I do not have a comparison, but there is a review on YouTube by Christopher Frost, and it alone made me not want to bother with it as a manual focus lens. It does not seem all that sharp wide open.

Yes, apparently its an old type lens formula that sacrifices sharpness for smooth focus transitions when wide open. I've seen images and the bokeh is wonderful at full aperture but that wouldn't worry me, as I'd use it tripod mounted on a K1ii for landscape, at f/5.6-f/11 and for that reason the weather sealing also appeals to me.
