Except that mine went further, gave me some un-explained over-exposed shots, and then one of the aperture blades came totally loose and simply hung in the middle of the optical path. This stopped auto-focusing on my 10D, and a few shots later the "Err 99" message came up. Canon UK fixed it for me (~�70), and I now have an excellent light-weight lens when I want to travel light. (I know I could have bought another used lens for less, but at least I got myself a new aperture motor and a short warranty.) Hope you've got another lens you can use on your visit.
