  I assume to have a single camera that uses a
single roll of film. Some people are worried about
process variations making the L&R rolls different
when separate rolls are used. Though I haven't
noticed any problems with my Ricohflex rolls.

  Three element lenses will do well in the center
of the image when stopped down. But I don't think
the edge sharpness will match that of a 4 or more
element lens unless you stop down so far that they
are both blurry from diffraction effects. So that
is what I think Don was surprised about.

  I did a dejanews search on LOMO and didn't find
anything about a TLR. So I'd like to hear what
you find out from this fellow about his cameras.
