Description — Canon EOS-1Ds Mark III
The Canon EOS-1Ds Mark III centers on a 21.1 MP full-frame (35mm) sensor processed by a Dual DIGIC III engine, producing images at a maximum resolution of 5616 x 3744 pixels. Burst shooting reaches 5 frames per second, and the 45-point Phase Detection autofocus system — with 19 cross-type and 26 assist points — ensures reliable focus acquisition across the frame. The ISO range spans 100 to 1600, suited to controlled and well-lit environments.
The 3.0-inch TFT LCD at 230,000 dots handles image review and menu access, while an Optical Pentaprism viewfinder is used for shooting. Built from magnesium alloy and confirmed weather sealed, the body measures 156 x 159.6 x 79.9 mm and weighs 1,385g. Storage flexibility comes via both CompactFlash and SD card slots.
Lens compatibility is via the Canon EF mount, and six in-camera color profiles — including Standard, Portrait, Landscape, Neutral, Faithful, and Monochrome — offer rendering versatility. The NP-E4 battery is rated for approximately 1,800 shots per charge.
