3 sec. Blinks for approx. 3 sec. Beeps for approx. 3 sec. Both the master and remote flash units have fired at full output and light may have been insufficient for correct exposure. Use a wider aperture and reshoot. Lights up or does not come on (not blinking) Blinks for approx. 3 sec. Beeps for approx. 3 sec. The remote flash unit has fired at full output and light may have been insufficient for correct exposure. The light sensor could not detect when to stop firing in sync with the master flash unit, because a strong reflection from the remote flash unit itself or light from another remote flash unit may have entered the light sensor window. Change the direction or position of the remote flash unit and reshoot. Advanced 89 Multiple flash shooting using cords The SB-800 can be used with Speedlights compatible with the TTL auto flash mode to perform multiple flash shooting using cords. • Use of the SB-50DX and SB-23 as remote flash units is not recommended, because the standby function cannot be canceled. • Speedlights SB-11, SB-14, SB-140, and SB-21B cannot be used with the F-401/N4004 or F-401s/N4004s as either master or remote flash units. • There is no limitation in usable cameras. •With digital SLRs and COOLPIX cameras compatible with i-TTL, only manual flash operation is possible. ¦ ¦¦ The maximum number of flash units to be connected using cords • Up to five units including the master flash unit can be used for multiple flash photography at a total cable length of 10m (33 ft.). • Make sure the combined total of the coefficients in the table below for all flash units used together does not exceed 20 at 20°C (68°F) or 13 at 40°C (104°F). • If it exceeds these figures, you may not be able to take a second shot after the first one. In this case, turn off the power of all flash units and reduce the total number of flash units connected. Speedlight Coefficient SB-800, SB-80DX, SB-50DX, SB-30, SB-29, SB-29s, SB-28, SB-28DX, SB-27, SB-26, SB-25, SB-24, SB-22s, SB-14, SB-11, SB-140 1 SB-23, SB-21, SB-17, SB-16, SB-15 4 SB-22 6 SB-20 9 ¦¦¦ Notes on multiple flash shooting using cords • Be sure to see the instruction manuals of your cameras, Speedlights, and accessories. • Refer to “System chart for TTL multiple flash shooting using cords” (p. 94) and your cameras and Speedlights instruction manuals for proper connection. • Use the optional TTL Multi-Flash Sync Cords SC-27, SC-26, SC-19 or SC-18 to connect the SB-800 to more than one remote flash unit. • Use the optional Multi-Flash Adapter AS-10, if the remote flash units are not equipped with multiple flash terminals. • Use the optional Multi-Flash Adapter AS-10 to attach the remote flash unit(s) to a tripod. • Be sure to cancel the master flash unit’s Monitor Preflashes. • Multiple flash shooting using cords can be performed in two modes: (1) TTL multiple flash; and (2) Manual multiple flash. Performing multiple flash shooting in the Manual mode, however, is not recommended, since it is difficult to obtain the correct exposure. Use the TTL auto flash mode with cameras compatible with TTL auto flash. •To ensure proper exposure, make test shots before shooting important events. Advanced 91 Multiple flash shooting using cords ¦ ¦¦ TTL multiple flash (not possible with digital SLRs and COOLPIX cameras compatible with i-TTL) FLASH READY 1 Set the camera’s exposure mode to Aperture- Priority Auto (A) or Manual (M). 2 Attach the master flash unit to the camera, turn the power on, and set the flash mode to TTL auto flash. •A flash mode, in which Monitor preflashes are fired, cannot be used. 3 When using either the optional TTL Multi-Flash Sync Cord SC-27,SC-26, SC-19 or SC-18, turn off all flash units before connecting the master flash unit to the remote flash units. 4 Turn on all remote flash units and set the flash mode on all remote flash unit to TTL auto flash. 5 Confirm the aperture and flash shooting distance as in normal TTL auto flash shooting, then shoot. • See page 17 concerning the TTL auto flash mode. • When the flash has fired at its maximum output and underexposure may have occurred, the ready-light on the SB-800 blinks for approx. 3 sec. To compensate, use a wider aperture or move closer to the subject and reshoot. 93 ¦¦¦ Manual multiple flash 1 Set the camera’s exposure mode to Aperture- Priority Auto (A) or Manual (M). 2 Turn off the power and attach the master flash unit to the camera. 3 Connect the sync terminal on the master flash unit to the remote flash unit using the optional Sync Cord SC-11 or SC-15. 4 Turn on the power of all flash units and set the flash mode on all units to Manual flash. • The flash output level can be adjusted on the SB-800, SB-80DX, SB-28, and so forth, if necessary (p. 43). • Repeating flash is not possible. 5 Confirm the aperture and flash shooting distance as in normal Manual flash shooting, then shoot. • See page 46 for more information about the Manual flash mode.
