Great news for C1 Pro users! Since 12.1, released yesterday, support for Z lenses nef built-in profiles was added!
I tried on images shot with the amazing 24-70mm f2.8 S and a bit less amazing 14-30mm f4, and it works perfectly!
This is great because this means that upcoming lenses will be immediately supported as long as Nikon continues to embed profiles in their raw files.
Cheers,
Bernard
