Question about Canon PowerShot A720 IS Digital Camera

1 Answer

Lens error. Restart camera.

When I turn my camera on it beeps, then the screen says Lens error. Restart camera. I put in fresh batteries with no change. At first the lens did not retract but I gently pushed it back in. Since I did that I still get the same error message but the lens does not open up at all. The camera turns off by itself after the error message displays.

Lens error; restart camera


Try one of these two fixes, if they dont work for you follow the link below for further troubleshooting.

http://camerarepair.blogspot.com/2007/12/fixing-lens-error-on-digital-camera.html


Fix #1: Remove the batteries from the camera, wait a few minutes. Put a fresh set of batteries back in (preferably rechargeable NiMH 2500mah or better) and turn the camera on. If that didn't work, try pressing and holding the Function or OK button while turning the camera on.
Fix #2: If the camera's batteries ran down completely while the its lens was still open, the camera may show a lens error or not start properly when new batteries are installed. Remove the memory card and keep it removed, then install the new batteries. When you turn the camera on with the card removed it may come back to life, as this triggers a reset in some cameras. Error E30 (for older Canon's) means that you don't have a memory card installed, so turn it off, slip in the SD card and turn it on one last time

Canon IXUS 100IS - 'Lens error, restart camera' message


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 ... Unfortunately, many cameras that fall prey to this can only be corrected by professional repair. But, here are some things that you can do 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, they're worth a try:

Lens error, restart camera.


I had the same problem with my powershot and with the batteries going bad super fast. The way to fix it is to empty your memory card of all pictures then put it back in the camera blank. That should take care of the problem and should pro;long your battery life as well.

It has a lens error. Everytime the camera is turned on it beeps and clicks constantly. It eventually shuts off after displaying "Lens error, restart camera." on the screen.

I just had the same issue when one of my children drop the camera. I'm not wanting to break anyone's camera but I was able to open the lens cover and pull the lens out and then turning it on it retracted and worked just like it should.

Nikon Coolpix L4 Lens error


This has to be THE most common failure mode for a digital camera. Some common error messages that might show up on the LCD's of cameras with this problem include “E18 lens error”, or “lens error, restart camera”. Some cameras might show nothing at all, but merely make a beeping noise as the lens goes out, then in, then the camera shuts off. Sometimes the lens won't even move.

The problem is actually quite common throughout all camera brands. 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. Believe it or not, one BIG contributor to lens errors is using a camera case. Sand, gunk, case fibers, etc... accumulate at the bottom of the case. These materials love to cling to the camera by electrostatic build-up from the camera rubbing against the side of the case (especially those cases with soft fibrous intreriors). Once these materials work their way into the lens mechanism, that's all she wrote. I have many Canon's, and NEVER use a case for this very reason.


Fix #1: Remove the batteries from the camera, wait a few minutes. Put a fresh set of batteries back in (preferably rechargeable NiMH 2500mah or better) and turn the camera on.

Fix #2: Remove the batteries, then remove the memory card. Then install the new batteries, when you turn it on it should come back to life. Error E30 means you don't have a memory card installed, so turn it off, slip in the memory card and turn it on one last time.

Fix #3: Insert the cameras Audio/Video (AV) cable, and turn the camera on. Inserting this cable ensures that the camera's LCD screen remains off during the start process. Thus extra battery power is available to the camera's lens motor during startup. This extra power can be useful in overcoming grit or sand particals that may be jamming the lens. If the AV cable doesn't fix the lens error by itself, consider keeping this cable installed while trying fixes 4, 5, and 7 as a means to provide extra help to these fixes. But note that I DON'T recommend keeping the cable installed during Fix 6 as you may damage the AV port while tapping the camera. Reinsert the cable only AFTER tapping the camera.
