No, there are no in-camera lens elements. The lens mounts to the shutter,
and the leaf shutter sits in front of the mirror. As I recall, the shutter
shuts, the mirror flips up, then the shutter snaps. You then have to wind on
to flip the mirror back down and open the shutter again. Focus is soley by
microprism. I'm not sure why, other than I guess it was deemed more
appropriate than ground glass for a 35mm system. I imagine ground glass
screens of the day would be pretty dim, coupled with the slower lenses.

There were some cameras with leaf shutters that had interchangeable front
element groups rather than an entire lens change. The Canon EX was one and
the Diax cameras I to IIb. That way you got the advantage of a leaf shutter
and an interchangeable lens. Was the Bessamatic of this type?
