I don't mean to come across as angry. I do see often in forums with people of high degree and regard in the science of optics or theories or mathmetics, ...sometimes negating statements, just because it doesn't make sense on their fact list, etc.
I have used a 1Ds Mk1, and 1DsMk2, and the Kodak SLRc with Leica glass that is sharper than all the Canon L macro lens'. I tested them on a studio stand with the fixed lens on the mount, swapping the bodies..... and the difference is clearly in the image. I don't think I have those exact test samples as it was done for me to know what to work with. I would be willing to do a sample for you.
On that note...Although my Kodak file had a sense of MF quality/razor sharpness, the sensor does not handle differnt light setups well. I would think this is something that has been addressed at some point in the 6 or 7 or so years on sensor dev. So I use a mfdb. I recently used it knowing the lighting would work, and I do have a image from it, but nothing to compare it with.
I don't really know well this relation you explain between sensor and resolving power of the lens = needing a AA filter, but....
Maybe it is time for either Canon or Nikon to buy out the Foveon technology?
