I think it's helpful to start such exercises by defining what you want the test to accomplish, Mike. For example, do you want to find out which of your lenses provides the highest optical resolution? Or, alternatively, do you want to simply explore the characteristics of each lens at different apertures?

The choice of the "best" lens depends on the objectives for a specific image, and the conditions under which the image is being shot - not necessarily the optical resolution of the lens.
