I have personally held an SMCA* 85/1.4 Lens that was modified for use on a
Nikon. The approximately 1 millimeter was added to the back of the lens via
a modified or constructed Nikon mount that was affixed to the back of the
lens in place of the Pentax mount. The mount stuck out a little from the
back, I believe. I was told a little old German guy who used to have a
little shop on Wilshire Blvd., California did the work. If it's the same guy
I visited years ago, he was certainly qualified to do the work. He used to
modify lens mounts for use on movie cameras too, I believe. He's passed on
now...
Regards,
Bob...

1mm out!
and going the wrong way. Well if I couldn't mill 1 mm off the back of a
Limited, and stick a Nikon flange on, my name's not Dr Frankenstien.

Don't you have something here backward?
OOPS
Sorry, brain not engaged (when is it?).
Peter is right - the difference is 1mm but going the *right* way. That
means that instead of taking off 1mm from the back of a PK lens, we need
to add 1mm to it, so that it focusses at the Nikon register distance.
This is *much* easier to do.
The problem will be in the adapter - 1mm is awfully small for an adapter
thickness so that it maintains structural integrity (love those Star Trek
buzzwords).
What is remove the Pentax mount, fashion a Nikon mount with new mounting
holes, and add a 1mm spacer ring inbetween, using longer screws. That's
very doable.
Is there space for the aperture lever in a Nikon body? Probably not, so
that bugger will saw right off no problemo.
I'll look around and see if anyone's done it.
