For point and shoot cameras, if you drop the camera while its on (lens extended) and the lens get banged, it if it won't retract, there is a good chance that its a goner, having extensive experiences with all sorts of point and shoots, if you can twist it to break it free or push it, the AF (Autofocus) system may not work as well and may not focus on anything at all. From here, you can do one of two things:
* If its a fairly new camera, repair it, but the repair may cost just as much as the camera itself
* or buy a new camera, because, like I said before, the repair would cost just as much as the original price.
