My owners manual says that the Realist model 81
has 3.5 inch f 2.8 lenses.  It says that the model
82 has 3.5 inch f 2.3 lens.  The projector I
tested was a Realist model 81 and my TDC 116 has
the 4 inch lenses.  Yes, I adjusted the the
projection distance to compare equal size images
on the screen.  -   Don Parks
