Phase One P65+, IQ160, and especially the IQ180 meet all three requirements.
IQ180 with 5.2 micron sensor is very unlikely to show moire (I never say something like moire proof since even a Canon with a strong AA filter or the human eye can see moire), is full 645 frame and can shoot up to ISO3200. The P65+/IQ160 does so at 15mp with final print detail in a 4:3 image comperable to a 5DII. The IQ180 does so at 20mp, but we have not done direct comparisons to other cameras.
I'm considering that legally binding :-) and will expect your order Monday for one of each.
From the road
I knew it!
Is there a 3200 iso studio shooting sample somewhere in the internet from that beast? and to be fair, downsampled to the size of a 5D2 or D3x. I do not get what's the mecanism involved that reduces in-sensor the number of pixels at those sizes. The why.
And an outdoor shooting in a city with available light at night would be great to check also at 3200.
You're lucky that Simon is not interested in motion imagery.
