Which 1Ds? 1DX? 1D4? 3, 2? or 1Ds that full frame cameras?
I want real tests against say 1D2n and 1D3 and/or 1D4, i can let 1D2n go, but i am not sure i will let 1D3 go easily yet, i know 7D2 is almost better in many ways and newer camera and tech, but sometimes newer is not always better.
1Dx and 1D4, Romy and a few others have already posted accounts. Look for Liquidstone posts here on this board. ISO performance will be very close to the 7D and 70D, but the AF system sounds pretty wild.
