Some of my lens are recognized with an ID rather than name, obviously because exiv2 is still used (They have to update their DB?).
"lensfun-update-data" didn't have an effect.
Is it possible to include this lens info or will the recognition be changed/extended in a future version to be more reliable?
Except the 50-100mm the lenses are not that new.
