I recently got an EF 50mm 1.8 lens for my EOS 60D. The automatic focus appears to be fine but turning the focus ring while in manual does not change focus at all. I've made sure that the lens is set to "MF" and I can see "M FOCUS" on my top display. I tried the lens on another camera and it behaves the same way.
