The Canon AV-1 is a 35 mm single-lens reflex camera with an FD lens mount, introduced by Canon Inc. in 1979.
The AV-1 is very similar to the 1976 AE-1 but provides aperture priority autoexposure rather than the AE-1's shutter speed priority AE. The camera is not capable of fully manual exposure.
Canon's international distributors, particularly in the United States, had clamored for such a camera because competing brands offered mostly aperture-priority cameras and some preferred it.
