I am completely tuned into this thread and very anxious to see what others have to say! I have been trying to capture alot of running toward me shots of my dogs and just having nailed them as consistently as I would like to! My best ones were taken with primes but of course, I missed the shot many times due to their lack of versatility ...my legs just aren't as quick as my dogs!

I just went through some of my action shots of the dogs and none of them were taken with the 70-200mm f/4 IS. I'm not saying I never took them with that lens, they just must have not been keepers.

If I could get shots like these out of a zoom, I would be happy!
