Has anyone had a shutter serviced by Canon on an EOS? I have an EOS 10, which has fallen victim to the oily shutter phenomenon. There's a bumper which, after a time, deteriorates and turns into a tar-like substance that gets all over the shutter blades. (70% of my honeymoon photos were only the bottom half of the frame because the shutter didn't properly open.) I've tried cleaning the shutter with isopropyl alcohol and a paintbrush. This dissolves the muck and now the shutter opens all the way, except on the first go, ie if you leave the camera for a few minutes and fire off a few frames, it still sticks shut on the first frame, then opens all the way on subsequent frames. What I really need to know is whether anyone has paid Canon to fix this problem, either by cleaning or replacing the shutter. If so, how much did it cost? Canon charges A$75 just for a quote, so if it's going to be prohibitively expensive I'd rather put that money towards a new (used) body. I need a ballpark figure on what the repair would cost. PS. I'm in Australia, so could you mention your currency, so I can convert.
