Darktable reports the lens name "OLYMPUS 14-42mm Lens" for the lens
Exif.OlympusEq.LensType Byte 6 Olympus
Zuiko Digital ED 14-42mm F3.5-5.6
Exif.OlympusEq.LensSerialNumber Ascii 32 212686538
Exif.OlympusEq.LensModel Ascii 32 OLYMPUS
14-42mm Lens
Exif.OlympusEq.LensFirmwareVersion Long 1 4869
Exif.OlympusEq.LensProperties Short 1 49223
and, in the same way, the (way too unspecific) Exif.OlympusEq.LensModel
data for the other two FT lenses. I'm pretty sure, that somewhere some
part of the code should say "oh, this is a FT lens, I'll use the data
from Exif.OlympusEq.LensType.
Given the data, that I quoted for the "Olympus
M.Zuiko Digital ED 12-50mm F3.5-6.3 EZ" lens and that
Exif.Photo.LensModel is set for that, but not for the FT lenses I own,
this may also work with:
<pseudocode>
if maker == "Olympus":
if isset(Exif.Photo.LensModel):
return Exif.Photo.LensModel
else:
return Exif.OlympusEq.LensType
</pseudocode>
Yet, I don't know the darktable or lensfun code, so I don't know which
component has to do this.
Take care,
Jan Niklas
