[Digikam-users] Lensfun -- most cameras and lenses missing

[Philip Johnsson]

Sorry, disregard my latest post. Missed that this was about lensfun and
lens correction and not exiv2 and meta data. With meta data and lens ID the
above comment is true.

With lensfun and lens correction there is an other database. Noticed that
my Tamron 17-50/2.8 isn't in the lensfun database so I will contribute the
correction data using Hugin to lensfun when I get time this weekend.
