In comparison with other Micro Four Thirds prime lenses (mounted on a Panasonic Lumix DMC-GH2), the Olympus M. Zuiko Digital ED 60mm f2.8 Macro scored quite well with a DxOMark score of 17—though, as expected, high-end lenses with shorter focal lengths and wider apertures were able to score slightly better.
Given that sharpness is a critical quality for macro shooting, the M.Zuiko Digital ED 60mm f2.8 Macro’s Sharpness score of 9P-Mpix was particularly welcome, making the Olympus lens one of the sharpest Micro Four Thirds prime lenses that we’ve tested.
The lens was able to achieve its maximum sharpness of 9P-Mpix at f/4, with just a slight softening toward the edges of the frame, but at an acceptable level, as shown in the field map below:
The 60mm macro lens exhibited very little vignetting, with a Vignetting Score of -0.7EV, giving it the best score among Micro Four Thirds prime lenses. You can see from the field map below, that at its maximum aperture of f/2.8, it exhibits minimal lens shading across the field.
