i-TTL Flash Control
In i-TTL flash control, the camera adjusts the flash level based on
reflections from a series of nearly invisible pre-flashes (monitor pre-
flashes) emitted by the flash unit immediately before firing. There are
two types of i-TTL flash control:
i-TTL balanced fill-flash
, in which flash
output is adjusted for a natural balance between the main subject and
ambient background lighting, and
standard i-TTL flash
, in which flash
output is adjusted to bright lighting in the frame to a standard level
without taking the brightness of the background into account. To use
i-TTL flash control with optional flash units other than the SB-400, select
i-TTL flash control mode on the flash unit before shooting. When using
an SB-700 or SB-400, note that i-TTL balanced fill-flash is activated
automatically when matrix or center-weighted metering is selected with
the camera, while standard i-TTL is used with spot metering.

Optional Flash Units
Optional flash units enter standby when the camera is turned off; check
the flash-ready indicator on the flash unit before shooting. Auto power
zoom is supported with SB-910, SB-900, SB-800, SB-700, and SB-600
flash units, but note that a wide panel may be required to eliminate
vignetting at ranges under 2 m (6 ft 7 in.). Advanced Wireless Lighting,
auto FP high-speed sync, and AF-assist for multi-area AF are not
supported.
