The optical performance of the Olympus M.ZUIKO 30mm F3.5 Macro is outstanding. 
The lens is included in the list of the 10 best lenses for Micro Four Thirds. 
The unsharpened RAW files already show at full aperture a very high sharpness, both in the center and in the corners. The shift toward the corners is very limited, as it should be with a macro. Stopping down to f/5.6 provides a small improvement in sharpness, even though that is sooner measurable than visible. Smaller apertures are still usable if that is really needed to achieve the greatest focal depth.
