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.
