1 If a color filter is attached to the SB-910, SB-900, or SB-700 when v or N (flash) is selected for white
balance, the camera will automatically detect the filter and adjust white balance appropriately.
2 Wireless flash control is not available.
3 Controlled remotely with built-in flash in commander mode or using optional SB-910, SB-900,
SB-800, or SB-700 flash unit or SU-800 wireless Speedlight commander.
4 m/ft, 20 °C (68 °F), SB-910, SB-900, SB-800, SB-700, and SB-600 at 35 mm zoom head position; SB-910,
SB-900, and SB-700 with standard illumination.
• SU-800 Wireless Speedlight Commander: When mounted on a CLS-compatible camera,
the SU-800 can be used as a commander for remote SB-910, SB-900, SB-800,
SB-700, SB-600, or SB-R200 flash units in up to three groups. The SU-800 itself is
not equipped with a flash.
A
Guide Number
To calculate the range of the flash at full power, divide the Guide Number by the aperture. If,
for example, the flash unit has a Guide Number of 34 m or 111 ft (ISO 100, 20 °C/68 °F); its
range at an aperture of f/5.6 is 34÷5.6 or about 6.1 meters (or in feet, 111÷5.6=approximately
19 ft 10 in.). For each twofold increase in ISO sensitivity, multiply the Guide Number by the
square root of two (approximately 1.4).
