JPEGs sent via e-mail. Sorry for delay, hunger interrupted editing. I'm
going to use more kitchen skills to combine water kettle tea and milk
(hopefully in the correct sequence).

That's pretty impressive axial CA cleanup.
I tried to match the sharpening:

top is from lightroom, bottom with Capture NX2,
left is f/8, right is f/2.8

So, I downloaded a trial version of Capture NX2 and it does work nicely
for this. There is still a cyan fringe but much better.

-that's just working off the jpeg, I never saved NEFs, out of spite for
Nikon's software <g>.

Note how the top LR examples alias/moire the purple into alternating
bands of red & blue where NX gives a smooth edge. NX does leave red in
the fringing, it only takes out the blues. It doesn't touch the yellow
green axial fringing in the background but that's less objectionable to
start with.

Nicely put. Now I've learnt NX2 it does what I want and with minimal effort,
but if they start building camera firmware to the same standard as their
external software I shall give up photography and learn to draw with
crayons.
