I have both a Franka beam splitter and a Pentax one.  Your comments
aren't about beamsplitters in general, but are about the Franka one
specifically.  Franka also has rear-surface mirrors rather than
front-surfaced ones.

The Pentax stereo adapter (beamsplitter) doesn't have the problems you
had.

P.S. - One requirement for splitter also not talked about in the last
       month or so is that one should *ONLY* use them on front of a
       lens that does NOT rotate the front filter ring when it focuses
       (as the Pentax lens I attach mine to doesn't).  The Pentax
       unit is VERY VERY easy to use, align, and focus.  Auto exposure
       also works fine (with my Pentax SF-1 and other Pentax cameras
       that I've used it with).  Autofocus doesn't work, but it's TTL
       focussing, and so focussing takes only a second or two.

P.P.S. - The Pentax adapter isn't a cheap starting point.  Last I looked
         a couple years ago, Pentax charged something like $350 for one.
         Mine was under a hundred new, but that was a LONG time ago.  :-)
