I recently read that 35mm shooters use a rule-of-thumb where they
determine the ratio from closest object to lens separation by dividing
by the focal length of the lens. For instance in a "normal" case 1/50,
which kind of makes sense to me as 1/30 in my experience seems to be a
little aggressive. Is there such a rule-of-thumb calculation for MF
(6cmX6cm) focal lengths? Please don't refer me to a chart, I want
simple.
Thank you,
Steve

That is a bad question to ask here. I would suggest that you find a book "The world of 3-D by Jac. G. Ferwerda" and read it. Ferwerda knows how stereo photography works and his book is the best on the subject that I know.

What is the meaning of, "past the end of the comfortable range of focus"?

IMO, if I am taking a picture of the moon, the parallax should be close
to ZERO.
