My camers is stylus 500 but this was nearest...

dropping of camera, especially on the lense side, gives damages to the lense barrels and their pivots. The moving barrels have small pin like projections which move into the grooves cut into the exterior barrel. when dropped either these pins get broken or they come out from the grooves due to the heavy jerk. If disaligned these can be set back to their normal position without much labour charges but if broken the whole assembly is replaced thus causing lot of payment.
