The AF point was covering the subject in all shots.
But if the AF system finds something more contrasty elsewhere,
that's what
will be in focus.
The system just isn't that reliable.
I know that I could have done this as well or better using manual
focus.
This is exactly my point:
The AF system works fine as long as there's a lot of light and the
subject
doesn't move.
For action photography (where the photographer or/and the subjects are
moving),
when I really want AF, this system is close to useless.
Luckily I'm not a sports photographer and I'm not a professional. If
I were,
I'm certain I would not be using this camera system.

Emne: Re: new AF system soon (when D2 arrives)?
I think, perhaps, you should just sell your Pentax gear and buy
something that will relieve you from having to think about your
photography. You obviously don't understand how the camera works.
There is *something* in focus in most of those photographs (except
for the close up head-shots. Perhaps they were taken at 80mm?).
The fact that it isn't what you would have picked as the focus point
just shows you the danger of using automation without thinking.

Using continous AF and multiple exposure setting and a FA 2.8/80-200mm

exposures.
Is this the fast and accurrate AF-performance a pro photographer or a
dedicated amateur photographer is looking for in a 1500 USD camera:

My *ist D works perfectly normal with an Elinchrome strobe outfit. No
problems.
Some flash units requires, that some cameras (not just Pentax) are
connected
after reversing the polarity of the flash cord.
That's not a real problem. Easily solved, and invovleves several
camera
brands. My camera club just invested in an extra cord, so the
members can
choose the right cord for the right camera.

I agree entirely.
Heck, one can shoot sport without AF at all. I shot a soccer game last
fall with a 200/f4 XR Rikenon and the D, quite successfully. And that
was a bunch of hyperactive 11 year olds.
But There is a major performance gap, and it's one reason I've left
Pentax for AF/Digital bodies. Not the main reason though (That was
logistics. When everyone in the club shoots one brand, having a
different one can cause problems for you at certain events, like
studio
shoots, when you can't take advantage of gear sharing).
