Canon 15mm Fisheye F2.8 Focus Problem

[ajabdeep]

Hello All,

I have about 5 year old 15mm Fisheye lens. i dropped it couple of times. nothing broke but kind stopped focusing with manual focus point selection. if i put my camera to auto focus select it focus at random spots. i am cps member and can send it for repair, but i'd like to know if  there is anything that i can do.  Thanks

Um... dropped it a couple of times? There is probably internal damage to something in the lens causing it to malfunction. So the only way to fix it is to send it in to Canon.
