Case 3 is the ideal setting when you want the
AF system to focus instantly on any new subject
within the active AF area. In Case 3, the
[Tracking sensitivity] parameter is set to [+1].
As a result, subjects that come into the AF
points will be focused on more quickly. This
setting is most effective when subjects appear
suddenly in the frame (for example, an alpine
skier bursting over a hill and suddenly appearing
i n y o u r v i e w f i n d e r ) . C a s e 3 c a n a l s o b e
extremely effective when you want to instantly
switch from one moving subject to another (for
example, at the start of a bicycle road race,
when you want to shoot continuously and
switch from cyclist to cyclist while focusing).
With Case 3, unlike Case 2, if the subject
moves away from the AF points, the camera will
quickly refocus on a different subject or the
background. Therefore, Case 3 is recommended
only when you truly want the AF to instantly
refocus on new subjects.
