AF point auto switching [+1]
Case 5 is most effective for subjects with large
amount of movements which could occur in
any direction. This setting works in 65-point
automatic selection AF, Zone AF, and AF point
expansion modes only. In Case 5, [AF pt auto
switching] is set to [+1], when the subject
moves away from the manually selected AF
point (AF points focused on initially with Zone
AF), focusing automatically switches to other AF
points that contain the subject. As a result, even
when the subject continuously leaves the
selected AF point, it is possible to increase the
ratio of photos that are in focus. This setting is
most effective when shooting subjects with
erratic movement such as figure skating,
badminton, skateboarding, and inline skating.
