Says lens error restart camera yet my lens will

Hi, your lens has probably been damaged , usuallly by dropping or bumping , or sand or some other particle may be jamming it. Try using a piece of photo film ( exposed negative) to search for anything that may be stuck in the lens where it telescopes out. Another "fix" is to firmly bang the corner of the camera case into the palm of your hand quickly after pushing the power button.This may loosen the jam
