Outresolving the sensor

As a simple thought experiment you might test a lens on 12MP sensor and because the sensor simply can't resolve the very finest detail the MTF results would show the center, edges and corners perform nearly the same.

Sorry - you seem to repeat a fairly common internet myth.

No lens out resolves any sensor, and no sensor out resolves any lens.

If a lens lays down significant detail at sufficiently high spatial frequency that the sensor cannot correctly interpret those frequencies, the lens is outresolving the sensor.
