Hi all,

I'm new to the list but I've been reading the archives for the last few
weeks so hopefully I will not make too much of a fool of myself.  I'm a long
time amateur user of Pentax 35mm film gear about to buy my first DSLR. I was
minutes away from buying a K100D when the K10D was announced...

I have a lot of manual-aperture K-mount glass, so being able to use it on
a new DSLR is important to me.  I know there are workarounds for using
such on the K100D but they're pretty bad (metering on DOF-preview only
and/or manually setting aperture to match the lens's).

The dpreview page (http://www.dpreview.com/articles/pentaxk10d/page2.asp)
and a few other verbatim copies thereof explicitly says 
"Ability to use lens aperture ring" so I was very excitted to think that
Pentax would have finally fixed this (idiotic) design error on the K10D.

But, the press photos of the K10D clearly show an absence of a mechanical
aperture coupling lever.  And the (mis)released manual from a couple of
days ago documents the same behavior as the K100D.  Can anyone confirm
this for sure one was or the other?

Also, can anyone explain to me why the K100D (and apparently the K10D) disable
(a) non-central AF sensors (for focus confirmation, not AF, obviously) and
(b) all the metering modes except CWA when using a pre-A lens?  I cannot
conceive of any possible reason these features would care about the lens
aperture being set manually.

Thanks!
David Bliss
