Canon EOS DSLR Cameras - EF Lens Mount

EF Lens Mount

The bayonet-style EF lens mount is at the centre of the EOS camera system. Breaking compatibility with the earlier FD mount, it was designed with no mechanical linkages between moving parts in the lens and in the camera. The aperture and focus are controlled via electrical contacts, with motors in the lens itself. This was similar in some ways to Canon's earlier attempt at AF with the T80 and Nikon's 1983 F3AF (and to many of Nikon's more recent autofocus lenses), and other manufacturers including Contax (with its G series of interchangeable-lens 35 mm rangefinder cameras) and Olympus (with its Four Thirds System) have since embraced this type of direct drive system. It is a large lens mount compared to most of its competition, enabling the use of larger aperture lenses.
