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.
