Would it be possible to implement some kind of lock mechanism for the buttons on the back side of the camera?
Something like mobile phones have, when you press 2 specific keys and all the buttons get disabled.
I sometime use my A720IS with just one hand wearing glove, and it often happens that I unintentionally press one of the buttons on the back side of the camera, resulting in ... turning flash on, switching to macro mode, going to alt mode, etc.
But all I need is just shutter button and zoom, everything else I can preset before.
It would be nice if I could lock/unlock all the buttons by pressing direct print btn+delete btn together for example (or anything else, best if it would be possible to lock/unlock it by one hand as well). Maybe this feature could be useful for others as well if they want to use the camera in some "difficult" situations.
