I have a Canon Powershot SX30IS and I keep getting a lens error. I was taking pics outside on a clear cold day in wintertime and my camera just displayed that message and shut down. I powered my camera back up, took a few more pics, and then the same message came up again. I have not been able to take a photo since. My camera will not even open to give me a chance to power it off. It will do this with the same error message. Is there anyway I can fix this myself, as the camera is about 6 years old?
