the lens is sigma 85 f1.4, the highest regarding lens from dxo. dxo suggest it has the lowest CA they ever test with their combo.
the CA is shown on highly reflective objects like jewelry in a dimly lite indoor scene and around her beautiful curly black hair. that's after several hundreds shots in that session i realize it is a pain shooting with that lens.
In really dim light liked, iso 3200, f1.4, & 1/15 sec, ca is no there, it wasn't contrasty by then to ... shot handheld.
i prefer shooting than PS. That's just me.
nevertheless, thx for the wonderful suggestions.
