My 50mm f/1.4 is at the repair shop

And I'm extremly sad about it. I bought it 4 months ago - it has, on three occasions acted weirdly, but not enough for me to do anything about it. However - two days ago the focus wheel got more and more unresponsive and by the evening there was almost no connection between the focus wheel and the focus, nor between the auto focus engine and the focus.
