The Olympus and Panasonic companies give up on correcting the distortion optically in most of Micro 4/3 lenses, delegating that task to a camera’s software. The PanaLeica 1.7/15 is not an exception to that rule. The distortion level on JPEG files is slight, amounting to just –0.91%. The real situation is revealed on RAW files and it is very bad indeed because a result of –6.04% cannot be called otherwise; it is also similar to the result of the Panasonic 2.4/14.

Still it is worth remembering that those companies are honest: they provide the size of the field of view cropped after the distortion correction. You don’t lose anything but still you can notice the effect of ‘pixel pumping’ and it certainly influences the image quality on the edge of the frame.
