A lens error can be caused by physical damage to the mechanism that controls the lens, or debris that is interfering with the operation of the lens.

In the event that your problem is due to physical damage and not just dirt or debris, you will need to take it to a local camera repair shop for troubleshooting-- though with most consumer digital cameras, labor and parts cost of a repair can easily exceed the value of the camera.

Lens errors are fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended...

Here's some things that you can do to try to correct it. They only seem to work for less than 50% of the lens errors, but if the camera is out of warranty, they're worth a try:
