I have configured my 5D3 to operate back button focus with the "AF-On" button.
If I want to use AI Servo AF to track fast moving subjects, do I need to keep the Back button (AF-On) button pressed throughout the duration of the shot sequence to keep focus
or do I need to reconfigure the back button focus for this mode
or does the back button setting revetrt to the shutter button in this mode?
Any Help appreciated
