To my surprise and dismay I noticed colour fringing in the center of the image. Below the full picture and a 200 % crop. You can see yellow/red fringing on one side and blue/purple on the other along the vertical structures. This isn't expected in the center of the image. The lens hasn't been knocked so decentering shouldn't be there. This picture is taken with the GH2 and 14-45mm set to 45mm and f/5.6. Anyone else ever noticed something like it? I'm a bit shocked about this behaviour, up until now I thought highly of this lens.
