I am relatively new to m43, having moved up from point and shoot last year. I have the G3 with the 14-45 lens I picked up used. The lens seems to be in perfect condition. When I take pictures of bright white or shiny objects against a dark background I get a strong purple fringe or halo around them. It's usually in low light conditions. I am aware of chromatic aberration, but that is usually at the edges of the photo and a very slight fringing. This is a thick halo around the objects and in the center of the frame. I'll post some pictures when I get a chance. Is this a common problem or is there something wrong with my camera or lens?
