[digiKam-users] Camera and lens ID failing for lens correction

[Maik Qualmann]

The problem is the assignment of the manufacturer. The PEN-F is in "Olympus
Imaging Corp." registered. In the image, however, "OLYMPUS CORPORATION" is
given. Olympus has 3 different manufacturer names in the Lensfun DB, we
would have to check all 3.
