Take the memory card out of your camera and look at it. SD cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card. If the switch is already in the proper position, slide it fully the other way and then back again.
The most common problems in these small tiny cameras is the lens alignment. If you drop the camera with the lens extended this alignment will ****. If you are a handyman you can fix it by yourself by oppening it inside and realign/putting the lens in right position. Sometimes you can do that by forcing them to extednd manualy but that is very risky. If not handyman I recomand you to take it to a repair shop.
Is this a lens error or an error with the memory card? People seem to see this error for both cases. If it occurs while recording a video or taking a photo:
Save your photos & videos onto your computer, then reformat your memory card.
You need to use a card reader. Once the memory card is in the reader it will appear to your computer as another hard drive, and you can copy pictures to it as you would copy any other files.Bear in mind that if you've done any editing on the pictures then the camera likely will not display them.
"Lens error, restart camera". Unfortunately, restarting the camera (turning it off and on), rarely corrects this problem. Here are some troubleshooting steps that you can try that may (or may not) correct your problem. 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. Some of the later steps do involve some risk to the camera, so carefully weigh your options before deciding to conduct them:And here's a video summary of the steps:
Well make sure you focus the camera and without leaving the shutter buton click it.Dont let the camera re focus. Also View the the image from the view finder ( digital).If not reset the camera.
Over time it should dry. Chance of moisture in other parts of camera? Suggest removing batteries and not using at all until you are sure no moisture inside that could cause electrical damage. My Powershot fell in a river while hiking and simply let it dry out over a few weeks. The screen has internal blemishes, but that doesn't affect the photographs.
The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program, such as iPhoto on Mac or Windows Photo Gallery on Windows.
