ZUsing FV lock with Nikon Speedlights
FV lock is also available with SB-800, SB-600, and SB-
R200 Speedlights (available separately). In this case, set
the Speedlight to TTL mode (the SB-800 can also be used
in AA mode; see the Speedlight manual for details). While
FV lock is in effect, flash output will automatically be
adjusted for changes in Speedlight zoom head position.
When the [COMMANDER MODE d] is set for the [BUILT-
IN FLASH] (➝p.159) under [ FLASH/BKT] in the [SET
UP] menu, 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.
ZUsing FV Lock with the built-in flash
When the built-in flash is used alone, FV lock is only
available If the [TTL d: TTL MODE] is set for the [BUILT-
IN FLASH] (➝p.159) under [ FLASH/BKT] in the [SET
UP] menu.
