I have the same lens (according to the writings on the lens, exif/makernote
says different) and the dropdown menu is now filled correctly, but the lens
itself is not detected. Running Digikam 3.0.0 and lensfun from svn (doc path
indicates the version 0.2.7.0).

From exiftool:
$ exiftool P2070135.JPG|grep -i lens
Lens Type                       : Olympus M.Zuiko Digital 14-42mm F3.5-5.6 II
Lens Serial Number              : ABGA07554
Lens Model                      : OLYMPUS M.14-42mm F3.5-5.6 II
Lens Firmware Version           : 1.103
Lens Properties                 : 0xc140
Conversion Lens                 :
Lens ID                         : Olympus M.Zuiko Digital 14-42mm F3.5-5.6 II

And information from MakerNote tab inside photo editor:
Lens Firmware Version : 4355
Lens Model : OLYMPUS M.14-42mm F3.5-5.6 II
Lens Properties : 49472
Lens Serial Number : ABGA07554
Lens Type : 0 0 9 16 0 0

In the dropdown there is OLYMPUS M.14-42mm F3.5-5.6 II available, but it is not
selected automatically. Also the label for detected information is just empty,
while for Make and Model they are correctly selected.

Okay, I did some research today

Also, anyone knows why LensType is used instead of LensModel for detecting the
lens? It looks like recent change has added LensType parsing (which was also
mentioned in the sources, http://dev.exiv2.org/issues/879 is the change).

The problem is though that Lensfun expects a "cutted" version for which there's
a special case for Nikon lenses in LensFunIface. LensModel seems to be the
correct for Olympus though. I have submitted a patch to reviewboard to add
LensModel for checked tags, url: https://git.reviewboard.kde.org/r/109017/

Output from exiv2 -pt:
Exif.OlympusEq.LensType                      Byte        6  Olympus M.Zuiko
Digital 14-42mm F3.5-5.6 II
Exif.OlympusEq.LensSerialNumber              Ascii      32  ABGA07554
Exif.OlympusEq.LensModel                     Ascii      32  OLYMPUS M.14-42mm
F3.5-5.6 II

Unfortunately for me the detection algorithm will give two results, both for
"normal" and "R" version of the lens and doesn't thus autoselect anything.
