Optional Accessories
Designated External Flash Units
When using an optional fl ash unit designed for use with the camera, you can choose
the fl ash mode using camera controls and take pictures with the fl ash. See the
documentation provided with the fl ash unit for information on fl ash features and their
use.
Choose a
fl ash unit to suit your needs, taking into consideration such factors as
the output required and whether the unit supports macro photography. Flash units
designed to communicate with the camera support a variety of
fl ash modes, including
TTL auto and super FP. Flash units can be mounted on the camera hot shoe or
connected using a cable (available separately) and
fl ash bracket. The camera also
supports the following wireless fl ash control systems:
Radio-Controlled Flash Photography: CMD, # CMD, RCV, and X-RCV Modes
The camera controls one or more remote fl ash units by means of radio signals. The
range of locations in which fl ash units can be placed increases. Flash units can control
other compatible units or be fi tted with radio commander/receivers to allow the use of
units that do not otherwise support radio fl ash control.
Wireless Remote-Control Flash Photography: RC Mode
The camera controls one or more remote fl ash units by means of optical signals. The
fl ash mode can be selected using camera controls (P. 105).
