Understood, regarding that it doesn’t change the file metadata. But I guess the thing that I’m driving at is that something changed between 5.7 and 5.8 such that Rawtherapee is no longer able to detect any of the lenses that it previously could.
However, it doesn’t appear to be an issue with the Lensfun as shipped because the profiles are there and there is no issue with manually selecting them and applying them.
I understand it’s not the end of the world and I can work around it by manually selecting the appropriate profile but it used to work and it’s the kind of thing that probably should work out of the box.
Judging by the number of lens identification posts that popped up post 5.8; I’m pretty sure I’m not the only one with this issue.
