I think the comments about vertical misalignments applies to a "beamplitter"
as well as to the Realist.  The difference with the "beamsplitter" is
that the attachment needs to be aligned with the camera it's attached to.
If there is a rotation there, it's a problem.  Rotating the camera+attachment
as a whole should be the same as rotating a Realist.  

Another reason why it's *really* recommended that stereo adapters be used on
lenses which don't rotate the front filter ring when focussed.
