17: Illumination (All Modes)

If Off (the default option) is selected, the control panel backlight (LCD illuminator) will turn on only when the power switch is rotated to. If On is selected, the backlight will remain on while the exposure meters are active (note that this will increase the drain on the battery).

Using FV Lock with Optional Speedlights

FV lock is also available with SB-800, SB-600, and SB-R200 Speedlights (available separately). Set the Speedlight to TTL mode (the SB-800 can also be used in AA and A modes; see the Speedlight manual for details). While FV lock is in effect, flash output will automatically be adjusted for changes in Speed- light zoom head position.

When Commander mode is selected for Custom Setting 22 (Built-in flash; 96), FV lock can be used with remote SB-800, SB-600, or SB-R200 flash units if (a) any of the built-in flash, flash group A, or flash group B is in TTL mode, or (b) a flash group is composed entirely of SB-800 Speedlights in TTL or AA mode.

Using FV Lock with the Built-in Flash

When the built-in flash is used alone, FV lock is only available if TTL (the default setting) is selected for Custom Setting 22 (Built-in flash;95).
