I used my camera the other day with an OM lens with adapter. Today I wanted to take some pictures at a birthday party with the Panny 20mm. But with either the 20mm or the 14-42 mounted it seems that the sensor turns off. The LCD shows the icons but no image otherwise. It works find with manual focus lenses. Also with a native lens mounted, the shutter, autofocus etc. doesn't work. I can still get to the menus but that's about it. I've tried removed the battery, and the in camera reset. Anybody have any suggestions for rescuing this thing? Other than an upgrade to E-P3 I mean.
