Canon EOS-1DS Mark III vs Canon EOS-1D Mark III
The EOS-1D Mark III is the yin to the EOS-1Ds Mark III's yang; it's the same camera on the outside, but on the inside it's built purely for speed, with half the resolution but twice the frame rate. We thought it would be interesting to see how the two compare - even if they are so obviously aimed at very different markets.

The 1-D Mark III is no slouch when it comes to resolution but it can't quite match the 1-Ds Mark III (and is showing slight signs of moiré on the face of the Martini bottle).
