Hi! I happen to have a very sick lens. The focus mechanism seems to damaged - overall the focus ring is quite stiff, and there are some extra stiff spots and some spots where turning the ring doesn't change the focus, as if it is disengaged for a little while. (I hope my dodgy explanation makes sense!)
So I think I need to take it to a professional repair place. Before I do, though, does anyone have any idea on:
- What is wrong with it?
- Can it be fixed?
- If I take it to a repair place, do check it out first, diagnose the problem, charge me for the diagnosis, then quote for the repair?
- What's it likely to cost to repair?
Actually, I have another lens that is showing similar symptoms, although very mildly. Oh, and it's all Canon.
