When a flash unit that supports unified
flash control (an SB-5000, SB-500,
SB-400, or SB-300) is mounted on the
camera, the flash control mode, flash
level, and other flash settings can be
adjusted using the [
Flash control ] >
[ Flash control mode ] item in the photo shooting menu (in the
case of the SB-5000, these settings can also be adjusted using
the controls on the flash unit). The options available vary with
the flash used, while the options displayed under [
Flash control
mode ] vary with the mode selected. Settings for other flash
units can only be adjusted using flash unit controls.
• [ TTL ]: i-TTL mode. In the cases of the SB-500, SB-400, and

automatically according to the amount of light reflected by
