My writing style is suffering from something, that's for sure.
First off the image quality seems to be pretty nice.
Now my comment:
All the Pentax manual focus f4.0 200mm lenses are supposed to be very
good. Though going against the usual pattern, the M version seems to be
sharper with fewer aberrations, than the K or A versions. The K is
supposed to be the next sharpest while the A has better flare resistance
probably due to it's slightly simpler optical formula and better coatings.
There, that made more sense, I think.
