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 5etting e2 (Flash cntrl for built-in flash; pg. 185).
• Using FV Lock with Optional Flash Units
In addition to the built-in flash, FV lock is available with 5B-900, 5B-800, 5B-600, 5B-400 and
5B-R200 flash units (available separately). 5et 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 5etting e2 (Flash cntrl for built-in flash,
pg. 185), 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 58-900 and 5B-800 flash units in TTL or AA mode.
