There's a lot of confusion on the two settings in subject, as most people I am talking to either believe that they are the same thing (where "Whole area tracking Servo AF" is the global setting and "Start/Stop Whole Area AF Tracking" is a way to temporarily override the general setting by the press of a button) or believe "Start/Stop Whole Area AF Tracking" does the wrong think.
I read the Canon manual (too cryptic too often) and I have made some testing, and came to the following conclusion:
- Whole area tracking Servo AF
- it is a global menu option
- can be assigned to personal menu
- cannot be assigned to a button
- when ON, the tracking of a subject continues even if the subject exits the AF points/area
- Whole Area AF Tracking
- it is not a global menu option (nowhere to be found in menu)
- cannot be assigned to personal menu
- can be assigned to a button
- by default it is OFF and on the screen you see the AF point/area of your choice; in case of whole area AF detected subject are shown with a single-line square to indicate subject tracking is off (with left-right arrow to switch subjects)
- pressing the button, enables tracking in whole area AF mode: a little double-lined square is shown on top-right of the screen with an OFF label, the screen turns into whole area AF and detected subject are shown with a double-line square to indicate subject tracking is on (with left-right arrow to switch subjects)
- somehow (still investigating) if onn, this turns off automatically if no subjects re detected
Am I correct? Missing anything?
thx
