that won't be happening - (friend taking picture)

I'll just have to wait to get it in person

Intereasting, though - in the photos for the Pentax K there is no red
dot. - all the lenses I have  have them.

Looks like it's an 'A' lens that's not locked in the 'A' position.

The red dot is there on the side of the bayonet. If you follow the vertical side of the letter 'P', you can just barely see it (or its reflection) right under the edge of the flange.

Thanks JOhn... that was what I wondered.  I'd have no way to test it

selling unless I could put it on one of my bodies, or pay to have it

is the only SLR with clue to positioning the lens to body for
mounting
or are there several?

I didn't see it, this was me asking questions over phone but I
figured
Bayonet mount, good zoom - worth checking out more anyway.

Every K-mount Tokina lens I've had, the red dot on the rear flange
was in the right place.


That's not the question Ann had, though.

My Olympus 4/3 lenses have a bayonet mount, and a red dot for
positioning.

I would not be at all surprised to find that there are other systems
that
also have red dots, so even though the Tokina 28-810 lens has a bayonet
mount and a red dot there is no guarantee that it is, in fact, a
K-mount.
