Information taken from Exif to extract Lens info are processed by Exiv2 library. Yes, we use Exif to identify Lens... Look code here : http://lxr.kde.org/source/extragear/graphics/digikam/libs/dmetadata/dmetadata.cpp#941 But perhaŝ your model is not detected properly. Which Exiv2 version you use ? Gilles Caulier
exiv2: Installed: 0.18.2-1 Candidate: 0.18.2-1 Version table: *** 0.18.2-1 0 500 http://mirrors.us.kernel.org karmic/main Packages Canon uses different names to the same product, my camera has 3: Canon EOS 450D / Digital Rebel XSi / Kiss X2 Digital
According to Exif information (well detected by the way) my camera is a Model : Canon EOS DIGITAL REBEL XSi Manufacturer : Canon The lens auto correction has the equivalent model listed CANON EOS 450D DIGITAL which is the same camera The same problems but fixed is the previous model CANON EOS 400D DIGITAL CANON EOS DIGITAL REBEL XT
Can you give us an image sample to test ? Gilles Caulier

Digikam gets Exif.CanonCs.Lens Short 3 50.0 mm Exif.Canon.0x0095 Ascii 64 EF50mm f/1.4 USM and omit Exif.CanonCs.LensType Short 1 Canon EF 50mm f/1.4 USM Which is more similar to editor plugin's lens list. I didn't rich the plugins source yet so I don't know if it use another field to match the list This USM lens does not match exactly any in the list, I'll look for another example using camera kit Later Manuel
