And let's not forget the Nikon PN-11 originally made to take one of the
earlier Micro-Nikkors out to 1:1 as I recall. It is a 52.5mm auto
extension ring complete with an integral tripod mount.
Extremely useful with any current Micro-Nikkor (and others) to extend the
reproduction ratio. I find it works especially well with my 200mm
Micro-Nikkor when paired with the RRS 87-B mounting which locks the whole
shebang into one Arca-Swiss quick-mountable unit. The 87-B also can act
as a focusing slider, so you don't have to play with your reproduction
ratio during focus.

I have a PN-11 (and maybe a suitable RRS plate) available
if anyone is interested...

This would be a sweet setup:

I don't think I'd be up to the modification though. But to be able to have
metering, AF-S & VR on my 105 & 70-200 and strong enough to hold the
Tamron 300/2.8 AI

I have a Manfrotto quickmount & 2 plates (which I'm not real happy with).
A mount on the tube would be smart for macro work, is the Arca-Swiss the
only option there?

Paul:
I'm not sure that 7 electrical contacts would be enough for AF-S & VR
both with the 105 setup. I doubt the glued (epoxy, to be sure) contact
mounts would hold up to much normal (rough?) handling. I would not want to
trust the PN-11 contacts not to come apart while mounted to the camera. Can
you imagine the damage that would cause?
I've never had any problems with metering on the F5 and either of the D2
bodies with the PN-11 attached to the AF Micro Nikkor 200mm 1:4 D with
ambient, constant artificial or flash TTL illumination.
With the 105, you wouldn't need the 87-B plate as it's made specifically
to anchor the two tripod mounts (the PN-11 and the 200 Micro) together in a
solid package and still allow lens rotation in both mounts.
Without the plate you could use the normal tripod mounting hole (1/4X20)
in the PN-11 mount as you would with any ordinary mount.
I don't think the PN-11 has been made for some time.
