One teaser quote:"The... thing to realize is that resolution is not a quantifiable scientific absolute"
Sorry @FlowtographyBerlin, but your reasoning on absolute vs relative is incomplete -- and so everything else falls apart.- The first test (at Bonneville) is an absolute speed test.- The 2nd and 3rd tests are relative tests. Also, a higher number from one track is not "more valid" compared to a lower number from another track. And importantly, the numbers do not at all correlate to the absolute maximum speed my car can achieve.MTF50 testing as presented by lensrentals, Photozone, etc., are similarly relative tests. They are not measuring absolute max resolution. They are measuring the camera+lens MTF performance at the very specific, non-standardized test conditions with different charts, lighting, RAW conversion, etc.Just like the track tests, the lensrental and Photozone numbers are not comparable. The Photozone numbers aren't more valid because they're higher than the lensrental numbers. Neither set of numbers have anything to do with the absolute resolution of the camera. And lastly no, the lower lensrental numbers do not in any way imply that the sensor is "out-resolving" the lens.
Now, your assumption, 1000 pixel = 500 LP is in my eyes wrong. I always see the charts mostly being black and white. To reproduce them with a Bayer pattern, with a Foveon sensor or with a monochromatic sensor will drastically change that parameter. So even if you understood what a pixel is for you it might not be the same for me.
"Modulation" in the Zeiss paper I tried to understand appears not to be a rapid change of black and white, which would result a very steep curve like black on/off. It's a pattern going softly as gradient from black to white and looks like a sine curve.
I'm still listening, reading and doing the best I can to consume and understand all this...the bottle of red wine is starting to taste even better how that I got some cheese & crackers. If anyone care for some let me know I will get an extra glass. Maybe at the end we can use the MTF charts for dart practice. :POne thing for sure, I will not be driving the Porsche anywhere unless it has been fine tuned for any steering wheel pull.

Thank god the car analogies ended! ugh! I'm just sitting back watching people finely learn what MFT is.
Well, analogies help to make things more accessible. So why be annoyed?
