I accidently "bumped" my 30D today just moving it on a table, but it was enough impact to jam the lens cover into the UV filter and break the glass filter. (It was kind of an awful sound hearing something rattling around when moving the camera, but at least the noise just came from glass trapped behind the lens cap.) I took a few quick pictures, and I don't think I did anything to hurt the camera or lens (17-85 IS), but is there any way to check it to be sure?
