P3D Re: 35mm Stereo format?

[Paul Talbot <ptww@xxxxxxxxx>]

John, do you mean the "infinity homologue spacing" of the mounts
is what you would like to be the same?  The RBT 5P mounts use
"European" infinity spacing.  I know RBT doesn't write the standard,
but would using RBTs for 5P and 7P give equal infinity homologue
spacing (assuming the chips are mounted to infinity)?  Or I am
way out in left field (as usual)?
