It is very soft at 4:1 and f/2, and has CAs. At 1:2 there are also CAs, and the field curvature gets strong.

There is no field curvature worth mentioning (tested it just now). I think you may confuse some coma like effect, or more probably astigmatism, with field curvature?

Your 60mm AF-S has quite strong CA, just your camera is hiding it. Try a 3rd party RAW convertor to see how it really performs. The still quite low CA from the 55mm f2 can also be easily reigned in in a RAW convertor that allows you to correct CA, or in photoshop (in for instance the lens correction filter).
