Canon's flagship APS-H DSLR — 10.1MP with 45-point AF, 10fps, and dual DIGIC III processors.
The Canon EOS 1D Mark III launched in 2007 as Canon's flagship APS-H (1.3x crop) professional DSLR, designed for sports and photojournalism. It combined 10.1MP with a 45-point AF system and 10fps burst — the ultimate speed machine of its era.
The 10.1MP APS-H sensor prioritises speed and high-ISO over resolution. 45-point AF system with 19 cross-type sensors — fast and reliable for action. 10fps burst with full AF tracking. Dual DIGIC III processors. Clean images to ISO 3200.
Magnesium alloy body with full weather sealing. Dual CF card slots. Integrated vertical grip. 3-inch LCD at 230k dots. Full HD video not available — pre-video DSLR era. 1155g body only. 300,000-cycle shutter.
Available used cheaply. APS-H is a unique sensor size — 1.3x crop is between APS-C and full-frame. Known for AF issues at launch that were fixed via firmware. The 1D IV and 1D X superseded it dramatically. A piece of professional camera history at bargain used prices.
