1 Only available when SU-800 is used to control other flash units.
2 CPU  lens  required.
3 Standard i-TTL flash for digital SLR is used with spot metering or when selected with flash unit.
4 Standard i-TTL flash for digital SLR is used with spot metering.
5 Selected with flash unit.
6 Auto  aperture  (AA) is used regardless of mode selected with flash unit.
7 Can  be  selected  with  camera.

A

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).
