disappointing results at ISO 100:
horizontal banding appears to be entirely removed, this is good, and will help make ISO look better and get less badly clumped chroma noise and all but vertical banding appears to be zero improved and it shows up enough that I don't think you gain any usable amount of low ISO DR back compared to the 5D2
so for low ISO I'm not sure the removal of horizontal banding alone will really help usable DR any since the vertical sticks out to the eye just as much, maybe here on there on parts of the image it might help
5D2: 15760,1024,6.1 AU,3.8 8MP normalized ADU, DR - 11.2 , DR8MP - 11.9
5D3: 15309 (maybe the channels were still not quite blown though?),2048, 6.6 ADU, 6.4 normalized to 5D2 6.4 and then to 8MP 3.96, DR- 11.0 DRto5D2 - 11.0 DR8MP - 11.7
and let us say WP should be 15760 instead then DR8MP - 11.8
and let us even say it should be max 14bit 16383 - 11.8
so I actually get fractionally worse DR than for the 5D2, but it's for all intents, the exact same, within copy to copy variation and well within any difference you'd be able to notice
Sad to say but even the DX D7000 handily beats the latest Canon FF for DR, and not by a little. The D800, at 100% view, full 50% MP advantage may beat it by 2 stops, maybe even 2.5 usable stops.
I did not expect this at all.
(the high iso side of things should turn out more favorable though, most likely)
LetTheRightLensIn thanks for your time. Thanks for akiskev too, for providing the raw files !
So, from my understanding, these new measurements with lens cap on/off confirms the ones that you did using the masking area ?
I am disgusted with the results. Will look at DXO measurments when out, but I am afraid that they won't be significantly different from yours.
Do you confirm that DR has improved @ the high ISO's ?
