If anyone is interested, I have a 90° eyepiece that will lock onto any
of the Adaptall ][ lenses without the adapter, giving you a (fill in
your focal length[s] here) spotting scope or telescope. Best offer
over $25. It's really nice. With case. I've used it with my 80-200
with great results when I wasn't there for photography. Bright image
too!

Because the screwdriver is there on the adapter, but there's
nothing in
the lens to adjust. I don't want the camera body trying to turn
something it can't to find out if anything adjusts.
And yes I could set the camera body to MF before mounting the
lens, but
forgetting should not have dire mechanical consequences.
It doesn't. I use M series lenses all the time on my DL2, leaving
AF on so that I can use focus confrim and trap focus. Been doing
that for just over three years and for another mumblemumble years
with my Z1-p. I cannot see any marks on my lens mounts at all.
With the Adaptall 2 adaptor, there's a lens, and then a mount-
specific
adaptor. If the lens is pure MF, and the adaptor -- because that's
what
one can get off ebay -- supports auto-focus, the camera has
absolutely
no way to tell that the screw drive isn't connected to anything.
No Adaptall mounts support AF. There are 2 versions for K mount, one
is plain K and the second is KA (but not 100% KA, as aperture
reporting via contacts is only accurate within certain limits). Some
Chinese clones also exist, but are essentially uncoupled preset
adapters that are really an uncoupled M42 mount on a M42-K adapter.
AF confirm Adaptall adapters exist for other mounts (but are the same
chinese uncoupled stacked m42 setup) but those only enable AF confirm
(and Av mode on some Sony bodies).
