(DSLR-)industry starting at EF 24mm f/1.4 USM L all the way up to the EF 200mm f/2 USM L IS.

Thanks to the usual ring-type USM drive the focusing speed is very fast and near silent.
Full-time manual focusing is, of course, possible in one-shot AF mode. The lens has a rear
focusing system so the front element does not rotate.
