To pick a nit: diffraction effects not changing with focal length might be reasonable for a specified sensor/film size, but not otherwise. The old timers who used 8x10" (or larger) format cameras shot landscapes at f/64. If you tried that with an APS sized sensor the results would not be good - as shown at the site Mark linked to.
