Hi
I have a K100 and bought a PK-mount macro lense but it didn't deliver the magnification I needed. I found this thread and probably didn't read it right as I then bought some M42 tubes and an M42-to-PK body adaptor.
The issue is that the adaptor allows me to connect the M42 tubes to the K100 body....but I can't attach the PK-mount lenses to the tubes!
I've searched the web to find an adaptor that allows me to attach my PK-mount lense to the M42 tubes, with no success.
Any ideas anyone!!?

What you need are K-mount tubes.

You can use screw mount tubes and lenses on a K-mount body via the adapter, but not K-mount lenses on screwmount bodies (without some serious modifications).

If you need more tubes, just buy more PK macro tubes and stack them on top of the others.

That mount only allows for m42 lenses / macro tubes to be attached to the body of the camera with a PK mount.
I doubt there is such a thing as a mount from PK macro tubes to m42 macro tubes (and vice versa)...
