Zuiko 9-18 m4/3 lens: "Chromatic aberration Wideangle zooms are bound to suffer from a degree of lateral chromatic aberration, but the M ZD 9-18mm F4-5.6 shows more than its fair share, with strong red/cyan fringing towards the corners of the frame at all focal lengths. In fact the fringe widths are some of the highest we've seen, and in unfavorable circumstances can be readily visible even at relatively modest image sizes. Unfortunately Olympus does not pass correction data to the camera (alongside the obligatory distortion correction), so the color fringing shows up with both Olympus and Panasonic camera bodies. However it can of course be suppressed when processing raw files."
