6. Distortion

We didn’t expect bad results in this category because tele lenses of this class almost always correct the distortion in a perfect manner. In the case of the JPEG files we got −0.14% for the lens and −0.13% for the lens plus the 1.4x tele-converter combo; mind you these values say nothing about the performance because the Micro 4/3 system corrects the distortion of JPEG files anyway.

Still the transition to RAW files doesn’t change anything. With the bare lens attached to the camera the distortion amounts to −0.16% so, within the margin of error, is the same as in the JPEG files. After attaching the tele-converter the deformations increase to −0.66% but that level is still low and shouldn’t bother you at all.
