As long as you work with JPEG files the distortion won’t be a problem – it is corrected by the camera’s software. Officially you deal here with its barrel variety amounting to −0.48%.
You see the real image of distortion only when you develop a RAW file with independent software such as dcraw. Then you find out that, in the case of the Panaleica 1.4/12, that aberration is huge, amounting to as much as −5.39%. It is clear the lens constructors gave up the distortion correction completely, letting the camera software deal with it.
