Great posts, Wim, thanks much. So nice to have the super simplified diffraction limit formulas of 1600 over aperture for lens aerial resolution with 9% MTF...and the roughly "3.2 times pixel pitch in micrometers" formula for smallest aperture that can still deliver resolution approaching what the sensor can resolve. What's the 50% aerial MTF version of the 1600/aperture formula? Obviously the number 1600 would be smaller.
