Canon A-1 Camera Manual

Brief History

Released in 1978, the Canon A-1 was a groundbreaking 35mm SLR film camera that introduced fully automatic exposure modes to Canon’s A-series lineup. It was the first SLR to feature Shutter Priority (Tv), Aperture Priority (Av), Program (P), and full Manual (M) modes in a single camera, making it incredibly versatile.

The A-1 was marketed as a professional-grade camera, positioned above the Canon AE-1, which was geared more toward enthusiasts. With its electronic controls, LED viewfinder display, and robust build, the A-1 became a favorite among serious photographers looking for flexibility and automation.

It remained in production until 1985, when Canon began shifting toward their T-series and autofocus EOS system.
