TTL multiple flash operation using the Wireless Slave Flash Controller SU-4 (optional)

•TTL multiple flash operation is possible by using the camera’s built-in Speedlight or a Speedlight mounted on the camera’s hot shoe as the master flash unit, and one or more Speedlights mounted on the Wireless Slave Flash Controller SU-4s as slave flash units. The SU-4’s built-in light sensor not only detects when the master flash unit fires to trigger the slave flash unit, but also controls the flash duration of the slave flash unit in sync with the master flash unit.

•Manual multiple flash operation is also possible by setting the flash mode selector to manual (M).

•These Nikon Speedlights are usable:

•SB-29, SB-28/28DX, SB-27, SB-26, SB-25, SB-24, SB-23, SB-22s, SB-22, SB-20, SB-18, SB-16B, SB-15

•For more information, refer to the instruction manual provided with the SU-4.
