Review (Summary): "... Besides upgrading to the concept of the 1D Mark II, naturally the image sensor is the main improvement of the 1Ds Mark III.

... The Canon EOS-1Ds Mark III offers you every possibility to capture the ultimate picture. The resolution is outstanding and you will be amazed as to what detail is captured in the picture. Also thanks to the massive dynamic range. High contrasts are captured without a problem, moreover at low ISO sensitivities. If you want to shoot at environmental light, the camera won't disappoint you. Noise is not a problem anymore, although there is still some improvement possible in the highest ISO level. As far as quality is concerned, I think we are reaching the top...."
