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: Feature Flash unit SB-910 1 SB-900 1 SB-800 SB-700 1 SB-600 SB-400 2 SB-R200 3 Guide No. 4 ISO 100 ISO 200 34/111 48/157 34/111 48/157 38/125 53/174 28/92 39/128 30/98 42/138 21/69 30/98 10/33 14/46 1 If a color filter is attached to the SB-910, SB-900, or SB-700 when AUTO 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. 3 Controlled remotely using optional SB-910, SB-900, SB-800, or SB-700 flash unit or SU-800 wireless Speedlight commander. 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. • 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-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. A Guide Number To calculate the range of the flash at full power, divide the Guide Number by the aperture. n 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). 173
