I did an outdoor test today and this is my test scene:



This is a resized version of the center sharpness test.

Considering the focal length advantage for the Nokton the Pentax-M 50mm is still managing to deliver better sharpness.
Again the Nokton has a lot of PF between f/1.4 and f/2, while the Pentax-M 50mm has some at f/1.7 but the PF is completely gone by f/2.

These kind of test was the way to manufacturer concern about sharpness only , nothing else , because people doing test like this.
