I put it up against the GH3. Stock settings on both. Iso 200.

Just thought I'd add my opinion to this topic re the D7100. I bought this camera a couple of days ago after lots of forum reading/viewing footage and comparing what's available and at what price. I've owned a GH2 (donated for the work done on the hack) and a 5D MK3 (which I returned after several days testing). I have to say that I'm very impressed with the footage from the D7100, IMO the footage is very similar in detail to the GH2. One thing I've noticed re the detail is the lower amount of 'mosquito noise' present in the highly detailed parts of an image, the GH2 footage was indeed highly detailed but IMO was also a little too clinical, the D7100 footage has plenty of detail without any post work and it seems to be 'cleaner' around all the highly detailed areas of an image. The issue with noise and banding IMHO is being blown out of all proportion, I have an FS700 which produces very clean video BUT, if you screw with the settings too much you can destroy the image. The D7100 IMO is VERY sensitive and I think it's comparable to the 5D MK3. bringing-up the black level to fish-out detail in the shadows will produce noise that ordinarily wouldn't be an issue, in my tests (under 'regular' lighting conditions) the images from the D7100 are very clean indeed. At low ISO settings the images are totally noise free BUT, and that's a big but, if you pull up the black level too much you will start to see noise/banding. I would also add that under VERY, VERY low light conditions you can see noise in the image even at ISO 100 BUT again the noise is very low (all things are relative) and you would be asking way too much of a £1000 camera to perform well in such low light conditions. In low light or anything higher the images are very clean indeed, at ISO 1000 there is only a small amount of noise and I'm comparing this full size ENG broadcast cameras. At higher ISO's watch you're white balance setting, this has a dramatic affect on noise levels, I found that taking a proper white balance (as opposed to using any of the presets or the auto WB) produces the best low-noise images. BTW, the colours are fantastic and overexposed areas of the image seem very well controlled...

By DxO's ratings standards:

Nikon D7100 = 83 score

Nikon D800 = 95 score

Panasonic GH3 = 71 score

Canon EOS Mark III = 71 score

They might be distracted by the cadence of the GH3. The D7100 looks sharper in some parts of the image like the shadows and the GH3 sharper in others like in the small print which will be handy if your shooting a film about typography.

It sharpens up just fine

I wouldn't shoot @ 640ISO, it's too noisy, 800 is a lot cleaner. Neutral with the contrast down on the Nikons is a lot flatter than neutral with the contrast down on the 5D, it's almost log. Neutral with contrast on 0 or Standard with the contrast down has a lot less noise but is still quite flat. The sharpness needs to go down a notch, it's starting to halo. It's pretty close to the GH2 post sharpened.

Here's the screen grabs from my sharpening test I tried 3 lenses, 3 picture profiles, IPB, and ALL-I codecs and I couldn't get the 5D to sharpen up as well as the D5200. I post sharpened both in FCPX to the same level. In camera sharpness was 0 on the 5D and 1 on the D5200 which are the optimum settings for each camera before they start to show halos/fringing. I shot the D5200 with a 35mm Summicron-r and the 5D with a 50mm Summicron-r, 60mm Elmarit-r, and a 90mm Summicron-r and they had almost identical sharpness. All lenses were @ f/4 and both cameras @ 100ISO.

Pretty much the same banding people were complaining about with the D5200. I'll do some tests and see if Neat Video can get rid of it. It did well with the flickering from artificial lighting on my GH2.

@Aria here is a frame grab shot at 1600 iso f4 1/50th, PC set to -3 contrast +2 sharpness @ 24p, high in DX mode. Look in the black area for the FPN. It is much more pronounced in motion. BTW the 1.3 crop mode is very soft and kind of looks like the rez of the d5200.

After a month of testing and use I returned my d5200 and replaced it with a d7100 today. First impression is that the d7100 has better resolution. I would say about 15% more rez. The moiré and aliasing are non existing with the video I shot indoors. But I still see the horizontal fixed pattern noise in the blacks at all iso levels and in M an S modes, using several in camera and custom picture profiles, along with several good Nikon and Sigma lenses. I can also see the FPN on the HDMI output with my Cineroid EVF and on my Panasonic and LG screens set to 1080p. This really sucks because it would no doubt be outputted to any external recorder that I may want to use. The FPN was one of two reasons for returning the d5200, plus its poor overall resolution. I had such high hopes of moving into an APS C size sensor beyond using a GH2 or GH3.

I've found 1 sharpness to be the best setting on the D5200, any more than that and the edges start to look a bit artificial. I suspect the D7100 has the same Toshiba sensor without the OLPF.

A lens cap ISO noise test would give me a better idea if it's the same sensor.

We've measured the rolling shutter on the D5200 @ 22.4ms.

Got mine on Monday, and really, the colors are amazing! In photos at least. And the sharpness will blow you away! A sharpened JPG actually came out to a bigger file size than its RAW image. :3

I'll be doing video tests this weekend, but from what I can see, it's definitely better than the D7000, and I haven't seen much difference between 1080p, 720p, or interlaced/cropped versions as far as quality. Compression artifacts are still there, so you can't sharpen too much. I'll have to find the best in-camera Sharpness setting during testing.

If anyone wants me to do any specific tests, let me know. Here's what i have set up to do right now, in no specific order:

1. Moire test
2. HD resolution tests
3. Sharpness tests
4. LPowell's gamma setting tests
5. Jello test
6. Codec stress test
7. Low light test
8. Contrast detection AF tests
