Wondering if any of you have heard of this. I've started to experience an intermittent problem with my 7D where the shutter will occasionally fire between two and six times with a single button press. Camera is set for "single" shot and no AEB enabled. Seems to occur mostly when I'm focused on objects that are close (18-24 inches) and then only once in a while. Annoying not because it impacts picture quality but because the unwanted Raw images take up a lot of space on my card. I consulted the experts at Camera West in Rancho Mirage CA because I was sure that I had inadvertently made some type of idiotic modification to a setting but they assured me all settings were OK. Naturally I couldn't duplicate the problem while in the store. Just wondering if any of you have experienced this issue.
I have the 7D and have never experienced this phenomenon.
A couple of things to try:-
Try to replicate the problem after each step above. If it still exhibits the problem:-
If the problem still occurs I would take it to an authorised Canon dealer who should be able to send it back to Canon on your behalf to be checked out. It sounds like it may be an issue with your camera. If it is less than one year old you should be able to get it fixed or replaced under warranty.
Once in a while, even in single shot mode, my finger get nervous : it "trips" and triggers a second or even a third shot, but 6 it's a lot ?!
Possibly there is a subtle mechanical problem with the shutter button that arises only in specific conditions (for example, does it occur more specifically in portrait or landscape orientation ?).
If you can do without your camera for the time it takes the Canon service to check it, I recommend you send it in. Otherwise live with it, since it doesn't seem like a major issue ?
