OK, people are getting confused here... M42 to Pentax K mount adapters work properly WITHOUT losing infinity focus.
Of course. I just got out my adapter ring, and saw that when installed on my MX, it fits inside a counterbored recess, and the front face of the adapter, and the front face of the lens mount on the camera are flush with each other.

I've done it, on a bunch of different camera bodies, even a borrowed *istD. In fact, if anything, the M42 lens may focus a bit past infinity, depending on how hard you tighten down the adapter ring. All you need is the Pentax M42 to K mount adapter ring. Screw adapter onto lens, mount lens onto camera. Stop-down meter, and shoot. Unscrew lens from adapter, and use fingers/pen/etc. to remove adapter from camera. Lather, rinse, repeat. M42 to Nikon adapters are a different story, and IIRC, Nikon to pretty much anything else requires a teleconverter to maintain infinity focus. -Mat
