AF is amazing .. even when AI Servo and AI Focus were set with extreme lateral focus points ;)

All photos were taken with 5D Mark III with 70-200/2.8 L

16 hi-res action images from Cross Country - http://www.flickr.com/photos/piotrczechowski/sets/72157629710911017/

12 shots burst

PS. Wish buffer wasn't so narrow ...

This is why understanding the sport you shoot is everything. The shots with all the dirt in front are killer! Seriously good!

Re: Canon 5D Mark III - AF servo vs Cross Country [pics!]

I like I like! I'm wondering as well about more details to the AF settings since I need to learn a lot about the new focusing system used in 5DIII... for example, how was your settings to start focusing? Single point, zone AF and so on.... I guess for faster moving objects zone AF would be suiting, right? Does anyone know what happens if the tracked object gets out of the zone that was set in AF Zone? Will it still be tracked by the other AF points? Thanks for your help!

Edit: Forgot to tell that I've been looking in the manual already for answers but I haven't found it specified there. Maybe it's there but I didn't find it...

Thanks! I always try to think before press the shutter button even when things are happening really fast.

What did your Ai Servo settings look like?

There was AI Servo and AI Focus as well. Both doing well.

looks fantastic!

what percentage of shots were missed (oof)?

It's hard to tell. Usually there was from 4 to 7 shots OK from 12-15 burst. Biggest issue is not focus - it's the small buffer ... with 6fps it's so so so narrow ...

Amazing!
I shoot Moto-GP and when they move towards you it's almost impossible to keep focus. Instead I always shoot then in the corners (or going in/out of corners) where the focus hardly changes.
I can't wait to get my 5D3.
