The D810 looks pretty clean, the D750 seems to have some color issues. It may be because of some nasty settings, but to me it looks like the D750 is skipping rows (it has more horizontal resolution than vertical resolution, and only one set of bars shows that nasty color issue).

The D810 may be the best camera right now for people who care a lot about stills and also a lot about video (the stills from my a7s are great, but if you need AF then you have to get native lenses and there's a very limited range available, the past weekend a photog friend decided to stick with his Nikon D3s because he can't work without a fast 85mm; btw, D3s and a7s are exactly the same in terms of noise in RAW stills, according to dxomark and to our own tests).

That's interesting. It is a 12 megapixel full frame sony sensor after all. It might actually be the same.

But I do remember Sony saying that they sell sensors and keep some exclusively to sony cameras, and they gave the a7s sensor for the example.
 
Wondering how the 7100/5300 stack up? The 7100 is still my go-to for the luscious look, seems you have to go BMC to beat it on the sub $2k end.

This week's 7100 grab: Apparently Ms. Harris thought the lights were a bit hot and they dimmed them when we started rolling so things went a little, umm, warm (tunsgten flexipars). OLD push-pull 80-200 AF-D. Damn, that lens has some mojo. This is video, not a still.

I am REALLY REALLY hoping the Samsung NX1 blows me away...

From what I read, slashcam tested the D750 at photokina show by bringing their chart!!!!!!! If this is the case, I cannot see it as a real test.
 
@Ebrahim Saadawi: I don't think it's the same sensor, the one in the a7s has more DR and I would think it was designed with readout speed as a priority (so that the full sensor can be read at video frame rates)

@Michael Carter: OP updated to include D7100 and D5300 :)
(they are probably using different sharpness settings, slashcam doesn't usually talk about these details)

@DanielVilliers: mmm... that's not ideal... let's see if they get a better result when they test it in-house
 
I wish Nikon would put the 12mpx A7S sensor in a D810-esque body. Would make for a near ultimate sports camera. The D750 looked like just the camera I was waiting for - then I discovered it has no dedicated AF-ON button :(

Even exposure across the tests would be nice as well, popping the whites in a chart like that always looks sharper to me.

Samuel strangely, on Dxomark the A7s sensor is in the 13 stop range. It sure sound a bit strange because most if not all the latest Sony exmor sensor are in the 14 stop DR range. They do put it as the No1 in low light performance.

What is annoying is that the latest D810 and better yet D750 seems to be very capable video DSLR. Even eoshd had to change is anti Nikon tune when he tested the D750. Unfortunately his test are very subjective because even if his video is very very nice there it is only 60p and not one lock shot that we can really judge sharpness etc. But I guess to change is opinion it must be very very good camera. From his conclusion it is very sharp very close to the A7s in 1080p, very good DR and low light better than 5d3. I would have liked a more scientific or at least some side by side to judge the camera.

From the very very postive feedback comming from the photographic side and the video also but from limited source, it might be the best hybrid camera.

From Dpreview forum it seems that it is a non issue as you can customise the button in 5 minutes for the lack of AF-on button.
 
* I haven't tested it on my a7s but other sites have also found just 13 stops of DR in RAW stills mode. It seems the bigger pixel means an increase in readout noise that is bigger than the the increase in full well capacity (i.e. with current tech the optimal pixel size in terms of DR is smaller than what the a7s has; but you need bigger pixels to fill a big sensor and have fast-enough readout speed for full-sensor readout at video frame rates).

* The D810 looks pretty nice, but still it doesn't have such a great codec, or a profile that can compare to slog2 in terms of DR (it seems the cine flat profile is not any wider than the usual picture profiles). I would consider it the best option for people caring a lot about both stills and video, but since I care only about video, the a7s is better for me.
