Sergio,
This sight seems to contain some of the info you are referring to. I
didn't go through all of it but, I think your answer may lie within. I
notice my medium format mounting guage has a near/far parallax of about
2.5mm. My views often go a bit wider than that. So if you have a pair of
Horizon cameras with 28mm lenses and a stereo base of 150mm (which is
minumum possible).....28 x 150 = 4200 / 3 = 1400mm or about 4.5 ft...
Seems about right to me.
