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-N5 has a Guide Number of 8.5 m or 27.9 ft (35 mm zoom
head position); its range at an aperture of f/5.6 is 8.5÷5.6 or
about 1.5 meters (or in feet, 27.9÷5.6=approximately 5 ft).
For each twofold increase in ISO sensitivity, multiply the
Guide Number by the square root of two (approximately
1.4).
