Accessory Shoe ®
Located at the base of the rewind knob @, the accessory shoe allows direct mounting of a Nikon dedicated flash unit, such as the 88-12, 88-16A or 88-17. To mount other direct-mounting flash units (having either an 180- or Nikon F2-type mounting foot) to the F3AF'saccessory shoe, a Nikon Flash Unit Coupler is required (for details, refer to page 56.) The accessory shoe also accepts accessory cords, such as the 8C-12 and 8C-13, for convenient flash photography with Nikon bracket-mounting units, such as the 88-11 and 14.
Three electrical contacts @ on the accessory shoe provide for synchronization of the flash unit, automatic TTL output control, and ready-light indication (via an LED) in the camera's view- finder, plus auto switching to the proper synchronization speed
of 1/80sec.
Caution: For flash photography, it is recommended that you use a Nikon dedicated electronic flash unit which operates with a low-voltage curren t. The use of any other flash which operates at high voltages may damage the camera's circuitry; any damage caused by such use is not covered by the Nikon warranty.
