I have a Cannon A520 digital camera that the lens doesn't open on unless done manually. The camera is used on a road construction project in the Oregon Coast Range. I take 100+ pictures a week. The environment can be damp. I've used a can of gas duster, but it has not been helpful. The lens is becoming difficult to open manually. Do yo have any suggestions?
Just to clarify, are you having trouble opening the protective flaps/barriers that cover the lens? Or are you having trouble getting the lens to physically extend out like normal (you have to twist it to get it out)?
- If you need clarification, ask it in the comment box above.

Common problem with automatic lens covers. I use a toothpick to manually open the lens with the camera on. The use some glue, small amount on the lens cover to glue it open. Then I would carry it in a carry bag.
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 are some troubleshooting steps that you can try that may (or may not) 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. Some of the later steps do involve some risk to the camera, so carefully weigh your options before deciding to conduct them. And by coincidence, here's me going through the steps using an A520 as an example in this video:
The lens has probably got something in the retraction mechanism that is stopping it retracting. This can be something as simple as sand or grit or as a result of a drop or knock. In most cases the camera will need to be stripped apart to remove the lens assy before it can be repaired. This is best left to a professional camera repair shop.
the 520's are notorious for lens opening issues... I've had a few and any dirt or moisture in the lens shutters, and they'll get screwy. Clean dirt with a little compressed air...not high pressure... Batteries... set the resolution a bit lower, avoid alot of flash and zoom and you'll get better battery life... it's part the 520...carry spare alkalines.. always.. K
hey guys. there is no solution that you can do it for yourself. the best solution i can give for you is take it to service centre. here in india we get charged nearly 1800rupees for servicing the lens portions.
