Recommended AF Settings by Event
Instant AF-Area Mode Selection
For flexible AF-area mode selection
when photographing the start of a
race, select single-point AF with the
camera and assign group-area AF
to the focus function buttons using
Custom Setting f1 (Custom control
assignment) > S Lens focus function buttons
(page 26).
You can then press a focus function button to select group-
area AF when your subject is diving from the starting block
and release the button once the swimmer is in the water to
instantly switch to single-point AF without taking your eye
from the viewfinder. AF-area mode can also be assigned to
the Pv, Fn1, Fn2, or AF-ON button, to the center of the sub-se-
lector, or to the AF-ON button on the optional MB-D17 battery
pack (page 24).
