Flash Contacts
The D700 is equipped with an accessory shoe for attaching
optional flash units directly to the camera and a sync terminal that
allows flash units to be connected via a sync cable.

❚❚The Accessory Shoe

Use the accessory shoe to mount optional
flash units directly on the camera without a
sync cable (pg. 378).
The accessory shoe is
equipped with a safety lock for Speedlights
with a locking pin, such as the SB-900, SB-800,
SB-600 and SB-400.

❚❚The Sync Terminal

A sync cable can be connected to the sync
terminal as required.
Do not connect
another flash unit via a sync cable when
performing rear-curtain sync flash
photography with a flash unit mounted on
the camera accessory shoe.
DISO Sensitivity
When auto ISO sensitivity control is on (pg. 108), ISO sensitivity will
automatically be adjusted as required for optimal flash output when an
optional SB-900, SB-800, SB-600, or SB-400 flash unit is attached.
This may
result in foreground subjects being underexposed in photographs taken
with the flash at slow shutter speeds, in daylight, or against a bright
background.
In these cases, choose a flash mode other than slow sync or
choose a larger aperture.
