The EOS 5D is a 12.8 megapixel digital single-lens reflex (DSLR) camera body produced by Canon. The 5D has a 35.8 x 23.9 mm full-frame CMOS sensor with 13.3 million pixels (12.7 megapixel effective). The very low pixel density of only 1.5 megapixels per square centimetre, combined with the redesigned DIGIC II image processor, provided significantly lower noise at all ISO sensitivities than any other consumer camera on the market. This position was only challenged by the release of the Nikon D700 nearly three years later. ISO speeds from 100 to 1600 are provided, adjustable in 1/3 steps (ISO can be expanded to L: 50 or H: 3200 with a menu function).
