• 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

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 with the SB-400.

A
Guide Number
To calculate the range of the flash at full power, divide the Guide 
Number by the aperture. For example, at ISO 100 the SB-800 has a Guide 
Number of 38 m or 125 ft (35mm zoom head position); its range at an 
aperture of f/5.6 is 38÷5.6 or about 6.8 meters (or in feet, 
125÷5.6=approximately 23 ft 7 in.). For each twofold increase in ISO 
sensitivity, multiply the Guide Number by the square root of two 
(approximately 1.4).
