The EOS 5D is a 12.8 megapixel digital single-lens reflex  camera body produced by Canon. The EOS 5D was announced by Canon on 22 August 2005,^[1] and at the time was priced above the EOS 20D but below the EOS-1D Mark II and EOS-1Ds Mark II in Canon's EOS digital SLR series. The camera accepts EF lens mount lenses.

The EOS 5D is notable for being the first full-frame DSLR camera with a standard body size (as opposed to the taller, double-grip "professional" camera body style). It is also notable for its price, suggested at US$3299 sans lens,^[1] which set a significant new low price point for full-frame DSLRs; its only full-frame competition at the time was the Canon 1Ds Mark II, which cost more than twice as much.

On 17 September 2008, Canon announced the camera's successor, the Canon EOS 5D Mark I
