Thanks Robert,

> I just submitted the Sigma 24mm f1.4 on canon mount, but not the 1.8.

the problem with the 24mm 1.8 macro and a lot of other Sigma lenses, is
the missing model name, so darktable / lensfun can identify the lens. I
am still thinking of this problem before I take shots for corrections.
So I know now, that there are no corrections for these lenses and it
makes sense to take shots.

Maybe someone can give a hint, how the metadata have to be changed, so
dt can recognize the lens? I asked this a few times ago, but never got
an answer.

It didn't help to change the metadata from nothing or Sigma only to

Hmmh, I undestand that you would like to include the corrections
directly, but isn't it easier that the admins copy it into the file for
the next time?

I don't know if this depends on the distribution, but it looks like the
lensfun-xml files are never changed, but a 2nd folder with updates is
created, where at least the Ubuntu-distri has problems with the
priority. In the meantime I use xml-files in ~/.local/share/lensfun and
_not_ updates. This is the only way it works for me after a lot of
testing.
