After looking at some professionally developed test-images I can give you my first thoughts on the image-Quality of the D800:
100% viewing:
- no discernible difference between ISO 100 and ISO 200 regarding noise. There is some extended dynamic range to be expected when dropping ISO to 100 but that is another test.
- at ISO 400 you see signs of noise creeping in
- ISO 800 and 1600 still good enough for me pixel-peeper. Will not hesitate to use ISO 1600
- ISO 3200 would be just so-so for me, things start to go downhill. But some NR-tweaking salvages quite a bit
- ISO 6400 is looking ugly at 100% viewing (=pixel-peeping) with some strange bleeding
50% viewing (still 9MP resolution):
- I could tell what was ISO 400 and what ISO 200, but barely
- ISO 800 is fine, cannot complain
- ISO 1600 is only slightly worse
- ISO 3200 looks acceptable for me
- ISO 6400 would be acceptable too noise-wise if it were not for the bleeding of colors/light into darker areas
------
Oh and b.t.w.: D800 started to turn up at dealers. Let's see how many are claimed by NPS-members and how many will be delivered to the unwashed masses (like me)
