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.

of the lens and I've never noticed any CA on a digital body even while
pixel peeping. I have seen a fare amount of sensor bloom in high
contrast images.

I added a few shots to the set. Had a chance to shoot in bright
sunlight
today.
The lens does exhibit some fringing, but less than many lenses pretty
much
toward the edge (image imgp7583 center and full image) and not much
in the
center (image imgp7581 center) though it is visible in a
high-contrast edge
(imgp7571 center).
What impresses me most is the image rendering (imgp 7571 & imgp7577 full
image). The tree is beautifully separated from the background.
Bokeh is clean, for lack of a better term.
Conclusion: While I do not really like the fringing it's not
offensive on
this lens. And after shooting LF the rendering principle is always
in the
forefront of my evaluations. This lens certainly passed today.
