[OM] Medium and large format resolution

Something that I have been curious about for sometime is the resolution of
larger format lenses. A number of list users have admitted to the use of
non-Oly cameras, but only because Oly does not make equipment in the larger
formats. I understand. ;-)

I have never seen lens resolution tests for medium or large format lenses.
Are they published? If so what kind of resolution would one expect from a
pretty good lens. I would suspect that it would be substantially lower than
a lens for an OM or one of its competitors, if for no other reason than the
greater distance of lens from the film plane. Admittedly, it is less
significant with a larger piece of film that does not have to be enlarged
as much.

I suppose that if a Zeiss lens on a Hasselblad could resolve half the
number of lines per mm at the film plane as an Zuiko lens on an OM, you
would see a net improvement in the resolution in the final photograph,
aside from improvements in texture, gradation and finer grain.

Is there something in the relative size of the lenses and the amount of
film they are trying to cover that makes larger lenses, smaller lenses more
difficult to build with great precision, or is that even a factor in
today's technology.

I did see a fairly large collection of industrial photos in black and white
enlarged to 8 1/2 inches by 10 inches made with a Hasselblad and a Leica. I
could not tell which camera took which photo.

Any enlightenment?
