X-Ray lenses: a filter to complement them?

[Pancolart]

I wonder what kind of filter would make these strong purple coated lenses of extreme speed more useful for normal photography?

With cameras capable of close to zero flange like Nikon J1 and possibly Panasonic GH3 (electronic shutter) i think time to give X-ray lenses new life has finally arrived.

I have a few of those "monster lumen lenses" and use a very difficult filter for that ... none.



Works not too bad:
