Using the Commander Mode
When the flash mode (A57) is set to z (commander mode), you can wirelessly
control an off-camera optional flash unit.
• Set the group and channel settings for the remote flash unit to “Group A” and “3
CH,” respectively.
• Place the flash unit within the range shown in the diagram below.
• Set up the remote flash unit facing the camera to ensure that the light from the
built-in flash will enter the wireless remote sensor window of the remote flash
unit. Set up the remote flash unit in a position closer to the subject than the
camera.
• The distances shown in the diagram above may vary depending on the
surrounding environment.
B Notes on Using Commander Mode
• In commander mode, the camera's built-in flash emits low-level flashes in order to control the
flash unit. Therefore, the built-in flash must always be raised when using commander mode. The
remote flash unit fires in accordance with the Commander mode options (E56) set.
• The built-in flash is not usable when it is set to the commander mode.
• Ensure that light directly from the flash unit or strong reflections do not enter the shooting lens of
the camera. It may not be possible to obtain the correct exposure if such light enters the lens.
• If the light of the remote flash bounces and does not directly light a subject, set the Flash control
mode of the Commander mode (E56) to Manual in order to adjust the flash output.
• Aside from monitor pre-flashes, the camera's built-in flash emits low-level flashes during shooting
to match the flash timing of the flash unit. When shooting a subject at close distance, these low-
level flashes may be captured on the image. To prevent such adverse effects, use a lower ISO
sensitivity or a larger aperture value (A49).
• Refer to the Speedlight's instruction manual for more information on flash unit settings.
