Nikon D700 - Fvlock

FVLock
This feature is used to lock flash output, allowing photographs to
be recomposed without changing the flash level and ensuring that
flash
output is appropriate to the subject even when the subject is
not positioned in the center of the frame. Flash output is adjusted
automatically for any changes in
ISO sensitivity and aperture.
