	Marco is correct. IF you take a picture with a 50mm lens, take it off and
put on at 35mm lens from the same spot and take another picture then
compare them by masking off the parts of the 35mm print that is not in the
50mm print you will see that the two match. It is magnification that
matters. BUT, if the lens is not so good, you may find some distortion
effects that are unique to the lens. This will probably not happen with a
Leica lens.

	test prints are easy to do.

Incorrect. Perspective is dependent on lens to subject distance, NOT
on focal length.

At 19" the nose will bear the same relationship to he rest of the face
with any focal length. The MAGNIFICATION varies with focal length.
