But there are two weird behaviors unlike any other brand ...
The menu in ACR lists only one (1) NIKKOR Z lens, the one that matches the EXIF. Along with a long of other irrelevant lenses eg AF-S lenses, Nikon 1 lenses, etc.
This makes no sense—you can use a profile from an entirely different camera system and these are all listed (why?), but the only lens listed for Nikon mirrorless is the single matching lens for the Nikon mirrorless system.
Whether or not vignetting can be corrected during raw conversion on the computer in ACR depends on the camera setting at time of capture.
Vignette Control = OFF <=== ACR disables vignetting correction
Vignette Control = Normal <=== ACR enables vignetting correction
