Well, I zoomed to the 29 minute mark. I don't think his explanation really applies in the case of P.J.s photo because I don't think the fringing is in front of the plane of focus. It is just around the transition area of white (to darker). I'm sure that if Zeiss would send P.J. an Otus 85mm for use on his K-5II he would be happy to try to see if it makes the problem go away, however. Sadly, it is only currently preorderable (is that a word?) for Nikon/Canon.
It is still possible that it is an artifact of post-processing. A question for P.J. I'm assuming, P.J. that you see it in the RAW files also, before processing or compression? I've seen some derogatory comments on the web about purple fringing being an issue commonly known (as in, a given) regarding Sony sensors. No idea if that is mularkey or not - or was possibly true at some times and not others?
