Nikon’s advanced Creative Lighting System (CLS) offers improved communication 
between the camera and compatible flash units for improved flash photography.

❚❚CLS-Compatible Flash Units

The camera can be used with the following CLS-compatible flash units:
• The SB-900, SB-800, SB-700, SB-600, SB-400, and SB-R200:

• The SU-800 wireless speedlight commander: When mounted on a CLS-compatible 

camera, the SU-800 can be used as a commander for remote 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.

1 If a color filter is attached to the SB-900 when AUTO or 

N (flash) is selected for white balance, the 

camera will automatically detect the filter and adjust white balance appropriately.

SB-700 with standard illumination.

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. (35 mm 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).
