When used with an EOS-dedicated Speedlite: With
the
540EZ
(which can emit a focusing point-linked
AF-Illuminator). the Speedlite's AF-Illuminator is
emitted instead of the camera's.
With other EZ-series Speedlites and the 160E, the
camera normally emits the AF-Illuminator. The
Speedlite's AF-Illuminator is emitted instead only
when the center focusing point has been selected
with the Main Dial.

The camera's AF-Illuminator can be disabled. Doing so
also disables the Speedlite's AF-Illuminator.
The AF-Illuminator is emitted automatically for low-con-
trast subjects.
