AFAIK the 0.25 version doesn't support local configuration files, this needs 0.26. I have compiled 0.26 myself, but dt uses the 0.25 version. Finally I do not see a solution, even if local exiv2-files are supported. You need to change the metadata of the photo in a way that dt recognizes it. A local file could be a solution if exiv2 reports a hex value as I have seen with another lens. After doing some metadata changes with exiftool, I have this now with exiv2 0.26 001a00 (64 bit build), but note dt uses the older 0.25 on the same system.
