NOTES ON FLASH PHOTOGRAPHY
•Use only Nikon Speedlights. Other units may damage the
camera’s electrical circuits due to incompatible voltage
requirements*, electric contact alignment or switch phase.
* Not compatible with 250V or higher.
•When using a special Speedlight, such as a studio strobe
system, with a time-lag provision or one with a long flash dura-
tion (i.e., Medical-Nikkor 120mm f/4*), adjust the shutter
speed down to 1/125 sec. or slower.
* Medical-Nikkor 120mm f/4 is not available in EU countries.
•SB-26 can be used for multiple flash photography in its wire-
less mode. See Speedlight instruction manual for details.
•When the center focus area is not selected, AF-assist illumina-
tor does not light.
•For multiple flash photography with the F5, if the electric
current in the synchro circuit exceeds a certain level, you may
not be able to take a second shot. Take care that the
combined total of the coefficient (numbers shown in parenthe-
ses 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).
SB-50DX (1) SB-29 (1) SB-28/28DX (1) SB-27 (1)
SB-26 (1) SB-25 (1) SB-24 (1) SB-23 (4)
SB-22s (1) SB-22 (6) SB-21 (4) SB-20 (9)
SB-19 (2) SB-18 (16) SB-17 (4) SB-16 (4)
SB-15 (4) SB-14 (1) SB-12 (1) SB-11 (1)
If you are unable to take a second shot, disconnect the master
Speedlight from the camera, or turn each of the Speedlights
off and on. This resets the circuits so you can resume shoot-
ing.
This also applies when using any non-Nikon studio Speedlight
system.
