I seem to recall that field curvature plays a part in 'pop' also. Images from flatfield lenses don't seem to pop. One of these days I may torture and vivisect an M50/2 to change the element spacing slightly, to increase said field curvature, to see if it 'pops'. Igor, pass the spanner...

That's what I thought, too. Micro-contrast seems to be affected at the sensor level by 1) the Bayer filter (or lack thereof) and 2) sensor size as a factor of the diffraction limit. Since these sensors use the same Bayer filter (don't they?) then diffraction may be the culprit.
