I did. The issue seems to be in the aperture mechanism of the lens.
Stress the lens and the A contact behaves as if the lens has been taken
off the A position. I suspect there's a ground lead in the mount that
has a hairline crack in it. I'd take it apart but my track record of
losing small parts when I do something like that is not good. On a
related note, if anyone would like a video ready Vivitar S1 35-70 f2.8,
(no click stops contentiously variable f stop), lens I accidentally
made, a few years ago, it's price is totally negotiable.

So I've been noticing that the Vivitar 70-210mm will lose contact with the
K-5II more than once in a while. This wouldn't be bad, except in P and M mode
it's like hitting the green button, any aperture or shutter settings are reset
to base. I hadn't noticed this before and I thought that there might be
something going wrong with the lens. It's really very annoying.
Then I thought, what if it's a problem with the K-5II? That would be a bummer,
but at least the Camera is still under warranty. So I mounted the lens on the
K20D and THE K20D WORKS ENTIRELY DIFFERENTLY!!!
The lens has probably always lost momentary communication with the camera, but
the K20D simply goes back to where it was, when contact is resumed. The
shutter and aperture don't reset. Why the hell would Ricoh rewrite the the
code to do this? It makes no particular sense. This issue could surface with
any A lens.
End of rant, you may now resume your regularly scheduled entertainment.
