P3D Zero magnification?

You mean to say using lenses instead of mirrors?  The concept of
magnification is universal and applies for both systems.  The
focal length of a viewer is equivalent to "viewing distance". 
There is a viewing distance even when you use a mirror device. 
Since you are viewing prints which have already been magnified
(enlarged) you should take this into account.  I am trying to
think of a forula for the magnification factor of the View-Magic
system.  Can someone help?  Also, what is the viewing distance
of the View-Magic format?

PS. I think the term "refractive" is used for a system with
lenses and "reflective" for a system with mirrors.  Is this correct?
