Posters in several thread discussions of using legacy lenses on K-1 have mentioned the propensity of many nice older lenses to produce (Lo)CA and PF. Responders who actually
own the camera
and have tested legacy lenses on it
note that it isn't as bad as most people
believe it will be. People with a higher degree of technical knowledge then I suggest this might be a result of the larger sensor returning the full image circle, thus reducing the relative
area of (any) fringing, as well as the diminished density of the photosites.
All I know is, I have to work to coax PF out of the FA43, which has been called a 'PF monster' in the past (shooting birds with a K400/5.6 against a bright blue sky
is a classic example of 'wicked' PF), but LR and PSE correct fringing easily and quickly..
