Axial CA on 85mm f/1.2L II

[Shea Design]

Hhmmn,, saw this in the review:


All three copies of the Canon EF 85mm f/1.2 L II USM Lens I have used
to date show more CA (Chromatic Aberration) than the older 85 L.
And my 85 f/1.8 shows less CA than either version of the 85 L lens.
The 85 II lenses I have used are producing noticeable CA at the widest
apertures when sun glares from something reflective in the shot (such
as a chrome car bumper).
For most applications, the CA will not be a big deal - and removing it
in post-processing is often possible.


Seems it is the nature of the beast. Maybe ND filter a few stops.

All my fast lenses produce quite a bit of CA. I think the 35L is the worst but is only a problem with certain shots like you very high contrast edge shot there. I haven't played with the 50L enough to compare it's CA. I think my 85L would probably kick out similar CA. Maybe even worse, I'm not sure how or if a FF sensor affects CA differently.
