Originally posted by PenPusher I suppose Murphy's law had to strike sometime.
I was demonstrating to a friend how easy it was to use M42 lenses on his K-r and fitted my genuine Chinese M42 adapter to his camera and successfully demonstrated several m42 lenses, and naturally the adapter is now stuck firmly on the camera, any body know how to get it off, I've tried 2 different spanners without luck.
I have used it frequently on my K70 without problems.

Oh no!
I have two, the original Pentax, and a Kalt NOS that uses the spanner. Generally it's just as easy to use either one, but it is a little fiddly when I haven't used the Kalt in a while. I'd slow down, relax, and try the same method that's worked on your cameras again before trying anything else.
