Accessory Shoe And Sync Terminal - Nikon FA Instruction Manual

Accessory Shoe and Sync Terminal
78
The accessory shoe of the FA allows direct mounting of the
Nikon Speedlight SB-15, SB-16B, SB-18, SB-19 or other
electronic flash with an ISO-type mounting foot. Other flash
units may be mounted with a flash unit coupler (see table on
page 61). Four electrica contacts
provide the following: proper synchronization of the flash
unit, automatic flash output stop, identification of a TTL flash
unit, and both ready-light indication in the camera's
viewfinder (via and LED) and autoswitching to the proper
sync speed of 1/250sec. with Nikon dedicated flash units.
To use flashbulbs or an electronic flash unit without a hot-
shoe contact, use the camera's sync terminal. The FA's sync
terminal with a protective screw-in cover, accepts all
standard plug-in PC cords It is also threaded for use with a
Nikon screw-in PC cord.

The FA features an X-sync contact only, allowing electronic flash
units to be synchronized at a speed of 1/250sec or slower To
prevent mistakes, the camera also offers automatic switchover of
the shutter speed for proper synchronization with the SB-15,
SB-16B, SB-18, SB-19, etc., as shown in the table on the next page.
For creative fill-in flash effects, you can set the speed manually to
1/250sec or below and the shutter fires at the speed set with the
speed in use displayed in the viewfinder.
Flashhulbs can also be used at the following shutter speed sync
ranges.

• The use of other manufacturers' flash units, even with the same
ISO-type mounting foot, may cause abnormalities to the IC
circuitry. Units having a high voltage synchro circuit may also
affect shutter speed precision.
• When using a special electronic flash unit that has provision for
time lag, adjust the shutter speed down to 1/125 sec. or slower
according to the time lag.
