Pentax FA 50/1.4 back-focus

I will post up some photos later, but what can cause a lens to come out of focus? I have owned it for a few months, haven't used it a ton but it seems to be back-focusing quite a bit. It was spot on when I got it.

I'm assuming that Pentax Canada should cover this under warranty. I should have the reciept somewhere...


EDIT: From what I can tell my other two lenses (kit lens and the PDA 50-200) work just fine. The FA50 focuses perfectly in the viewfinder. Weird.
