@candyman: Yes it is quite incredible what the 5D3 auto focus is capable of when correctly configured.
Yes, it is VERY impressive. I had heard that the 5Diii is starting to become a pretty good wildlife camera, and many of the wildlife photographer of the year photos were taken on one. So much so, I am seroiusly considering upgrading to one, but have heard tat the autofocus can be a bit tricky.
Cervantes, could you please spill the beans on how one can configure the autofocus to get shots like this?
