I believe there are threads on Pentax Forums discussing using M42 lenses on the K3 III Mono.
@Freakscene I'm curious how you're manually focusing. Are you using the focus indicator in the viewfinder? I do this when I use my manual focus lenses on my Nikon D7000 (which of course lacks any microprism or split image to focus it like a real camera instead of relying on autofocus nonsense). I find it's pretty accurate with my 50mm lenses down to about f/2.8 but is dicey at f/1.4 or f/2.0.
