Accessories for Multiple Flash Operation To perform TTL multiple flash operation, use the following optional accessories. Wireless Slave Flash Controller SU-4 • The SU-4 enables a Speedlight other than the SB-80DX, 50DX and 30 to be used as a slave flash unit to perform wireless multiple flash operation (p. 48). Bracket SK-7 • The SK-7 is used to position the camera and SB-50DX horizontally for multiple flash operation. • Use the TTL Multi-Flash Adapter AS-10 to attach the SB-50DX on the Bracket SK-7. TTL Remote Cord SC-17 (approx. 1.5m/4.9 ft.)/SC-24 (approx. 1.5m/4.9 ft.) • Use the SC-17/SC-24 for off-camera TTL auto flash operation or TTL multiple flash operation with the SB-50DX. Two TTL multiple flash terminals and one tripod socket are provided. For F5 cameras with the DW-30/DW-31 finder or for F4 cameras with the DW-20/DW-21 finder, use the SC-24. TTL Multi-Flash Sync Cord SC-18 (approx. 1.5m/4.9 ft.)/SC-19 (approx. 3m/9.8 ft.) • Use the SC-18 or SC-19 cord to connect the Speedlights via the TTL multiple flash terminal (on the AS-10, SC-17, etc.) for TTL multiple flash operation. TTL Multi-Flash Adapter AS-10 • The TTL Multi-Flash Adapter AS-10 can be connected to perform TTL multiple flash operation using cords for slave flash Speedlight units that do not have TTL multiple flash terminals. However, in TTL multiple flash operation using cords, use of the SB-50DX (or SB-23) as a slave flash unit is not recommended (p. 55). The tripod socket of the AS-10 enables stable placement of the Speedlight unit on a tripod or Bracket SK-7 in wireless multiple flash operation. • Three multiple flash terminals are provided on the AS-10. 56 EFFECTIVE SPEEDLIGHT PLACEMENT Properly adjusting the position and angle of the Speedlights improves results in multiple flash photography. 57
