I've been reading the OM-D/5D2 thread with great interest. I prefer the E-P3 form factor over the OM-D, but that thread has me thinking maybe both is a good answer. I'm really hoping for an E-P5 with the same sensor, obviously. Now that some of us have been shooting with the OM-D for a while, can we have a discussion on the humming/vibrating issue that popped up initially? What's the deal in real life use? That would annoy the hell out of me, and likely just keep me waiting for the next PEN.
