I've taped the lens' contacts (so there is absolutely no correction) and here is the result with a foil paper. I don't see the amount of LoCa from your Sigma 35/1.2 test.
It's not free of CA but I think it's a great performance for a 35mm lens at f/1.2. (Better than the f/1.4 alternatives)
Your Leica 35/2 is APO and it's not f/1.2. The Sigma will probably get very close to its LoCA performance once stopped down to f/2.
Do you have the full pic so I can estimate the focus distance?
I think it is very important as the purple green fringing is dependent on subject distance, how OOF it is. I also dont see much of the foil in front of focus plane?
I took a shot and I see lots of purple LoCA and green LoCA on my copy so I think it is normal.
Lighting condition is nighttime with Flores ent down lights.
On my test shots outdoors I actually thought it’s loca is pretty ok...
