The Canon AT-1 is a 35mm film SLR introduced in the late 1970s, using the Canon FD lens mount. It sat below the AE-1 in Canon's lineup of the period, offering centre-weighted match-needle metering rather than shutter-priority automation.

Sales data for the AT-1 is thin: a single recent UK auction hammer result in September 2025 closed at £110, which gives an indicative wholesale value but not a reliable range. Buyers asking what a Canon AT-1 is worth today should treat that figure as a guide only, since condition, working meter, and bundled FD lenses materially affect what the body sells for at saleroom level.
