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.
Refer to the documentation provided with the flash unit for details.
❚❚ CLS-Compatible Flash Units
The camera can be used with the following CLS-compatible flash units:
• The SB-910, SB-900, SB-800, SB-700, SB-600, SB-400, and SB-R200:
• 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.

SB-900, and SB-700 with standard illumination.
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).
