Acceptable autofocus speed and decent contrast
Slow and Servo easily fooled.

Given its place as one of the first Canon autofocus lenses, this lens does a decent job, on par with the FDn 35-70mm f3.5-4.5 (a lens I really like for travel). One shot autofocus works very well on sunny days with contrasty subjects. Servo struggles with objects moving towards the shooter, although is pretty good for subjects moving horizontally. Any series of vertical or horizontal lines gives it fits. Manual focus works well in these situations. Obviously, this is not a fast lens and dark spaces render the autofocus lens than ideal. Images are sharp (ish) when the T80 is set for greater depth of field. This is the easiest lens to find for the T80 among the three that were produced as it was sold as the kit lens for the camera. I also own the AC 75-200 f4.5 but have yet to test it. As the AC lenses cannot be used on any other camera it would not be wise to spend money on them unless you find a cheap T80. I got a T80 with AC 50mm f1.8 for $20US so it was worth it to have some fun.
