My understanding in Chuck Westfall's technical writeup on AI-Servo
info, that the first frame of burst mode using AI-Servo does not guarantee sharp focus due to Canon's design of Release Priority of the EOS system.
And the paper goes on to say that subsequent burstshots are Focus Priority, ie, to say that, the camera won't fire until it achieves a good focus based on the 6 conditions.
Does it imply that:
(1) using C.Fn4-1, I can always get a tack-sharp first frame, ie, keep pressing the * button while aiming at the subject until i press the shutter release button?
(2) depending on the 6 conditions, i may not achieve the rated fps?
Thanks for ur inputs.
