The fact that you could screw your lens into an adapter and use it without any other adjustments?
A pretty poor adapter though - and it would only count as backward compatibility if it was packaged with all the cameras they sold. The adapter is poor because:

- it does not lock on the camera properly. This in turn causes issues because lenses may unlock or jiggle in the mount.
- it does not allow you to quickly remove an adapted lens from the mount.

By comparison, the M42 adapter story is much better on Canon and Sony. I find that ironic given the backward compatibility chest thumping attitude of some Pentax users.

You are acting like people knew where technology was headed years before it was even thought of.
I am only talking about use of M42 lenses - that hardly qualifies as science fiction in 1975.

Actually pre auto aperture lenses are more compliant on Pentax (K mount m42) than the f lenses on nikon. the Ai lenses like the a lenses are fully compliant (but in Nikon's case only on bodies they don't cripple intentionally)
We're talking about Pentax, not Nikon. Just because there is a company that does worse than Pentax, doesn't make Pentax good.
