Wait for that
exact split second when you anticipate the action is going to provide the best capture out of, say 50 possible outcomes?
Sorry, but I don't buy that way of thinking.
Sounds to me like landscape photographers waiting for the precise time when the sun is just setting behind a mountaintop. Or a studio photographer with his/her lens trained on a model's face waiting for a natural-looking smile to cross the lips of his/her subject.
Even that doesn't always hold true, though. Ben has admitted taking approx. 500 shots in 10 minutes during a shoot, so even fashion photogs shotgun at times.
For nature (and presumably sports) photographers, I don't believe there is such a thing as too high a frame rate, or too large a buffer, or too fast AF. Anticipating that split second when a bird, flying by at 30mph, turns its head and makes eye contact? Sorry, I couldn't do it if my life depended on it.
