I, likewise, have wondered about the visual differences between a process lens and a macro lens and have kinda thought that any difference may not be sufficient to cause worry. I have assumed that a process lens was designed and optimized for the copy of flat objects, thus optimized for flatness of field at a maximally large aperture so as to achieve highest resolution by minimizing diffraction. But darned if I can think of why one might yield images manifestly different from the other at a given FL and working aperture.
