Zuiko 20mm f/1.4 PRO review by Lenstip

20mm f/1.4 at BHphoto. Adorama. GetOlympus.

Lenstip tested the lens and concluded:

I admit that, while writting this summary, my feelings were mixed. On the one hand the OM System M.Zuiko Digital 20 mm f/1.4 PRO is a shapely, well-put-together, weather-sealed lens that is able to provide excellent image quality in the frame center and moderate vignetting. Its autofocus performance is also beyond reproach. On the other hand the lens had many average results in different categories of our test and two painful slip-ups, quite unexpected in an instrument of such a type. I especially can’t understand why a standard lens with 11 elements inside, four of them made of low dispersion glass, deals just moderately well with both types of chromatic aberration.
