An image sensor or imager is a sensor that detects and conveys information used to make an image. It does so by converting the variable attenuation of light waves (as they pass through or reflect off objects) into signals, small bursts of c ...

Image resolution is the detail an image holds. The term applies to digital images, film images, and other types of images. "Higher resolution" means more image detail.
Image resolution can be measured in various ways. Resolution quantifies how cl ...

Mark II
The Canon EOS-1Ds Mark II
The EOS-1Ds Mark II is a digital SLR camera body introduced by Canon Inc. in 2004. 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 high ...

Mark III
Released in December 2007, the EOS-1Ds Mark III was the third and last of 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. More recent camera models from various manufacturers now exceed this.
Compared to the Mark II, the Mark III added several new features, such as integrated sensor cleaning, Live View (an electronic viewfinder mode) and a larger 3.0" primary color LCD.
The EOS-1Ds line was discontinued in mid-2012 with the introduction of the EOS-1D X, a full-frame body which merged the previous EOS-1D line of high-speed professional bodies with the EOS-1Ds line.
