Sorry Steve, I dont believe this is correct.  Magnification should have 
nothing to do with it.  Its simple geometry.  Imagine a line right down 
the center of the focal area, now move that line in a parallel way some 
distance, i.e. 1mm.  The entire line, being parallel, by definition is 
1mm apart from infinity to infinity.

Assuming the line corresponds to a beam of light, you *can't* move it in 
a parallel way.  If it's straight on-axis (which the light will be, if 
the lens is symmetrical about its axis) it'll be bent off-axis.  That's 
what lenses do - they bend light.
