Far be it from me to tamper with the laws of optics!   (Other laws, perhaps, 
but not the laws of optics!)

I'm just speaking empirically, from my own experience.  I use a Beseler 
negative carrier that has a 25x37mm opening to show the whole negative plus 
some, and negatives that I have shot with my 21mm Skopar almost fill the 
25x37mm area, while shots made with my 50mm Summicron leave a lot of clear 
negative showing.   When I had the 12mm VC lens, it filled even more of the 
carrier opening.

I have always been fascinated by the difference in size of Rollei and 
Hasselblad images.  Rollei makes a full 56x56mm image while Hasselblad only 
can come up with 54x54mm, which is a fairly significant difference, in my 
humble opinion.
