The Micro 4/3 system optics constructors usually give up on distortion correction, leaving that task to cameras’ software; it is true even when you deal with lenses with moderate angles of view. For example the Panasonic 1.7/20 showed very significant “barrel” on RAW files, which level amounted to –3.66% and the Leica 1.4/25 was only slightly better, with the distortion of –2.30%.
The performance of the Olympus sticks out in a positive way here because the tested lens corrects the distortion very well, no matter whether you use JPEG or RAW files. In the first case the distortion level reaches −0.82%, in the second it is −1.12%; both these values can be called moderate and are significantly lower than those of lens’s competitors.
