Too little time to post in depth right now. Saw and handled the D3 and D300 today and the new lenses in Tokyo. Also saw large sample prints comparing D3 to the 1D Mark 3. The D3 clearly had better noise o in the high ISO (1600 and 3200) 40" wide prints. Remarkably little noise. Prints were from in camera large jpegs. No prints from either Canon or CR2 or NEF files. I'm told there was no post processing done with any of the prints. The cameras are very quick and the the AF in Live View works very well but not as fast as when used like an SLR. The camerass were very responsive. The 14-28mm f/2.8 is sweet very little chromatic aberretion problems with that lens on the D3 at 14mm, even into the corners -- at least on the D3 LCD (we weren't allowed to male test shots onour own cards. No word on who is making the 23.9 x 36.9 mm CMOS in the D3 Met Bjorn Roslett too!
