[edit] 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.
[edit] Mark II incarnation
The Canon EOS-1Ds Mark II supersedes 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).
[edit] 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.
