I downloaded the NEFs and opened them with CNX-D.

1. ISO64 shows a different focus point as the D810's, it's backfocused by comparison, it's clear if one looks at the green leaves on the right. This affects detail all over the image. D850 on the right. Better seen on original.

Another point: they used different lenses, on D810 and D850, not a good way to start a test.

2. ISO 6400 and 12800 are actually 25600 and 51200, so don't panic, IR will likely correct that soon.

But

IMO noise is mushier in D850 high ISO files, even turning all NR off, see the ISO25600 comparison with D810 (see original).

I can't say if there is an improvement or not in high ISO, looking at these I see just different character, maybe ACR will show a different result. I prefer clean, crisp noise, as it tends to disappear in printing and preserve finer detail. Here's ISO3200:

Looks slightly cleaner on the D850, but closer inspection in full size will show again that it's mostly an effect of the different character of noise with CNX-D.

I'm sure the bottom line noise after NR or downsizing will be better than the D810 given the higher pixel count and four years of sensor development. No worries. The detail retrieval is a rather large step up:



810 v 850
810 v 850
 
I downloaded the NEF files for D850 using NR, they have right ISO settings, then turned NR off manually for the comparison.

ISO 6400 on left, D810 on top. Open original size.

Just see a difference in noise character, but mostly similar results.

Thanks for posting this.. :-)

..stupid question on my part.. so excuse.. every NEF file that I run through Capture NX-D, I'd make sure to turn off sharpening, turn off noise reductions, turn off lens corrections.. for me, I prefer the "results" after these are turned "off".. just checking.. ;-)

..Cheers..

I downsized D850's files to D810's res and I was looking mostly at the visual noise performance, but certainly detail is a bit better, given the higher res, about 12% linearly. Downsampling to same final size may show a bit better detail, but you need a very high quality printer to get that visually.

For most users, differences, either in detail or in high ISO, will be irrelevant.

I think the D850's other features, like AF and speed, are more important. It seems that most of the effort re sensor tech was spent in being able to run 45MP very fast, to IQ or ISO.

I turned NR off, but not the standard sharpening, which was same on both, will check if that makes a difference re noise character and intensity. We have learned that a little sharpening is required with Bayer filter systems to get back to what would be considered "normal".

..thanks for the feedback :-) ..personally, I prefer when the sharpenings is turned down to "0" in the Capture NX-D, then to sharpen later on using another software, this is so to minimize the "jaggy's" from sharpenings.. ;-)

Edit, you are right, the differences are going to be more features.

I worked a bit with USM and Standard PC sharpening settings to see if I could get them close. It seems that the default sharpening applied by Standard profile works differently on both cameras. I then reduced the profile sharpening from 3 to 1 and applied USM with 30,5,0 on the D850's files. The results are now almost same, grain is similar in character now, see 6400 and 12800 ISO results, D810 on top.

I see a tad cleaner colors in the last comparison from D850, same lumina noise, but I doubt one would notice that in print, and moreover, no exhibition or wall-hanging frames will have side-by-side images from both cameras, so no one would ever be Abel to say which camera was used for an image.

Thanks for posting these results, and thanks for your work on this! :-) ..to many feel, printing is where the pudding is.. and thanks for sharing your experiences.. to say this, I'm glad to see so many varieties & models of cameras available.. each photographer / consumer, can choose & select which camera(s) appeases to them..

..from your results, I personally prefer the results from the D850 camera.. am looking forward to recieve mine.. and looking forward to shoot low light cityscape pics with it.. ;-)

..Cheers..

Here D850, at same res, pulls ahead, I'd say by a 0.5 stop or so, the 25K from D850 seems in between 12K and 25K from D810. This may be useful for those shooting in dire conditions needing high SS.

12K on left, D810 on top.
