The
Canon EOS 650 is a
35 mm single-lens reflex camera. It was introduced on 2 March 1987,
Canon's 50th anniversary, and discontinued in February 1989. It was the first camera in Canon's new
EOS series, which was designed from scratch to support
autofocus lenses. The EOS system featured the new
EF lens mount, which used electrical signals to communicate between the camera and the lens. Focusing and aperture control were performed by
electric motors mounted in the lens body. The EF mount is still used on Canon SLRs, including digital models. Canon's previous
FD mount lenses are incompatible with EOS bodies.
