The Canon AT-1 is a 35mm SLR film camera introduced by Canon in late 1976 as an export-only model. It shares the FD lens mount and many accessories with the AE-1 but is a match-needle, manual-exposure camera. Its viewfinder displays an analog needle for scene brightness, which the user aligns with an EV "lollipop" by adjusting aperture or shutter speed. The AT-1 uses an electronically timed shutter and is battery-dependent. It features a 10-second self-timer with an LED indicator. The AT-1 offers access to inexpensive, used FD-mount lenses in a body without extraneous features.
