Of course I have. But sometimes one might just need to ask the question,
because it's there.

Yes, obvious enough from the pics.

I have a Fujica, but none of their lenses. I can't see anything in the
body/mount that could connect with anything on
the lens mount. The mirror box contains a mirror, shutter behind it and the
mechanism to push the aperture pin - that's all.

Yes, that's all clear, once I see the extra pin. Too bad they didn't make it
retractile, like the extra contacts on T
flashes. Looks like it would prevent using FTL lenses on at least some other
brand bodies. But maybe that was part of
the plan?

Looks from the pic like that's what Frank did.
