Canon's ultimate resolution DSLR of its era — 21.1MP full-frame with professional 1-series build.
The Canon EOS 1Ds Mark III launched in 2007 as Canon's highest-resolution professional DSLR — 21.1MP full-frame in the tank-like 1-series body. It was the studio and landscape photographer's choice when maximum Canon resolution was needed.
The 21.1MP full-frame CMOS sensor delivered the highest Canon resolution until the 5DS. 45-point AF with 19 cross-type sensors. 5fps burst. Dual DIGIC III processors. Live View added. 14-bit RAW. Outstanding dynamic range for its era.
1-series magnesium alloy body with integrated vertical grip. Dual CF card slots. 3-inch LCD at 230k dots. Full weather sealing. 300,000-cycle shutter. 1210g body only. The ultimate professional Canon body for resolution-critical work of its era.
Available used at mid-range prices — good value for a 1-series body. 21.1MP feels limited now but the pixel-level quality remains good. The 5DS R offers 50.6MP in a smaller body. For those wanting 1-series build quality at bargain prices. Check shutter count.
