metadata).

In 1.5.0, i included current implementation of LensFun in digiKam core (to be
able to compile and use it under Windows)

Please update

Ask you can see in my screenshot, lens cannot be found because there is no lens
info avaialble in your image metadata.

About focal lenght = 300 mm, it come from metadata. So, it's a problem with
your camera.

i knew about the focal i don't know how to force actual focal to be written in
the metadata (i have a clue with an option in the camera, i'm on it). For the
metadata i apologize, i saw that i put a reduced version online (now corrected
