It is an autofocus lens that I would assume is from Canon and made for the T80. However, years ago my wife bought me a autofocus lens for my T70 which is a Vivatar lens. It looks very similar to the one in the photo and as mentioned in an earlier post it was activated by a button on the side of the lens and was powered by four AAA batteries. It takes very nice photos and I still use it quite a bit, in fact it is mounted to the T70 as I type.
The Vivitar autofocus lens is, as the very first Canon FD autofocus lens, self-contained.
The three lenses for the Canon T-80 however are steered by an AF sensor-/controll system within the camera body.
