The data I posted below was completely wrong. I was thinking of another
shot. I checked the metadata and this shot was 105mm, f8. F5.6 might
have been better, but it might also have been too shallow at that long
a focal length.

I agree, nice shot. I also think it might have benefited from less
depth of field. Generally, the depth of field for any given lens and
stop is the same on the *ist D as it would be on a 35mm film camera.
However, the field of view is different. Thus, a lens on the *ist D
that gives you field of view equivalent to a 50mm lens on a 35mm film
camera will give you the depth of field of a 33 to 34mm lens. I don't
find it to be much of a problem. With 1/4000 shutter speed I can
usually get a wide enough stop to narrow the dof sufficiently. I just
posted a PAW
(http://www.photo.net/photodb/photo?photo_id=2407739&size=lg) that I
shot with the FA28-105/3.2-4.5 at about 45mm focal length. I
definitely didn't want the messy background across the street to be
sharp, so I shot at 5.6, which is close to wide open on that lens. If
I had better glass on my camera, I would have opened up some more.

I like that one, Bruce. It catches a nice moment ;-))
One of the things I'm starting to notice with the pentax, and some
other
DSLR's, is the excessive DOF that sometimes encroaches on what might
otherwise be an excellent or exceptional photograph. I'm not
specifically
criticizing your pic, and I'm not sure I'm even criticizing the way
these
digi cameras work, especially with lenses that don't provide
particularly
shallow DOF to begin with, however, it's an observation that your pic
motivated comment upon. Personally, I'd have liked a little less
sharpness
from the guy in the back, yet it doesn't always seem possible to
control
the DOF on the shallow end with these cameras. I'd love to hear some
comments about this.
