I had the same problem with my ef 50mm 1.8. I used it on a cold day and broke off one of the internal gears. I used it for almost a year before I got the guts to take it apart and fix it. There are instructions online on how to take it apart, scary at first but not that hard overall. I used a small drop of crazy glue on the gear, put it all back together and just like new.
