Typical lens testing protocol includes measurements of focal length, blur spot size, distortion, chromatic aberrations, field curvature, stray light, aerial image resolution, MTF across film/sensor size. Why they concentrate on MTF only (and publishing limited data on MTF, centre only) that I can't understand. Oh, no, I can.

Because none of those things is affected by a higher resolution sensor. Those are traits of the lens. However, the resolution is a trait of the lens and the sensor, so that is what was evaluated.

I do agree it doesn't make sense to pick a system based on absolute resolution alone.
