Hi there everyone. I got a back-focusing issue with my FA 50/1.7. I've been ignoring the problem and using my other 50s (all manual) but recently I've decided I should get this thing fixed. I live in Toronto, so if anyone has any experience going about sending lenses to Pentax for repairing I would love to hear your advice. More importantly if anyone knows the price range for a fix like this, I would love to know that too Thank you !
