This lens can I recommend it to anyone who calls a MFT camera his own. It offers a on 35mm equivalent focal length of 24mm (MFT to full form factor 2 count), a good wide-angle for urban, landscapes and portraits with ambience. The workmanship is excellent and the class optical imaging. This lens plays loose in the league with Canon L lenses (corresponding to the MFT sensor replicates). Very nice I also like the change to manual focus on the click back of the focus ring. This is beautifully smooth to move, not too light and not too heavy, just perfect. Are already at full aperture the photos knackscharf, almost distortion, no chromatic aberration and only slight vignetting. So nothing that can not be corrected by the post or in the camera's internal processing. It is priced although quite expensive, but absolutely worth the money. In addition to the Olympus 45mm f1.8 and the M.Zuiko 75mm f1.8 M.Zuiko one of the best prime lenses for the MFT system.
