I think that Focal has some issues with CA.
These are screen shots from the PDF produced in a fully automated (MSC) run with an 85/1.4G and D800. The top shot is the one chosen by Focal as th ebest quality (1880), the bottom is the one I might choose from those images saved (1504).
Notice the top has a lot of CA fringe, the bottom less so. That lens seems to show CA badly when out of focus in the negative direction (as this measures it).
I looked back through numerous runs, and while this is one of the worst, that seems to be true in a lot of places, as though it is mistaking a CA fring for a sharp edge.
Do your eyes see it the same way?
Have you had this? (or is my lens just bad and the real problem is I have too much CA?).
