M42 and K-bayonet have the same register, and very similar to Nikon
bayonet. That's why there are no adapters I know of that will allow
infinity focus.
There used to be a K-to-M42 adapter that did allow infinity focus. It
contained one or more optical elements to make this work. ...
It's generally a bad idea, though. The M42 mount is smaller diameter
as well as the same register which makes it hard to make this without
also putting a low-power teleconverter in such a mount. That's what
Canon did for the FD->EOS converter ... and IMO it was a total waste
of time.
Probably.
Makes me wonder, though; would it be possible to add some kind of
correction lens that didn't actually magnify?
I've also wondered if the lens mount casting from a K1000 would bolt
onto a Spotmatic.
It's been suggested on this list and other places that the K1000
actually *was* a Spotmatic with replacement mount screwed onto it...
Those cameras were similar enough that it just might
be the case. You'd be limited to stop-down metering, but you'd have an
interesting conversation piece.
Yup. Like the guy who adapted the Leica R bayonet mount to his Nikon
F2 body. Hated the Leica R bodies, loved their lenses, and didn't
care about Nikkor lenses...
He, he. Maybe I'll use the Nikon bayonet ring to make a Pentax F just
for a laugh... Although I think the opposite would make more sense in
some ways...
