That's true of regular CA, but the Zuiko 180/2.8 has pretty severe lateral CA
- the stuff that shows up as PF (purple fringing) around highlight areas.
Unlike regular CA, it can not be removed with the standard CA tool in many
photo editing programs. There are some actions in post processing that can be
applied to remove PF, but they leave behind some nasties as well.
