C.Fn III -2     AI Servo 1st/2nd image priority
For the AI Servo AF and continuous shooting modes, you can change the 
Servo’s operation characteristics and shutter-release timing.
0: AF priority/Tracking priority
For the first shot, focusing the subject is given priority. For the 2nd and 
following shots during continuous shooting, focus-tracking of the subject 
is given priority.
1: AF priority/Drive speed priority
For the first shot, focusing the subject is given priority. During continuous 
shooting, the continuous shooting speed is given priority over the focus-
tracking of the subject.
2: Release/Drive speed priority
For the first shot, shutter release is given priority over focusing the 
subject. During continuous shooting, the continuous shooting speed is 
given priority more than with setting 1.
3: Release/Tracking priority
For the first shot, shutter release is given priority over focusing the 
subject. For the 2nd and following shots during continuous shooting, 
focus-tracking of the subject is given priority.
C.Fn III -3     AI Servo AF tracking method
In the AI Servo AF mode while you are focus-tracking a subject, the camera 
can either continue focusing the target subject even if a closer subject 
(closer than at the main focus point) suddenly appears in the picture, or the 
camera can switch to focus the closer subject.
* Main focus point:
 
With 19-point AF auto selection and AF point expansion, this is the 
first AF point which started the focusing. With Zone AF, this is the 
active AF point.
0: Main focus point priority
The active AF point will switch to the main focus point and start focusing 
the closer subject. Convenient when you always want to focus the 
closest subject.
1: Continuous AF track priority
Any closer subject appearing in the picture will be ignored as an 
obstruction. The main focus point does not take priority, so the tracking 
of the target subject can continue and switch to an adjacent AF point 
based on the preceding focusing result. Convenient when obstacles 
such as telephone poles go in front of the target subject.
