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

Main article: Canon EOS-1Ds 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The Canon EOS-1Ds Mark II superseded the EOS-1Ds as the top model in the Canon EOS line.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 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

Main article: Canon EOS-1Ds 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 By September 2008, the pixel count for a Full-frame digital SLR is only superseded by the 24,6 megapixel Sony α 900, which was announced in september 2008.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.
