Theoretically, no. Generally, one would expect the 645 system to be sharper
than a 35mm system owing to the larger negative. This is not just because of
the grain, but also because less resolution is requires of the lens. This is
a good thing because it's harder to make a lens cover the larger format and
usually both resolution and speed suffer. This all translates to no
advantage in quality and usually a slight lowering of resolution. Usually
the 645 lens will be slower. What's the advantage? well, if you already own
the 645 lens you save money, and if you're carrying both formats in the
field, you don't have to carry the 35mm lens of the same focal length.
