these aren't entirely relevant due to the fact that these were shot on film. digital sensors respond differently to film in regards to lens resolution. the only truth that can be gleaned from this is the inherently low contrast in the Pentax 50mm f/1.2 lenses (both K & A series versions), and with decent PP skills that design flaw can be completely eradicated.
