My 3 year old dropped my Canon SX 280 HS camera (hope this is relevant) with the lens extended. After about half an hour trying must of the suggestions on this page I reached a new level of frustration. I tried swishing a piece of the paper round the gaps. A tiny piece of paper broke off and stuck inside. To solve this particular issue, I effectively bent the extended lens to create a gap so the paper would fall off, dangerous I know. Then I heard the click that made me think it was finally ready for the bin but hey presto it started working again!
