If you ever get this, and have not damaged your lens in anyway, don't worry. It can be fixed. Usually w/o any parts. :eek: Casio Exilim cameras don't really have good dust/debris protection, and the focus motor gears are easy to get jammed up. I buy these on eBay all the time, and fix them. They also get knocked out of alignment easily if dropped.
I can tell you how to do it, if you're so inclined, or fix it for you. :D
