Camer lens combo not found

[Fenny]

I treated myself on a Nikon z6iii +Nikkor Z 24-120 (aka, the kit)

Lens correction on the latest appImage (5.2.1) on Debian can’t find the camera/lens combo. The lens seems to be in lensfun. What could I do?

Hi, I would suspect that when you expand the lens correction module that the camera model is missing? It sounds like this issue

Nikon Z50 II and Lens correction support

Bingo! I’m running Darktable 5.2 on Linux Mint 22.1. I’ve installed liblensfun-bin, and after lensfun-update-data I finally see the lens correction working. It was not clear to me that I had to manually update the lensfun db.

You might need to update the lensfun database

yes, it seems that the Nikon z6iii is missing. On github, the z6iii is in the lensfun master branch (mil-nikon.xml)

I am compiling DT my self from the lates source in D ‘master’, which installs lensfun 0.3.4. That one does not include the z6iii

So the question now is:
how to I include the ‘master’ branch from lensfun in the compilation of ‘master’ DT

or: how do I update the lensfun database for an existing binary.

I’m using Debian as platform

You should have lensfun-update-data installed. But that may not grab the master branch.
On the other hand, on my installation (which uses the published versions and lensfun-update-data), I do have

    <camera>
        <maker>Nikon Corporation</maker>
        <maker lang="en">Nikon</maker>
        <model>Nikon Z6_3</model>
        <model lang="en">Z6III</model>
        <mount>Nikon Z</mount>
        <cropfactor>1</cropfactor>
    </camera>

in mil_nikon.xml

Note that you can run the lensfun update script either as user or as admin.

It will get the very latest database.
