Pentax K=mount lens'
You may be aware, but "after a fashion" you CAN adapt (import adapter) use screw mount on a K mount body. Also don't forget the old Tamron Adaptall II stuff. Some of those are "pretty fair" lenses, although they don't have anything wide and fast that I'm aware of.

THIS was taken manually focused with an old Sears / Mamiya on my old Canon XT, a 55mm f1.8

If you have not done much of this, keep trying. It can be difficult to get a good sharp focus. The reasons are several
On the cheaper line cameras (my old Canon Xt) the viewfinder is small, and uses a mirror, not a prism
So far as I know ALL these fancy new cameras have a partially transparent mirror for the metering system. This cuts down on the light to the viewfinder
On crop cameras, especially, the multiplication of the crop factor adds to the problem
Last, the fact that we now routinely take huge photo sizes and display them on very large displays shows up every error, LOL
The above problems are largely why I graduated to my 40D and later 7D bodies. Increased viewfinder size, better viewfinder optics, and a much much larger rear screen with magnified "live view" which has been a TREMENDOUS help for landscapes, etc
This was taken with an Olympus 28mm f2.8, probably stopped down to around f16, using my 40D
