Some of the debate was acrimonious, and some confused. Yet with care taken not to oversimplify matters, I believe we can understand the relative performance of such different instruments, and learn why not everyone perceives it the same way, perhaps even without using too much mathematics in the process. Comparisons commonly use calculated data about image sharpness. It is relatively easy to make such calculations.
