Also, a question; as DOF deepens the more you stop down a lens, would a 1.0
lens, perhaps because of all that much more glass available, have a
proportionately better DOF at say 1.2, 1.4, 1.7, 2.0, etc, etc??

AFAIK all 50mm lens at ie f4 will have the same dof (as all 100mm or 135mm or
whatever, at the same f stop, the same dof) I think it's sort of a phisic rule.
Of course, bokeh, sharpness and contrast are other issues....
