Rather than hijack one of the existing threads-I thought I'd start another. Do any of you professional photographers have any tips for lens and sensor cleaning?
My wife has a Canon 20D and lately all of her pictures have the same spots in them. I think her lenses and sensor are dirty-but I'm afraid of making the problem worse with my shop vac. Any suggestions?
I'm probably using the wrong terminology-I'm referring to the mirror you see inside the camera body when the lens is removed. I think that part (or something else internal) is dirty, as there are similar spot patterns even after switching lenses.
