Case 3 is the ideal setting for situations when
you want to focus quickly between subjects in

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 photographing skiers in an
alpine skiing downhill race,). Other shooting
situations, this setting can be extremely effective
is when switching between different subjects
you want to shoot (for example, at the start of
a bicycle road race, when you want to shoot
continuously and switch from cyclist to cyclist
while focusing).
When set to Case 3, if the subject moves away
from the AF points, the camera may quickly
refocus on a different subject or background, in
contrast to Case 2. Therefore, it is recommended
that you use this setting only when you have a
particular objective as indicated above.
