Case 2 is an effective setting for shooting fast
moving subjects when they move away from
the selected AF point, or when obstacles may
momentarily obscure the subject. Sometimes
when the subject moves from the selected AF
point, focus can shift to the background
(resulting in an out of focus subject), similarly
when an obstacle obscures the subject, focus
can shift to the obstacle. By selecting Case 2 in
situations like these, focus will attempt to
continue to track the desired subject. When a
subject moves away from the AF points for an
extended period (such as swimmers doing the
butterfly stroke, or sports where the subject is
hidden for intervals), even better performance
may be achieved by manually setting the
[Tracking sensitivity] parameter to [-2].
