I am struggling a bit with the AF of my 5dmk3. Can anyone help?

1. What is the best setting to get a dog coming toward me at full speed? Should I use single spot, all 61 AF points on auto, or the group AF? Say 9 points.

2. How do I lock focus and recompose? Is it not possible if you are shooting AI servo? I assume you have to be AI single?

3. For now, what setting should I have on the custom AF bit? Just case one?


When I shoot sports, I usually use the 9 center points, AI Servo, 6 fps. (I like to use a nine focus points in case the subject jumps away from the single center point.)

I don't see how you can focus and recompose on a dog running toward you, but you could set the focusing points to a different area of the frame.

I generally use Case 2 focusing for basketball, football and baseball--Case 2 ignores the occasional player or obstacle. But if you have a clear field of fire toward the dog, Case 1 might be superior.
