Yes, that's the goal. I'm currently evaluating lensfun. Currently I
see the following issues using lensfun from inside Hugin:
1.) Lensfuns reports only a very general lens type fisheye. Hugin
supports circular fisheye, full frame fisheye, orthographic,
stereographic, equisolid, Thoby fisheye.
2.) The crop rectangle/circle is not stored in the database.
3.) Lensfun does not natively build on windows (you can only cross
compile on linux for windows).

That looks good for the Sigma. For the Tokina this is more complicate
(because exiv2 can't identify it correctly).
