gimp-lensfun 0.2.4-1
liblensfun-bin 0.3.2-4 ii
liblensfun-data-v1 0.3.2-4 ii
liblensfun1:amd64 0.3.2-4 ii
python3-lensfun 0.3.2-4
So everything is 0.3.2-4, except for gimp which is 0.2
I use lensfun with darktable 1:2.4.3-0pmjdebruijn1~bionic
I try to get a Sigma 70-300mm F4-5.6 DG OS working with _fullformat_ and
darktable 2.4.3. The lens works with APS-C, but not with fullframe
after the repo-installation. The correction suggested by me with a
comment in the xml-file was used with APS-C (and worked).
The correction below generally works for APS-C and FF, but it is not
recognized in .local-folder. It is a different correction that I
suggested. The correction below is for FF.
So there are 3 place where a correction can be:
/usr/share/lensfun/version_1/
/var/lib/lensfun-updates/version_1/
~/.local/share/lensfun
What I tried with different headers and maybe there is something wrong.
I removed _all_ correction for Sigma 70-300mm in
/usr/share/lensfun/version_1/ and
/var/lib/lensfun-updates/version_1/
So the only correction then was in ~/.local/share/lensfun. Darktable did
not recognize the lens.
I added the correction below in /var/lib/lensfun-updates/version_1/,
but have kept all existing 70-300 corrections. Darktable did not
recognize the lens with FF.
Then I removed _all_ 70-300 corrections and added the correction below
in /usr/share/lensfun/version_1/. Darktable recognized the lens with
APS-C and FF.
So this will work until the next update only.
I have backuped the original slr-sigma.xml, so I can restore them easily
for tests.
