The Canon AT-1 is a 35mm FD-mount single-lens reflex camera manufactured by Canon of Japan from December 1977. It was produced purely for export and was never sold in the home Japanese market. It is a version of the popular AE-1 but without the shutter-speed priority auto-exposure mode of that camera. The AT-1 features manual exposure only. This made the camera cheaper, as some consumers did not desire or require autoexposure and did not want to pay for it. A light meter is included, featuring TTL center-weighted average metering with a CdS photocell, and a match needle in the viewfinder. The accessories produced for the AE-1 also work with the AT-1, including motor drives. External links AT-1 at the Canon Camera Museum Photography in Malaysia (2000). Canon AT-1 Camera.
