"Note that CAs can easily be corrected in software or by the camera itself (most modern Nikon DSLRs remove CAs themselves if you shoot JPGs). However, with values that high, CAs will have an influence on perceived sharpness, even if the colour cast at contrast edges can be easily removed."



There is a difference between masking CA's (like I suspect the Nikon cameras do?) and correcting. When you correct CA, sharpness and contrast improve and the coloured edges just disappear. Just removing coloured edges is masking, correcting involves scaling the offending R, G or B channel so that all colours have the same size image again.



So depending on your software and/or method, correcting CA will make the CA totally undone.
