I let someone else use my camera yesterday, and upon getting it back, my autofocus no longer works right. I'm using the 14-42 lens that came with the camera, and there's only a very narrow window (only a few inches deep) that I can focus in properly. Otherwise, the camera doesn't seem to be able to focus on anything. Is this a sign of a damaged lens? Or is there some weird setting that has somehow locked my focus distance? My camera and lens are still under warranty, but since I am traveling at the moment, I don't have my warranty card and sales receipt with me, so if I need to repair it, I will have to pay. Hopefully I won't have to pay American prices for service in Indonesia.
