Selecting AF Area Mode
While pressing AF area mode (˝) button,
rotate the Main-Command Dial to select
Single Area AF or Dynamic AF mode.
Dynamic AF is useful when shooting
moving subjects without changing the
composition, or when it is difficult to
predict the position of subjects at the
moment of exposure.
Dynamic AFSingle Area AF
When Dynamic AF mode is selected,
g (or h) appears in the selected focus
area and
f
in all five focus areas of the
top LCD, and all five AF sensors are
active. (Example shows center focus area
selection.)
Using Dynamic AF, you will designate the
primary sensor, the one which will be first
to detect a subject, then if the detected
subject moves, the Dynamic AF operation
will automatically shift to the next sensor
which detects the subject, progressively
shifting among the sensors as the subject
moves; Dynamic AF is capable of follow-
ing and maintaining accurate focus on
moving subjects.
•Viewfinder indication does not change
even though the sensor is shifted in
Dynamic AF mode.
When Single Area AF mode is
selected, you may designate the focus
area you wish to use, and that choice will
remain unchanged regardless of subject
movement. g (or h) appears in the
selected focus area of the top LCD.
(Example is when center focus area is
selected.) You may alternately choose
any one of the five available focus areas.
In Single Area AF mode, the focused
distance is calculated exclusively by the
sensor in the selected focus area.
