Canon EOS-1Ds Mark II
Encyclopedia
The EOS-1Ds Mark II is a digital SLR camera body
by Canon Inc.
of Japan
. It was the top model in the Canon EOS
line of digital cameras until April 2007, with a full-frame 16.7 megapixel CMOS
sensor. The EOS-1Ds Mark II had the highest pixel count available in a 35mm format digital SLR at the time of its introduction until its successor was announced in August of 2007. It uses the EF lens mount
. The EOS-1Ds Mark II is a professional grade camera body and is large, ruggedly built, and dust/weather-resistant.
Being an autofocus camera, it has multiple autofocus modes and uses a 45 point autofocus system, and an option for manual focusing. Its viewfinder is a "fixed pentaprism
". It also has a 2", TFT
, color LCD. Its dimensions are 156 mm in width, 157.6 mm in height
, and 79.9 mm in depth (6.14 in × 6.20 in × 3.15 in). Its mass
(without a battery
) is 1215 grams (42.9 oz).
The camera's image sensor is a single-plate CMOS-based integrated circuit
, 24 mm × 36 mm in size; the same as 35mm film. It has approximately 17.2 million total photosites (16.7 million effective pixels in the final output). It uses a RGB primary color filter.
The shutter
is an electronically controlled focal-plane shutter. Its maximum speed is 1/8000 of one second
and it is rated for 200,000 actuations. Soft-touch shutter release occurs via electromagnetic signaling.
On August 20, 2007, Canon announced the successor to the Mark II: the Canon EOS-1Ds Mark III

Pentaprism
A pentaprism is a five-sided reflecting prism used to deviate a beam of light by 90°. The beam reflects inside the prism twice, allowing the transmission of an image through a right angle without inverting it as an ordinary right-angle prism or mirror would.The reflections inside the prism are not...
