D7K. I started to listen to advice, but started developing my own techniques. What I did learn was over about 400mm with a speed over 1/500th handheld turn VR OFF. Use a Monopod or tripod with VR OFF on long shots. Increase the speed to as much as I could get, whilst trying to maintain between f7-f9. To achieve this I used the wonderful high ISO's if required. If you take jpegs only use the in-camera sharpening and try the different settings. I sometimes take jpeg and put mine to +7, but as I take RAW mostly and process in Lightroom 3/CS5 often the sharpening isn't an issue. The only legacy I have is that my 80-400mm does not perform well on my D7K, I don't know why, but it works fine on my D700. I now use a 70-200mm f/2.8 + x1.7TC for birding.

I have scoured my photo history. I have have now deleted nearly all the images that I used during my struggle to tame the D7K. However, I have found 2 images.

Anyway, the attached two images. Both with a 70-200mm + x1.7 TC and a focal length of 420mm (35mm format)about the same distance away, approx 150 yds and images cropped to about only 5%.approx. The first is typical of my early attempts, the second last week.

I don't know if any of this helps you or others, but persevere. Incidentally, I too went through all the tests using charts, chimney stacks comparing D700 with D7000. I got so confused my wife even said "enough"! Irrespective of what you use the camera for, landscapes, portraits, wildlife etc. my images have improved 10 fold by treating the D7K as an individual, stand alone camera with no comparisons. My technique with the D7K now bears little resemblance to that used with my D700. As with any camera some basic techniques of course remain the same.

Good luck

Richard

I guess it's time to summarize where things are in my view.  

First, the significant lower quality of the D7000 image:   I believe this may be due to the focusing system of the D7000.   In this instance (low contrast, auto-focus) the D7000 did not get as good results as the other two cameras (granted none were "sharp").   Using manual focus all three cameras produced similar results.   The first two D7000 images show the cropped original (auto-focus) and below it the cropped second try (manual focus).   As has been suggested, atmospherics at 10 miles may be impacting quality in all as well as camera movement.






The following shows the entire image (it has been adjusted in PhotoShop).   A line points to the place shown in the last image which has been cropped and enlarged to show pixels.



The image below is the same as the second one above, but it has been adjusted in PhotoShop.  



The above is still not "sharp".   However, I am wondering if, given this type of subject and at this magnification, just how much improvement to expect with better photographer skills?   Looking at the pixels below, it doesn't seem to me that the individual trees can ever be made to appear really sharp.   Is this correct?



I have chosen to use high ISOs because most of my shooting will be hand-held (and I need fast shutter speed to overcome that) and I need more depth of field for some subjects, such as the one below.   It has been sharpened.   This is was taken at ISO 1600, 1/1000th and f/16 with the lens at 400mm.   I would appreciate your comments on sharpness here too.

Many thanks to all who have responded.

Jim

f/16 is well into the range where diffraction will lessen the lens' resolution capability.

thanks a lot Jim for all this work.

just an idea: did you try to do the fine focus tune? Perhaps it’s really necessary with the D7000..
i had to do it with my 18-105 lens to have very sharp pictures..

As it appears that a lot of knowledgeable people are following this post, I would like to ask another question.


Your crop's with the D7000 have considerably more pixels than either FX cameras. Although pixels are more compressed on a DX sensor I would have expected sharper images with the D7000.

I am under the impression that one of the major "benefits" of a DX body is the "Crop factor" for reach.
This obviously helps on the long end where you get an extra 50% reach with that expensive glass.

If your results are reproducible why would any pro wildlife shooter use DX? They could always just crop there image with an FX camera and still get superior results.

Something just does not sit right with me with these results and I wonder if others who have both FX and DX bodies are able to just crop there FX images and get better than comparable results to their DX bodies.

Sorry I could not add anything and did not mean to steal your post.

I would not judge the performance of the D7000 (or any DX camera) relative to FX from the initial images in this thread. Several reasons have been put forward why a 10-mile-away mountain isn't a great test target. We've all seen images in other threads here which illustrate the true capabilities of the D7000
