Multiple Flash Photography
Photography, especially when using the SB-26 as a master flash unit with
other slave flash unit(s). The Sensor system is designed to analyze Monitor
Preflash reflection from a single SB-26 (ideally, mounted on the camera) and to
control light output from that particular unit, but not from the other slave(s).
• Use optional Multi-Flash Sync Cord SC-18 (1.5m) and/or
SC-19 (3m) to connect flash units via the SB-26’s TTL
multiple flash terminal. Remove the rubber cover to use.
• Use optional TTL Remote Cord SC-17 or SC-24* for use
with the SB-27, SB-23, SB-22, SB-21B, SB-20 and/or
SB-15 as a master flash unit.
* Used for F5 with the DW-30/DW-31 attached or for F4-series with the DW-20/
DW-21 attached.
• Use optional TTL Multi-Flash Adapter AS-10 for use with
the SB-27, SB-22, SB-21B, SB-20 and or SB-15 as a
slave flash unit.
• Use optional TTL Remote Cord SC-23 for use with the
SB-140, SB-14 and/or SB-11.
• The SB-11/14/140 (even with SC-23) or SB-21B cannot be
used for TTL multiple flash photography with the F-401/
N4004 and F-401s/N4004s.
• Use the ON position to activate a slave flash unit; the
STBY does not function (SB-26, SB-25, SB-24, SB-22 and
SB-20).
The SB-23 offers only OFF and TTL/STBY positions for
power switching. This means it cannot be used as a slave.
• Select Forced TTL mode when using SB-27 as a slave
flash unit.
Manual Multiple Flash Photography
• Use the sync/multiple flash terminal for connection with
other Speedlights via optional sync cords.
• Use optional Sync Cord SC-11 or SC-15.
• Set and use Manual
i
Flash mode on each Speedlight
for correct exposure.
TTL Multiple Flash Photography
• Use the TTL multiple flash terminal for connecting other
Speedlights via optional sync cords.
• You can use one Speedlight for the master flash unit and
up to four other units for slaves.
See the chart on pages 134 to 135 to confirm available
Speedlights for master and slave use.
• Note the following when using an F90-Series/N90 camera
for TTL Auto Flash operation with multiple Speedlights:
a. Use the SB-26 as a slave flash unit whenever possi-
ble, or
b. When using the SB-26 as master, avoid Monitor
Preflashes* by (1) performing Standard TTL Flash, (2)
upward tilting or rotating the flash head (the distance
indicator bars
/
disappear), or (3) using a lens
other than AF Nikkor (including D-type) or AI-P lens-
es to perform Center-Weighted or Spot Fill-Flash.
* Because 3D Multi-Sensor and Multi-Sensor Balanced Fill-Flash take advan-
tage of the SB-26’s Monitor Preflash and the camera’s TTL Multi-Sensor, it is
difficult to manage such fill-flash operations for TTL Multiple Flash
When a second shot cannot be taken (F5, F90X/
N90s, F90-Series/N90, F70-Series/N70, F4-Series,

For multiple flash photography, if the electronic current
in the synchro circuit exceeds a certain level, you may
not be able to take a second shot after taking the first
shot.
Take care that the combined total of the coefficients
(numbers shown in parentheses below) for all
Speedlights used at any one time does not exceed 20
at 20°C (68°F), or 13 at 40°C (104°F).
If you are unable to take a second shot, disconnect
the master Speedlight from the camera, or turn each
of the Speedlights off once. This resets the circuits so
you can resume shooting.
