Flash set-up in the Advanced Wireless Lighting
Set up the camera, master flash unit, and remote flash units as shown in the
figure below.
• As a basic guide, the effective shooting distance between the master and remote flash
units is approx. 10m (33 ft.) or less in the front position, and approx. 5 to 7m (16 to
23 ft.) at both sides. These ranges vary slightly depending on the ambient light.
• Be sure to place all remote flash units that are set in the same group close together.
• For the effective shooting distance between the master and remote flash units in SU-4
type wireless multiple flash shooting, refer to page 85.

Setting up the master and remote flash units
• In most cases, position the remote flash unit(s) closer to the subject than the camera,
so that light from the master flash unit can reach the light sensor of the remote flash
unit(s). This is particularly necessary when holding a remote flash unit in your hand.
• Data communication cannot be performed properly if there is an obstacle between the
master unit and remote flash units.
• Take care not to let light from the remote flash unit enter the camera lens directly or
indirectly in TTL auto flash mode. Also, prevent light from entering the master flash unit’s
light sensor in Non-TTL auto flash mode. Otherwise, the correct exposure cannot be
obtained.
• There is no limit to the number of remote flash units that can be used together. However,
if too much light from other remote flash units enters the light sensor of the master flash
unit, correct operation may be impossible. Practically, the number of remote flash units
in Advanced Wireless Lighting should be limited to three for one group.
• Use the provided Speedlight Stand AS-19 for stable placement of the remote flash units.
• Be sure to perform test firing after setting up all flash units (p. 20).
Be sure to direct the light sensor window of
the remote flash unit toward the master flash.
