  • I don’t know if darktable uses a version-1 or version-2 lensfun DB. I think it should use vesrsion-2 (that depends on the lensfun package version of course).

  • It seems that the DB you look at is not the DB darktable looks at. lensfun-update-data should provide the location of updated DB. That could be a third location. It should be much better to be able to provide the path to the DB to be updated.

  • you have to check the DB version identified in timestamp.txt. the last timestamp I get is 1583526137. It’s a flavor of julian date.

  • Your lens 35mm f/1.4 AS UMC is in this DB as well as the other lenses in your list. There are 13 Samyang lenses identified.

  • in the github lensfun repository branch master, the DB is not up to date.
