The highest resolution sensor ever to be used in an EOS
Canon's newly developed, 16.7 megapixel full Size CMOS sensor captures more pixels faster, for no-compromise high-resolution photography. With a recorded image size of 4992 x 3328 pixels, and low noise levels comparable to the EOS-1D Mark II, the EOS-1Ds Mark II can create images large enough for almost any purpose, whether on location or in the studio. With ISO ratings of 50-3200, there's almost nowhere this sensor won't perform. As with its predecessor, the EOS-1Ds Mark II's sensor is full frame, meaning no focal length conversion factor-lenses will have the same angle of view as they would on a 35mm camera.
With RAW plus four JPEG file sizes available, from 16.7 megapixels down to 4.2 megapixels, the EOS-1Ds MARK II can be adjusted to conserve space on memory cards if large images are not the priority of the shoot.
