Hi, this isn't a solution but I need an help: Some sand comes into optical so I opened the camera, clean the gears but after done I had problems to remount them in right position !!! If anyone can help me by clicking a photo of the gears near the zoom motor. Its six gears and it seems easy to remind...... how wrong idea ! Thanks, stefano

the same thing happened to me. I took my camera apart - just removing the case. I then operated my camera and it became "unstuck". now it works just fine. I put the case back on and all is just as before.

It's the focus lens gears. The often times get knocked out of alignment by an impact, or debris gets in there. This can be fixed, but Casio won't help. Hint...google my username. ;)

This is the lens focus gears. They are either knocked out of alignment, or debris has jammed them. The good news is it can be fixed....Casio most likely won't help. Hint...google my user name.

"lens error" will only be fixed by sending into repairs. 800-706-2534 and keep choosing option 2. Tell them you have a lens error and they will tell you where to send it.
