C.Fn II -1 Tracking sensitivity
[0]
Default setting suited for most subjects. Suited for normal, moving subjects.
[Locked on: -2 / Locked on: -1]
The camera will try to continue focusing the subject even if an obstacle enters
the AF points or if the subject strays from the AF points. The -2 setting makes
the camera track the target subject longer than with the -1 setting.
However, if the camera focuses the wrong subject, it may take slightly longer
to switch and focus the target subject.
[Responsive: +2 / Responsive:+1]
Once an AF point tracks a subject, the camera can focus consecutive subjects
at different distances. Also effective when you want to always focus on the
closest subject. The +2 setting makes it quicker to focus the next consecutive
subject than with +1.
However, the camera will be more prone to focus on the wrong subject.
