I know many of you are photographers, and I wanted to pass on some info that may enable you to get a lot more use out of your camera. I discovered that some Canon Powershot S400 cameras have an internal communication problem that can make it difficult or impossible to turn on at times, and if it can be turned on, sometimes it's unable to take a photo. Canon realizes that this should not be occurring, and they'll fix the problem free of charge, with free shipping to their service center, even if the warranty period is over.

My camera had worked flawlessly for 2 years before it began to have this trouble. I'm so happy to see that Canon is giving it excellent after-sales support.
