Steve,

because the body is thicker, the oculair (the lens that is at the back 
of the camera) is farther away from the optical parts in the finder. To 
create a sharp image, its optical properties have to be changed. This 
cause the different magnification of the finder.
If the magnification had to stay the same, the whole finder had to be 
redesigned.

regards
