Lense error my camera work well, but it does not open because lense error occur

The L105 works with SD cards. Make sure you're not using an SDHC card. You need to use SD cards, 2GB and smaller.

Unfortunately, many cameras that fall prey to lens error problems can only be corrected by professional repair. But, here are some last resort troubleshooting steps that you can try that may correct it. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty (or repair cost approaches that of the camera), they're worth that try.

More info needed.
Does the camera tell that a lens error has occurred?

lens strip is crack

The problem is
1- some dirt somehow got on the outside of the lense. After it was retracted fully in, it prevents the camera from opening again. When you turn it on, if it opens a little bit, try to pull it out NOT too hard and let go a few times. If it opened, clear the outside of the lense. Your camera should be back to normal.
2- If you droped the camera, you probably damaged or dislocated a mechanical part of the lense. You may have to take out the lense by unscrewing it and inspect it for damged parts or disconnected cable. Make sure clean the lense and test it by moving it in and out a few times, before puting it back on the camera.

Good luck!!!!!!!

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:

I have a solution for Nikon coolpix S5/S6. You can try my document "nikon s5 s6 lens cover error repair.doc"  uploaded on site

The "E18" or "Lens" error message indicates an error that involves the lens unit or lens cover.
This error may appear where the lens is prevented from properly extending or retracting such as, for example, when pressure is applied to the lens or the area surrounding the lens while handling the camera. The error may also be displayed if the lens unit/camera has been subjected to an external shock, or if a foreign substance (i.e. liquid, sand, dirt) enters the camera. Solution
Check the following when you operate the camera to avoid applying pressure to the lens and surrounding area:

• Hold the camera so that your fingers do not touch the lens unit when you are shooting.
• Make sure the camera is off before the camera is placed back in the case. Exercise caution to ensure that the camera does not accidentally power on while the camera is stored inside the case.

If you cannot clear the error code by turning the camera off and then on again, or if the error code is displayed frequently, a camera malfunction may have occurred and might require service

I had the same problem with my Nikon coolpix camera. Fortunately, I found a very strange solution from google.com :

"Hit the camera on the palm of your hand a few times (hit the side of the camera , not the lens). Try it slow at first, if it does not work try to hit it harder (but gently). "

I'm not sure if it will work with an Olympus camera and if this is a permanent solution ( a co-worker borrowed and lost my camera after a few months!!) . Also, there is a risk that you will permanently damage the camera. If your camera is under warrany send it for repair.

Good luck!

Sorry to say but a lens error actually is a problem that you cannot fix at home. When a lens error occurs, the motors inside that make the lens retract and protract were some how damaged, usually caused if the lens try coming out when you have it in your pocket or against a surface so it cant fully come out. You will have to send the camera in for service and you can do that by calling 1-800-706-2534, option 1.
