I think my 50mm is on the way out, for the 2nd time!!!!!! 
I had it fail just after the warranty expired but after a bit of to-ing and fro-ing of emails Canon agreed to fix it "as a gesture of goodwill". I've now had it just over 3 years and it's started freezing up on me, and then being rather noisy as it grates back and forth trying to focus. I'm so disappointed. I wont bother sending it in for repair, if and when if finally goes completely kaput. I'll be looking for another brand to replace it with.
Just had to have a little vent.
Any recommendations for a replacement. I've heard Sigma is good, IF you get a good copy, I dont know how true this is.
