Question about Canon Normal EF 50mm f/1.4 USM Autofocus Lens
I have Canon 50mm f/1.4 USM. It just stop working in AF mode for auto focusing. It is hardly used
This lens should have a 1 year manufacturers warranty on it, and if my guess that the USM motor is burned out is true I would have it serviced by an authorized service technician. Before you do this though I would try cleaning the lens contacts to make sure it is communicating with the camera body. I of course am going on the assumption that you have tried other lenses on the camera body to make sure the problem is the lens and not the body. I hope this helps!
