Samyang 8mm fisheye: rear-mounted filter?

I need a strong ND filter, say 6-10 stops.
Unfortunately Kodak Wratten 96 series gelatine filters are getting very expensive ($60+) - is there an alternative? Thin glass filter 37mm?

Yes I know there is no filter holder behind this lens, but I will improvize for a day-long shooting.

If the lens does not protrude in back of the flange, you might be able to rig something. The mirror needs room, but there are examples of filters fitted across the flange. Astronomix makes such a clip-in filter, and the Sigma SD1 has a removable IR filter in that location. It might be simpler to rig something in a compact, as mirror fouling is not an issue.

Interesting site and idea
However these are *not* ND filters.. and rather expensive also.
