I'm not sure that the A2 outresolves the lens. I think it just outresolves
technique. Back on my website, I had published lens tests on the A1. I was
trying to figure out the sharpest apertures. What amazed me was that with
the exception of wide-open and F11, there was almost no difference between
any aperture at any focal length. Granted, once you got past F7.1 things
started to slide downhill, but not by much. I found that the greatest
resolution trick in the book for the KM cameras was processing the images in
RawShooter. (RIP)
Also, I challenge the numbers on the 4/3 format. When talking resolution
limits with digital, the diagonal measurement no longer applies. The sensor
height of the 4/3 sensor is almost that of APS-C. Feel free to use the same
calculation for APS-C.
With almost all of my lenses, I can go out to F8 without hitting defraction
limits.
