The Micro 4/3 system approaches distortion correction in different ways, depending on a lens. Telephoto devices with a moderate focal length, easy to be corrected with optics, are rarely supported by software. In case of a standard model like the OM M.Zuiko Digital 20 mm f/1.4 PRO different tactics is applied.

On JPEG files distortion is practically non-existent, amounting to −0.11%. One glance at RAW files, however, shows you the real size of distortion – here you deal with distinct barrel variation of −1.60%. Taking into account the angle of view of 57 degrees, provided by the tested lens, it's nothing you have to worry about. We've seen similar or even worse results while testing classic standards with smaller, easier to correct fields of view, amounting to 47 degrees.
