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.
❚❚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, SB-300, 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.

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.
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).
