Equal priority
This setting gives an equal priority to both focus and shutter-
release, for the first shot in an AI Servo AF sequence.
Release priority
For first image in a sequence, priority is on firing shutter — even
if sharp focus isn't confirmed. It is effective when you want to
minimize any delay when shooting, sacrificing AF performance.
Focus priority
For initial shot in a seqeunce, in AI Servo AF, camera won't fire
until sharp focus has been confirmed. It is recommended when
you want to ensure your images are in focus, even at the cost
of added "lag time."
