I was actually looking for an 85 mm f2 M lens for a while. I didn't need f1.4 or Pentax * quality (and price), but they all ended up either more expensive than the Samyang 85 mm f1.4 or with "the fungus, hazing, and element separation don't seem to be affecting the photos, but I'm selling it as-is" caveat.
I finally caved and bought the Rokinon 85mm, and it's great. Having the auto aperture is really nice. I, too have "old guy eyes", but the rear screen highlights seem to work pretty well even wide open.
The viewfinder focus confirmation is less accurate but works well enough at about f2.8 close in.
