Use Only Nikon Flash Accessories

Use only Nikon Speedlights. Negative voltages or voltages over 250V 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 Speedlight not listed in this section, contact a Nikon-authorized service representative for more information.

The AS-15 Accessory Shoe Adapter

When the AS-15 accessory shoe adapter (available separately) is mounted on the camera accessory shoe, flash accessories can be connected via a sync cable.
