The EOS-1Ds is a full-frame digital SLR camera body formerly made by Canon, released in the spring of 2003. Its dimensions are 156 mm in width, 157.6 mm in height, and 79.9 mm in depth. Its mass (without a battery) is 1,265 g.

Functions

Being an autofocus camera, it has two autofocus modes, and an option for manual focusing. Its viewfinder is a glass pentaprism. It also has a two-inch, thin-film transistor, color liquid-crystal monitor with approximately 120,000 pixels.

The camera's image sensor is a CMOS-based integrated circuit with Bayer filters for RGB color detection (Canon calls it "single-plate", in contrast with three-CCD sensors). It has approximately 11.4 million effective pixels. A non-removable optical anti-aliasing filter is located in front of the image sensor.

The shutter is an electronically-controlled focal-plane shutter. Its maximum speed is 1/8,000 of one second. Soft-touch shutter release occurs via an electromagnetic signal.

Mark II

The Canon EOS-1Ds Mark II superseded the EOS-1Ds as the top model in the Canon EOS line. It has a full-frame 16.7 megapixel CMOS sensor (the highest pixel count available as of 2006 in a 35 mm-equivalent digital SLR). The EOS-1Ds Mark II is large, rugged, waterproof and dustproof.

Its dimensions are identical to its predecessor. Its weight (without a battery) is 1,215 g (2 lb 10.9 oz).

Upgraded functions

The Mark II has an increased number of autofocus modes, and retains an option for manual focusing. Its viewfinder is a "fixed pentaprism". The two-inch, TFT, color LCD has been upgraded to approximately 230,000 pixels.

The camera's image sensor is a single-plate CMOS-based integrated circuit. It has a higher density of photosites - approximately 17.2 million total (16.6 million effective pixels in the final output). It has a RGB primary color filter and non-removable low-pass filter, like its predecessor.

Mark III

Released in December 2007, the EOS-1Ds Mark III is the third in the Canon 1Ds full-frame line. At release date, it was Canon's most advanced digital SLR and the world's highest resolution Full Frame (35mm) dSLR, with a 21 megapixel CMOS sensor. By September 2008, the pixel count for a Full-frame digital SLR is only superseded by the 24,6 megapixel Sony α 900, which was announced in september 2008.

Compared to the Mark II, The Mark III adds several new features, such as integrated sensor cleaning, Live View (an electronic viewfinder mode) and a larger 3.0" primary colour LCD.
