Cameras with the EF-S mount are backward compatible with the EF lenses and, as such, have a flange focal distance of 44.0 mm.
Are USM lenses worth it?
Ring-type USM is really superior to what else is out there. Unfortunately is comes at a price premium, so I know that all of my lenses will not be L’s. I am very happy to own an L, though, because it is so fast and quiet, it’s almost like magic when it works.
