The EOS-1Ds Mark III is a digital SLR
camera body
by Canon designed for professional photographers. The Canon EOS 1Ds Mark III is successor to the EOS-1Ds Mark II
and was announced in August 2007. The camera features a full-frame 21.1 megapixel CMOS
sensor with 14 bit A/D converters for a total colour depth of 16,384 tones per pixel. It features a three-inch (76 mm) LCD screen, capable of "Live View," and dual DIGIC III processors allowing it to shoot at up to five frames per second.
The EOS-1Ds features many technologies first seen in the Canon EOS-1D Mark III
, such as the 63-zone exposure metering, 19 cross-type auto focus system, a 3.0" LCD with Live View mode and EOS Integrated Cleaning System.

Auto focus
The auto focus system includes 19 cross-type sensors at f/2.8, spread across the AF area. There are 26 more assist points. The camera features an AF-ON button.LCD and live view
The back of the camera has a 3 inches (76.2 mm), 230K pixel LCD monitor, larger than the 2.0" display of the Mark II. Live View is a mode which uses this LCD as an electronic viewfinderViewfinder
In photography, a viewfinder is what the photographer looks through to compose, and in many cases to focus, the picture. Most viewfinders are separate, and suffer parallax, while the single-lens reflex camera lets the viewfinder use the main optical system. Viewfinders are used in many cameras of...

Firmware update
Canon occasionally releases firmware updates that fix bugs in the camera's firmware. The updates are available from the Canon website. As of May 2010, the latest update is version 1.2.0.Reliability
Canon has rated the shutter durability of the Canon EOS-1Ds Mark III and Canon EOS-1D Mark III at 300,000 cycles, significantly more than other EOS cameras. The 1Ds Mark III also has a new EOS Integrated Cleaning System that removes dust automatically. The camera is weather sealed against moisture. The camera beeps if the door is opened while images are being written.As of 20 February 2008 there are reports of some cameras having misalignment between the image sensor and the viewfinder/prism assembly. Canon is reported to have acknowledged the problems and is correcting affected cameras.
