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).
