But we've just been discussing the exceptions!! These may have post dated
your post so to summarise: Pentax have modified the mirror box by taking
some of the space for Power zoom bits even if the camera does not support
PZ. This means that SOME older Vivitar lenses will NOT mount on Pentax
autofocus bodies (and the MZ-M) which came after the SF series.

YES but it is not broken - it is in the design. When the lens was made it
fit all K-mounts. Pentax have modified the shape of the mirror box on later
cameras.

See above - It will NOT mount.
Trying to fit these particular lenses MAY DAMAGE YOUR CAMERA. If you read
the whole thread someone has reported damage to the mirror in LX cameras and
speculates that the damage is caused by such lenses.
If my use of capitals seems rude sorry Stan I wasn't shouting - just trying
to emphasise points which we have established as you appeared to be giving
advice without the awareness of other comments on this particular issue.
It would be useful if we can pool our knowledge to establish exactly which
lenses are affected as we appear to have identified at least 2 now.
One is the Vivitar Series 1 70-210mm F3.5 macro with 67mm Filter thread.
One is the Vivitar Series 1 28mm f2 (more details Tanya?)
Any more?
