I've given up on lens detection. Manufacturers use the same lensID for more than one lens. This is discussed here: http://dev.exiv2.org/issues/1212

On the trunk, you can add your lens to the file ~/.exiv2 You need to know your lensID

Put it into ~/.exiv2 (or c:\Users\username\exiv2.ini on MSVC/MinGW builds).
