Standard setting suited for any moving
subject. Works with various subjects and
scenes.
Select [
Case 2 ] to [ Case 6 ] for the
following: When an obstacle cuts across
the AF points or the subject tends to
stray from the AF points, when you want
to focus on a subject appearing
suddenly, when the speed of a moving
subject changes suddenly, or when the
subject dramatically moves horizontally
or vertically.
The camera will try to continue focusing
on the subject even if an obstacle cuts
across the AF points or if the subject
strays from the AF points. Effective when
there may be an obstacle blocking the
subject or when you do not want to focus
on the background.
Case 1: Versatile multi purpose setting
Default settings
• Tracking sensitivity: 0
• Accel./decel. tracking: 0
• AF pt auto switching: 0
Case 2: Continue to track subjects, ignoring possible obstacles
Default settings
• Tracking sensitivity: Locked on:
-1
• Accel./decel. tracking: 0
• AF pt auto switching: 0
If an obstacle gets in the way or if the subject moves away from the AF
points for a prolonged period and the default setting is unable to track the
target subject, setting [
Tracking sensitivity ] to [ -2 ] may give better results
(p.132).
