The EOS-1Ds is a full-frame 11.4 megapixel 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
.
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 filter
s 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.
superseded the EOS-1Ds as the top model in the Canon EOS
line. It has a full-frame 16.7 megapixel CMOS
sensor.
Its dimensions are identical to its predecessor. Its weight (without a battery
) is 1,215 g
(2 lb 10.9 oz
).
". 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.
is the third in the Canon 1Ds full-frame line. When it was released, it held the title of the highest resolution full frame (35mm) dSLR, with a 21 megapixel CMOS sensor. Since then, the Sony α 900 (24.6 MP) and the Nikon D3x
(24 MP) have superseded the EOS-1Ds Mark III in megapixel count.
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 color LCD.
