Canon FL lens mount

Canon FL refers to a lens mount standard for 35mm single-lens reflex cameras from Canon.

It was introduced in April 1964 with the Canon FX camera, replacing the previous Canon R lens mount.

The FL mount was in turn replaced in 1971 by the Canon FD lens mount.

FL lenses can also be used on FD-mount cameras.

Many mirrorless interchangeable-lens cameras are able to use Canon FL lenses via an adapter.
