The Canon T80 is Canon's first autofocus 35mm single-lens reflex camera. It was introduced in April 1985 and discontinued in June 1986 and is part of the T series of FD mount cameras, and is not compatible with Canon's later EOS system and its autofocus EF-mount lenses. Instead, three special lenses, designated AC, were produced for the camera. Other FD-mount lenses can also be used, but without autofocus capabilities.
