thank you!

.....& out-takes too! I'd love to see a proofs of all the
shots,...not just the ones you decided to post to show the glory of
the 5D's AF performance at f4 at 1600 iso, and 125ths....which is
what I would call, good light!

BTW, couldn't you have shot a little tighter..?

Try shooting at 1/30ths at f2.0, with a 135mm f2.0 L, 5D, 1600iso
with reliable AF, of a subject moving around the outside of the stage
that they made for him to walk around on,..but didn't.. and instead
chose to walk around the dark table seating areas instead! Regardless
of my lousy tools ..(the 5D), I had to shoot this low contrast large
guy against a sea of people with more contrast than him! .....kind of
like the opposite of your "sucky" photos.. In some spots the
table seating was brighter than him, who is wearing all black,....and
then brag about how great the AF of the 5D is!

I used Manual focus because the AF of the 5D was giving me nothing
but mush!:

P.O.S. 5D AF if you ask me!

I can nail your type of shot easily with my 5D. All I saw was a big
guy standing. This guy can't be moving that fast. My mages show more
activities than yours. Next time use your flash to focus without
firing it.

That's because he paused.. He would walk from one end of the room to
the other, and then he would pause for about 1/2 a second tops when
he concluded his point, and then resume walking in the opposite
direction. He was not standing still posed for me, nor standing in
one spot.

I guarantee you'd not be able to consistently nail those shots with
the 5D's AF. In addition to that, 3200 iso was off limits because my
clients doesn't like 3200 iso results from my 5D, so your f2.8 would
be shot at 15ths.. good luck! & flash was not an option. In addition,
the red light emitted by the flash would have been distracting, which
he wouldn't have wanted.

I definitely agree with you and your opinions on the 5D AF. The red AF assist light might not help you even then - I was doing some low light shots (flashed) with my 30D at short range with fast prime, and even with the AF assist, the accuracy was barely usable with the center point (and I had to focus recompose for the non-center framed shots) - there were a lot of OOF shots. Outer AF points couldn't even lock with the AF assist. So the AF assist might not save you even if it was accepted.

Now,...lets see you do it!

Certain people will try to hint that you'd need that "sports" camera. :-/
