Setting AF subject tracking
You can select the tracking sensitivity used
by auto focus.
1 Press the MENU button D , and select
(CAMERA SET) t [AF SUBJ.
TRACK SET].
2 Set [AF TRACKING DEPTH] and [AF
SUBJ. SWITCH. SENS.].
AF TRACKING DEPTH:
This sets the range for tracking subjects in
the depth direction in the range
[1[NARROW]] to [5[WIDE]].
The wider the range, the faster the response
to subjects with large motion, allowing
focusing on subjects with different
distances one after the other.
The narrower the range, focusing can be
maintained on subjects with less movement.
This is useful to maintain focus on a subject
under conditions where other subjects may
pass in front of the intended subject.
AF SUBJ. SWITCH. SENS.:
This sets the time taken for focusing on a
new subject when switching subjects in the
range [1[LOCKED ON]] to
[5[RESPONSIVE]].
The shorter the time, the faster the response
to changing subjects, allowing focusing on
different subjects one after the other.
The longer the time, the longer the focus is
maintained. This focus response delay
allows you to maintain the focus on a
subject if the subject is temporarily placed
outside the focus area and then immediately
returned to within the focus area.
