I see that you already stubled on the name problem and opened a ticket on lensfun.
It is not very conclusive, apart that names should be the same as in exiv2.
I think the answer will be the same with lens maker name(Ricoh versus Pentax).
So it seems the best is that let you continue to manage this issue.
How is it possible to verify the exiv2 names?
