Bornshooter... That was really a helpful reply for Hector? Thanks!!!i do apologise buy a filter removal tool hector.
"This is why i dont use uv filters if the glass would have broke your lens would have been damaged anyway"
Hector...if you are not super handy and confident with tools...I think your best bet is to send the lens to Canon as some here have suggested. Unfortunate situation...be then you can rest easy and they can check out the lens too just to make sure that it is operating properly.
