Leica M240 3rd party lens codes

[BenXiaoHai]

I have a 35mm voigtlander 1.4 classic SC and 50mm 1.5 nokton screw mount lens. I was wondering which code you guys use on the camera to correct for the vignetting?

Can't seem to find the answer on google!

When I was using those lenses, I coded 35mm as Lux pre-ASPH and 50mm as Lux pre-asph.

Thank you.
