Turn camera on iy says lens error and shuts down

Never remove or insert a memory card while the camera is turned on. Try removing the battery, waiting about 30 minutes, and then putting in a freshly charged battery.

Never remove or insert a memory card while the camera is turned on!!!!!!

Most of the time, when a camera asks to shut down there is a problem with the camera. Could be the lens can't come out complete or other, almost invisible things. Even the battery can be a bit low, so as soon as it wants to make the camera ready to "shoot" the voltage goes low. Lots of cameras, will go off then. If you can't find any obstruction on the lens, please charge the battery and try again.

Lens error happens during the lens guide pin wrong movement. Please try these below and let me know.
1. Ensure batteries are fully charged & clean the battery connector point in side the battery compartment.
2. Look carefully between the lens and the camera body for any sand, dirt or any damaged etc.
3. Try turning the camera with the lens facing down and shake to dislodge anything stuck
4. Try removing batteries and memory card, wait 5 minutes and refit the battery only.
5. Now turn on camera( with out card ) and see ,if working then fix the memory card & again turn on the camera. If working then fine . Otherwise format the memory card and fix back in camera again & try. Make sure before format the memory card take a back up all photos in your computer then format. If no luck then reset or restore the camera setting by pressing Menu key for 2 sec .. in not done the press both Menu & self time key for 2 - 4 sec.

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:

Press the "MENU" button and navigate to the reset command and reset the camera. That may get the camera to function properly.

This is probably THE most common failure among digital cameras. There's a halfway chance of fixing it yourself, described here: http://camerarepair.blogspot.com/2007/12/fixing-lens-error-on-digital-camera.html

The same thing happened with my camera, I gave it to a freind for her husband to look at it. He said when turning on face the lens side down (to the ground) when turning off hold lens side up right (to the sky). this worked for mine. I don't know if he did anything else to it but when I zoomed I got lens error. I did what he said and it took several tries but it did work... please post if this helps you.

My Canon A75 has the EXACT same problem. I have always handled it with care. When I was taking photos with it, the camera suddenly started shutting down without a low battery warning. It just started shutting down, but it stopped with the lens still sticking half way out. Like yours, the top green light flashes when I try pressing the power button. Any ideas?
