Wireless remote control ash photography
External ash units that are designated for use with this camera and have a remote
control mode can be used for wireless ash photography. The camera can separately
control each of three groups of remote ash units, and the internal ash. See the
instruction manuals provided with the external ash units for details.
1
Set the remote ash units to RC mode and place them as desired.
• Turn the external ash units on, press the MODE button, and select RC mode.
• Select a channel and group for each external ash unit.
2
Select [On] for [# RC Mode] in X Shooting Menu 2 (P. 118).
• Press the Q button to exit to the RC mode display. Press the INFO button to cycle
between LV super controls or live controls and the RC mode display.
• Select a ash mode (note that red-eye reduction is not available in RC mode).
3
Adjust the settings for each group in the RC mode display.

 Wireless ash control range
Position the wireless ash units with their remote sensors facing the camera. The following
illustration shows the approximate ranges at which the ash units can be positioned. The
actual control range varies with local conditions.
• We recommend using a single group of up to
three remote ash units.
• Remote ash units cannot be used for second
curtain slow synchronization exposures longer
than 4 seconds.
• If the subject is too close to the camera,
the control ashes emitted by the camera
ash may affect exposure (this effect can be
reduced by reducing the output of the camera
ash by, for example, using a diffuser).

mode.
