so my understanding of ai servo is that if you have all focus points active for the function to work correctly you half press to focus on the centre point and then the camera will continue to track subject as long as it stays within the af points (?)
am wondering when using ai servo a couple of things:
if i select an af point manually that is not the center, will the camera track from that af point (if it's not a 7d)? or will it still be tracking the object from the centre point even if i manually choose to select an off centre af point?
or do i need to just accept that fact that i'll have to use centre af point, track subject and crop later for the composition i would prefer?
