I don't think he made any assumption about the resolving power of the
zoom other than it was likely less than his 85mm Nikon prime. He simply
took two pictures... one with an old zoom on a 5D and the other with a
top notch Nikon 85mm prime on a D200. Then he shows a 1:1 pixel crop
and shows that the 5D image is superior. And, by the way, it is very
much superior... not just a bit.

I can't find anything in his article that would support your statement
above. The only statement he makes about prints is that a print made at
the same low resolution as the screen shots shown here would be 1.1
meter wide. He makes no comment whatsoever about the quality of such a
print nor does he imply that one should make such a print.

Regardless, I do see a big difference in his paired images. Are they fake?

How did the lens slip in here or don't I understand? I thought we're
talking about the diffraction limitations of the sensor itself. A good
lens doesn't help beyond a certain point and given aperture.
