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 was a version of the popular AE-1 but without the shutter-speed priority auto-exposure mode of that camera. The AT-1 featured 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.
The accessories produced for the AE-1 also worked for the AT-1, including motor drives.
