Can anyone explain what is happening here?

Hello! I'm having a weird issue with a Voigtlander Nokton 23mm f/1.2 lens. When I attach it to my X-Pro 2, serious vignetting, like almost unusable in most cases. When I attach it to my X-H1, almost zero vignetting. Same settings on both cameras. I'm at a loss as to what could be happening. Could it just have something to do with the Xtrans 2 vs. Xtrans 3 sensors? I'd prefer to use it on my X-Pro 2. Anyways, thanks in advance for your help!

If you look on the web page for this lens:

https://www.voigtlaender.de/lenses/x-mount/23-mm-11-2-nokton/?lang=en

the information (in the data communications section) implies the lens has limited compatibility with the X-Pro 2 but works fine with the X-H1.

It sounds like the X-Pro 2 does not have a built-in lens profile for your lens. That profile tells the camera or the raw developing software how to correct various distortions, such as vignetting, barrel or pincushion errors in the image, etc. Just about every lens has these problems, the lens profile is used to change those problems back into good images.

If you shoot using raw images, you may be able to find a lens profile for your raw development software and get better results.

hth,

p.s. Welcome to the forum.

Thank you so much! I was having a hard time figuring out what was going on. I really appreciate it!

remember that Adobe's DNG converter often has updated lens profiles that can permanently fix that vignetting in your raw files!
