It is easy to poo-poo the coating, but the body changes are significant if your style includes manual focus with the hood on. I own the FA 35/2 with no intent to get the HD, but I am quite accustomed to the focus ring after a decade or so of use.
Originally posted by someasiancameraguy My shooting style is more often than not wide open or one step down, and I find CA and LoCA distracting.
Prepare to be distracted, unless you spring for an apo lens. You want fast, you get CA. The true vintage lenses on your list will lack contrast wide open. The FA and HD FA are the most sophisticated of the bunch.
FWIW...I almost never use any of my 35's (I have several) wide open on 35mm FF and have never been vexed by performance of my FA 35/2 wide open on APS-C.
