I've noticed my Canon 100-400mm will not manual focus(the focus ring wont turn) i did drop the lens a while ago which made a small dent in the side of the lens. I rarely use manual focus so dont know if its hasnt worked since then,everything else seems fine when using auto focus i'm guessing maybe something broke inside which stopped it turning any idea's?
