I think we are agreeing here.  But I am saying that I rarely use
Aperture Priority, no matter what kind of lens I use.  That is why the
current kludge is adequate for my needs.  I am not saying it wouldn't
be better to have the option, just that I would almost never use that
option.  I realize others may be different, but this could be one big
reason why many good photographers are not as frustrated by Pentax's
choice here.

It is sort of like saying that Pentax doesn't have the best AF system
in the world, but since I don't really push the AF and don't use it
much, that is not a big problem for me.  For someone like Herb, this
is a big issue.  So some on the list may not see mediocre AF as an
issue just like I see mediocre support for K/M as not a big issue for
me.

So to summarize - Pentax does not offer what it could/should with K/M
support.  That is, they only offer HyperManual when they could have
offered both HyperManual and Aperture Priority.  For those who
want/use aperture priority, this is a big deal.  For those, like
myself, who do not use Aperture Priority, but do use HyperManual
heavily, the support provided is generally adequate and not something
to get worked up about.

Can Pentax do better?  Yes, they could bring back full support of K/M
lenses.  Hopefully they will on a higher priced body at least giving
the option of using it.  If they don't, then there are a certain
number of photographers that will be left out in the cold and
frustrated.  I will not be one of them, however.

Ironically, the place Pentax is hurting much more is not in K/M
support, but in AF performance (tracking, low light) and image
stabilization.  These two areas cause a far greater loss of sales than
the K/M issue.  It remains to be seen if/how they will address this
problem.  And yes, the cost to address the K/M issue is almost nothing
compared to the AF/IS problem.
