I just pointed out exactly how micro-contrast can be technically measured. How is that sales talk?
"Sharpness" is not an accurate way to speak of this measure. Or else how can one distinguish the 30 l/mm curve from the 5 l/mm? They do not measure the same thing.

Micro-contrast is not subjective but instead a measurable technical quality. Many would consider the 30 line pairs per millimeter (lp/mm) curve on an MTF graph to be a good measure of a lens's micro-contrast performance.
"Pop" and "3D" are far more subjective, but have to do with how the lens renders the transition from in-focus to OOF regions. I am sure someone has come up with a way of interpreting MTF curves that might shed some light on this quality.

You expect to compare two completely different shots for microcontrast, when one is clearly OOF. That is an impossibility. And yet you say that I am being nonsensical for pointing out the obvious! :confused:
Just wondering: Is your belligerent attitude improving your photography?

I don't get it. The second picture is absolutely fine and technically better than the soft OOF first image.
