I received used but almost new E-PM1 yesterday, 22 months out of 24 months european warranty still left. I like the form factor and the familiar menu system but to my surprise there is a IS related problem. When I power up the camera it makes a shutter release and makes a weird buzzing sound. After start-up the IS logo just blinks at the upper right corner of the screen. I believe that it indicates the IS is not working properly. I have contacted Olympus service but I haven't received any answer yet. I can still shoot normally but I quess I have to send this little beauty to the warranty service soon. I made a boring YouTube video to demonstrate the problem. This is just for those who might have same kind of issues with their Olympus camera. I will report back how this ends up.
