The Nikon Creative Lighting System (CLS)

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

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

1 If a color filter is attached to the SB-900 when v or N (flash) is selected for
white balance, the camera will automatically detect the filter and adjust white
balance appropriately.
2 Controlled remotely with built-in flash in commander mode or using optional
SB-900 or SB-800 flash unit or SU-800 wireless Speedlight commander.
3 m/ft., 20 °C (68 °F), SB-900, SB-800, and SB-600 at 35 mm zoom head position;
SB-900 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-900, SB-800, SB-600, or SB-R200 flash units. 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. 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
n
(approximately 1.4).
