If you are talking lppm on the film, that's generally true. If you are
talking lppm on a printed image, it ain't necessarily so. In simplest
terms, a 50mm lens with 50 lppm resolution on 35mm film will deliver the
same sharpness on any given size print as a 125mm lens with 20 lppm
resolution on 6x9cm film. (Only talking taking lenses here, not grain,
tonal range, enlarging lens, film base, yada, yada, yada) The MF image
on film is 2.5 times larger, so it needs 2.5x less magnification to
print size. When the question goes beyond the exact plane of focus, the
answers get even more interesting.

It is well known that 35mm lenses are sharper than medium format and
