I have a Konica Minolta Dimage Z3. I have recently been taking a lot of pictures using the zoom. I wonder if that is the reason why the anti-shake symbol in the LCD screen is gone red. Seemingly, this is due to overheating, but I have had the camera switched off for a couple of days, and the symbol is still there, in red. Also, when I switch the camera on, the image shakes for a few seconds before stabilizing. Any ideas of what's wrong with it? Thanks!
