Color shifts along sides of image with C Biogon
I have a 35mm C Biogon that I bought used - really happy with it overall.
However, when I got the M9 I looked into what lens coding to use, but it seemed from reading online that one wasn't really needed.
However, I get some color shifts with this lens that I don't know if it is a sign of something wrong with the lens, or if it needs to be coded, or even accepted and adjusted in post.
Anyway, the shifts I have aren't really in the corners like a vignette would be, but rather along the full sides of the shot. It looks very consistent as well.
If I shoot in landscape, the left side of the frame shifts towards magenta from top to bottom, while the right shifts from green.
If I shoot in portrait then for some strange reason the color shifts are reversed (green on left, magenta on right).
The color shifts looks like magenta and green from CA, I mean it's the same kind of tone/tint. This kind of leads me to believe that the lens is in fact not perfectly aligned?
Any ideas regarding this?
