Nobody knows and Adobe does not tell.
You can check with the lens profile downloader if somebody maybe created a profile and shares it.
Thank you for your answer.
Meanwhile I have found in IRIX's web page that they created an LCP file for download.
How/where do I add this file to in the Lightroom / Photoshop so it will work ?
Funny enough, I'm Swiss and these IRIX lenses are Swiss and I never before heard of them
Thanks for all your help. It was great and now I'm good to go.
This is relatively a new lens and looks very promising
