Part 1: General Information

lock button and focusing point selector simultaneously.
* The calibration settings cannot be deleted all at once. They
must be deleted individually under each CAL No.
(2) Automatic focusing point selection
Automatic focusing point selection is set when you try to select a
focusing point beyond the outer-most one during manual focusing
point selection.
1) One-Shot AF: Based on the subject information obtained by the
seven focusing points, the camera focuses the optimum subject
automatically.
* With the Eye Control switch turned ON in the Full Auto mode, the
eye position is detected automatically and this information is
incorporated in the automatic focusing point selection algorithm.
This increases the chances for the camera to select the focusing
point that the user wants.
2) AI Servo AF: AF starts with the center focusing point. If the subject
moves to another focusing point, AI Servo AF continues to track the
subject. (The active focusing point switches to the next one.)
3) AI Focus AF: The One-Shot AF mode focuses the optimum subject
based on the subject information obtained by the seven focusing
points. If the center focusing point focuses the subject first and the
subject starts to move, the AF mode switches to AI Servo AF and the
subject is tracked even if it moves to another focusing point. Only the
center focusing point can detect initial subject movement. (If an off-
center focusing point first focuses the subject, any subject movement
will not be detected.)
