Actually, the infinity spacing is the same regardless of the 
aperture spacing of the mount.  There is a very slight difference 
between the standard infinity spacing for 5-perf and 7-perf which 
is unfortunate but tolerable.  So the variation in aperture spacing 
results in a variation in window depth.
