Just looked at my modified xml 's in /home/xxxx/.local/share/lensfun
I see that my files have a first line in each file:
<!DOCTYPE lensdatabase SYSTEM "lensfun-database.dtd">
BUT does not have <lensdatabase version="2">
Not sure why or what this does !?

Thanks, I'll check. Unfortunately the problem is that I am trying to
select the lens _manually_, so it shouldn't matter the RAW EXIF... ¿or
not?

Probably a long shot, but ...
Check the entry in the EXIF data of your photo file has the same
case, and syntax, as the entry in your <lensdatabase> file.
Look for Lens type or Lens ID. (IIRC)
This caused me grief in the past where the entry was lower case in
the photo EXIF data but did not match in Lensfun.
HTH,

Hi,
I tried also without the variant line. Same thing, the camera
appears in the lens correction module, but the lens dropdown is
empty. I doble checked the spelling of the camera and compared the
entry with others, but I really can't see why this is not working.
Should I open a bug? Or is still an operator error?

The variants apparently don't work, see:

But they shouldn't be needed in this case anyway.
Otherwise, not sure why that wouldn't work.

For compact cameras, you also need to add the entry for the
camera itself along with the lens:
<camera>
<maker>Panasonic</maker>
<model>DMC-TZ100</model>
<mount>panasonicTZ100</mount>
<cropfactor>2.75</cropfactor>
</camera>
Also, you might have to remove that 'version="2"' parameter to
get darktable to load the file.
Ok, now I have the camera but not the lens (
http://pix.toile-libre.org/?img=1495308076.png ) --- The second
dropdown
is empty.
I tried to add a <variant> record to no avail.
Any further hint? Thanks!
