Use Only Nikon Flash Accessories
Use only Nikon flash units. Negative voltages or voltages over 250 V applied to the accessory
shoe could not only prevent normal operation, but damage the sync circuitry of the camera or
flash. Before using a Nikon flash unit not listed in this section, contact a Nikon-authorized
service representative for more information.
• 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 5B-800 has a Guide Number of 38 m or 125 ft. (35 mm zoom head
position); its range at an aperture off/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).
