A example of a potentially "lens limited" comparison

You are wrong here, as Erik has explained, whenever you use a camera with higher resolution, lens resolution figures will improves.

As a concrete example, you might think that due to diffraction a macro lens at f/22 would be "lens limited" on an APS-C sensor.  But look at the PZ review numbers for the Nikon AF-S 60mm macro on the 10 MP D200 vs. the 16MP D7000 at f/22:  1285 vs. 1761 lph.    Both numbers are still only "fair" relative to the best resolution seen on that sensor.  While you have to be careful comparing numbers due to the different processing and sample variation, that amount of difference is far more than can be explained by anything other than sensor resolution.

Just as a rising tide lifts all boats, rising resolution lifts all lenses.
