Lens for dog agility / action

[Busted Knuckles]

And even more here:
(a beat up old 300D with an 18-55mm kit lens will focus faster on a contrasty starburst focus target than 1D IV with 400/2.8 II will focus on an elephant in the fog at twilight).

I have no dog in this debate (grin) just thought Neuro's comment was worth a second telling for the humor.

I'm not a huge cross processing fan, but I really like the second shot of Zuni. Great action shot.
