~ Using FV lock with the Built-in Flash
FV lock is only available with the built-in flash when TTL (the default
option) is selected for Custom Setting e3 (Flash cntrl for built-in flash,
pg.309).
PI Using FV Lock with Optional Flash Units
FV lock is also available with 5B-900, 5B-800, 5B-600, 5B-400, and 5B-R200
flash units (available separately). Set
the optional flash to TTL mode (the
5B-900 and 5B-800 can also be used in AA mode;
see the flash manual for
details). While FV lock is in effect, flash output will automatically be
adjusted for changes in flash zoom head position.
When Commander
mode is selected for Custom Setting e3 (Flash cntrl
for built-in flash,
pg. 309), FV lock can be used with remote 5B-900,
5B-800, 5B-600,
or 5B-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 5B-900 and 5B-800 flash units in TIL or AA mode.
