The Leica D 14-50mm exhibits a little fringing in the extreme corners at wide angle and some light fall-off at its full f2.8 aperture, but the results are still quite sharp, especially compared to the older Zuiko Digital 14-45mm kit lens at 14mm f3.5.

Zoom into telephoto and the Leica D 14-50mm performs very well in the corners even with the aperture wide open. It is noticeably sharper than the latest Zuiko Digital kit lens when fully opened, where it also has the advantage of being over one stop brighter. A great result here for the Leica lens.

Note: crop details taken from the same chart which appear smaller here are due to them being captured with lower resolution cameras and / or a lens which couldn't focus as close to the chart. In each case though, the crop still represents the extreme left corner of each camera's frame.
