I'm afraid we had to break this again :(
slr-tamron.xml: <model>Tamron 17-50mm f/2.8 XR Di II LD</model>
Exif.PentaxDng.LensType Byte 4 Tamron AF
17-50mm F2.8 XR Di-II LD (Model A16)
So the problem seems to be the Model A16 suffix :(
So looking into the Exiv2 sources:
{ 0x04e6, "Tamron SP AF 17-50mm F2.8 XR Di II" },
{ 0x07e6, "Tamron AF 17-50mm F2.8 XR Di-II LD (Model A16)" },
So to be honest I'm not sure how to proceed with this.... I'm tempted
to think this should be resolved on lensfun's end with aliases instead
of fuzzy matching....
The temporary workaround would be to create a local """alias""" by
copying the lensfun entry with a different name.
If you place the slr-custom-tamrom.xml into:
~/.local/share/lensfun/slr-custom-tamron.xml
Lens correction should work again.
