Nikon instruction manual Setting the SB-800 to SU-4 type wireless multiple flash

SU-4 type wireless multiple flash shooting

SU-4 type wireless multiple flash can be performed in two ways: (1) In the A (auto) mode, in which the wireless remote flash units start and stop firing in sync with the master Speedlight, and (2) in the M (manual) mode, in which the wireless remote flash units only start firing in sync with the master Speedlight.

•Speedlights featuring wireless multiple flash capability can be used either as the master or remote flash unit.

•Speedlights compatible with TTL auto flash can be used as the master flash unit. The optional Wireless Slave Flash Controller SU-4 is necessary when you want to use these Speedlights as remote flash units.

•The camera’s built-in Speedlight can also be used as a master flash unit.

•There is no limitation in usable cameras.

■■■ Setting the SB-800 to SU-4 type wireless multiple flash

To perform SU-4 type wireless multiple flash, set the wireless flash mode to “SU-4” using Custom settings (p. 67).

Master flash and remote flash units

•First, set the SB-800’s wireless multiple flash mode to “SU-4” using the Custom settings, then attach the SB-800 to the camera. The indicator O appears on the LCD panel telling you that the SB-800 is set as a master flash unit. If you detach the SB-800 from the camera, the indicator automatically changes to P signifying that the SB-800 is set as a remote flash unit.

Notes on the master flash unit

•When the SB-800 is set as the master flash unit, Monitor Preflashes are canceled. For other Speedlights, be sure to cancel the master flash unit’s Monitor Preflashes.

•The following flash modes are recommended for the master flash unit.
