Hello. It's my first post and am asking for your help on what may be a fairly basic question.
I have a 7D. I have the custom functions set so that the "AF-ON" button in the back is my focusing button (not the halfway pressed shutter button -- that has been disabled).
I have some questions re: AI Servo.
1) Do I need to keep the "AF-ON" button pressed the whole time I am shooting?
2) If I start the subject (with the subject in motion) focused (using expanded focusing -- the five squares) -- if I want to place the subject (for compositiional reasons) outside the 19 focusing areas, say at the extreme side, is the AI Servo still able to follow the subject? If it can be done, how would I do it? Do I still keep the "AF-ON" button pressed the whole time even if my subject is not near the focusing squares?
Sorry if this is very basic. Would appreciate your help.
