Yes and no (in that good contrast gives the appearance of resolution being better and poor contrast will mask good resolution) . Also, we can work on contrast in the darkroom thankfully. AA commented that some of his older lenses had poor contrast, not that you would know looking at some of his later prints which exhibit very high contrast.

On the subject of the Mamiya 7, the lenses are so sharp that they are up to the challenge of 35mm primes (I beleive the 50mm hit over 115 lpmm at about f5.6 in a test by Perez).
The other issue here is to get 35mm to look like MF, you have to use films like Acros and be very careful all along the way. Personally, I dont particularly like the look of these modern T grain type films and it seems awfully restrictive to only have a few narrow options to get the creamy results. If I want fine grain and tonality, I would rather grab the 'Cord and any film I choose, with the flexibility of any developer I choose with room for errors. A related point is that the worst 5x4 lens I had was was indistinguishable from the best on anything less than a 16x12 and even then you had to touch the print with your nose! The real estate did all the talking at this size.
