Herb,

I was just in a pissy mood last night, I think.

I know how hard it must be to do what you're doing and nail down the focus of moving animals with the aperture wide open. Actually, I don't know, because I've never tried it. I can imagine it's difficult, though.

As I indicated in my original post, many of the photos I did like, even ones where the focus was off just a tad.

Just ignore me when I get that way.

cheers,
frank

manual focus wide open on a long lens. at 50 feet, the DOF is a couple of
inches, barely a wiggle on the focus ring and very hard to see in the
viewfinder. mostly, the subjects are moving and i can't move the focus ring
fast enough to keep up. AF would have caught the right point, if it were
available. i'm shooting at longer ranges and smaller subjects. i had about
10 seconds to aim my camera and focus before the beaver dived. i think my
percentage would have been higher with AF. 10 seconds is the typical time i
have to aim and focus before the subject has moved enough to require moving
and refocusing. the swan and turtle pictures are where i could have stopped
down to f5.6 and gotten a little more DOF. otherwise, the shutter speeds
would have been too low and i would have gotten vibration blur. image
stablization is something i am looking forward to.
