To fix the distortion. Any free or cheap software recommendation?
Any tool which uses liblensfun will work. If your lens isn't in the database you can add it using a set of calibration photos of something immobile (houses are nice) and hugin.
So in specific rawstudio, ufraw, darktable and gimp (using the gimp-lensfun plugin) will all get you correct lens distortions (and CA and vignetting) given the data.
That said, not all m4/3 lenses are in the lensfun database. So if you're like me you'll want to create your own lens profiles first.
