I currently have an E-PL1 camera with the 14-42 kit lens for my vacation camera. Most of the time the camera is fine, but I've always felt that the combination of slow focusing (and sometimes inaccurate) and annoying to use button controls kept me from using it more often. I can pick up a E-PL2 or GF3 (or a NEX-3) for around $250 used. Is it worth upgrading? My main camera is a Canon 7D with a whole bunch of glass, so this is being used to compliment it Anyone go from the PL1 to a PL2 or GF2?
