The Canon EOS 1D Mark III is a sturdily built professional DSLR with a 10mp APS-H (1.3x) sensor, 45-point autofocus, and 10fps continuous shooting. It's a fast camera that's great for sports and action- but it's more than capable of doing pretty much anything else (except for super high ISO shooting, since the ISO settings only go up to 3200). Compatible only with EF lenses, not EF-S. In excellent condition, with only the most minor cosmetic wear. Includes battery, charger, and a 16GB Sandisk Extreme CF card.
