Thanks for the reply.
I would only take this lens apart as a last resort.
Unfortunately, right now i cannot test my super-tak with this adapter because it has been disassembled comepletely for regreasing and aperture blade cleaning.
As i remember when i focused with my super-tak mounted on this same adapter on the post office across the street the distance read beyond 10 meters (close to the start of infinity),
where focusing with this s-m-c 50mm roughly from the same position on the post office reads very close to 5meters. Everything beyond that, as i have mentioned earlier is out of focus.
As i recall, previous owner used this lens on canon 60d and sony a7s.
What is the cheapest adapter that works 100% on all m42 pentax lenses ?

The best thing to do is use the genuine adapter. If your focus ring turns all the way to infinity, it's not likely to be a problem with the lens.
Thanks for the reply, Adam.
The lens is screwed all the way on the adapter. If i would to go any further i only might break something.
Dont know if the adapter is genuine or not, but there is writing on the outer ring which reads "M42 Pentax K/M".
The focus ring is smooth and turns from 0.45meter to infinity with no problem.
