I. OVERVIEW 3
The Canon EOS-1Ds Mark III is a new, top-of-the-line, professional DSLR autofocus
camera with a 35mm full-frame, 21.1-megapixel CMOS sensor. It was developed in
parallel with the totally new EOS-1D Mark III, so the cameras are similar in many
respects. For example, the operation procedure, LCD monitor, menu functions, and
playback functions are all the same as those of the EOS-1D Mark III.
The main differences reside in the 35mm full-frame sensor and related features of the
EOS-1Ds Mark III, such as the viewfinder optics and the top cover, although other dis-
tinctions will be made in this white paper.
When the EOS-1Ds Mark III is compared to the camera it succeeds, the EOS-1Ds Mark II,
the differences are much more substantial. The new camera has higher resolution,
better image quality (from 14-bit D/A conversion vs. 12-bit, and DIGIC III vs. DIGIC II),
