While using Exif.CanonCs.Lens may appear to be a "nicer" format than the value 
65535, it actually has less information and might match other lenses that just 
happen to have the same zoom range. Therefore using Lens instead of LensType 
rather seems like a quick&dirty workaround to me.

If you would be so kind and follow the instructions here:
http://www.darktable.org/2015/02/on-lens-detection-and-correction/

This would not only be a quick workaround, but allow _all_ programs using 
libexiv2 to show the full info on that lens.
