Darktable doesn't find my lens, eventhough it's in the database

It also doesn’t show my lens in the dropdown when I try to manually select it

The crop factor doesn’t match, this is an APS-C lens on a full frame body.

Thank you. I didn’t know that affected it. Is there any way to adjust it? Or can I just not do lens correction or auto lens correction with that lens?

Are you getting good results with this lens on this camera? I’d think there would be some very heavy vignetting.

You can, of course, make your own lens fun profile for it.

I get bad vignetting between 18-24mm but 24-55mm is normal

Does your camera automatically go into crop.mode?

I don’t know if it will affect the geometry corrections, but you could try selecting a crop sensor body.
