Boy, you have me confused. I have shot a lot of weddings, and I don't
recall action shots being a part of it. If you can't focus follow someone
walking down the aisle, then perhaps you might consider that action.
I never use AF for weddings.
The istD seems to have a very steep AF falloff, it goes from quite good (my experience is limited, I admit) to totally useless within about 1EV of light.
He was using AF-C, which is a great way to get out of focus images.
