AF-assist beam firing
The AF-assist beam can be emitted by the camera's built-in flash
or
by
an
external, EOS-dedicated Speedlite.
0:
Enable
1: Disable
The AF-assist beam is not emitted.
2: Enable
external
flash
only
If
an
external, EOS-dedicated Speedlite is attached, it will emit the AF-
assist beam when necessary.
3: IR AF
assist
beam
only
Among
EOS-dedicated Speedlites, only those
which
have
an
infrared AF-assist
beam
will
be
able
to
emit
the
beam.
This
prevents
any
Speedlite
which
uses
a
series of
small
flashes (like
the
built-in flash)
from
firing
the
AF-assist
beam.

If the external, EOS-dedicated Speedlite's [AF-assist beam firing] Custom
Function
is
set
to
[Disabled], the Speedlite will not emit the AF-assistbeam
even if the camera's C.Fn
III
-11-0/2/3
is
set.

The AF area selection mode
and
manually-selected AF point (or Zone selected

be
set separately for the vertical and horizontal orientations.

Zone selected with Zone AF) are used for both orientations.

different

selected with Zone AF) can be set separately for each camera
orientation (1. Horizontal,

instance, you want to keep using the right AF point during all camera
orientations.

with Zone AF) for each camera orientation
(1.

and manually-selected AF point (or Zone selected with Zone AF) to suit
each camera orientation.
