Fv Lock - Nikon D7500 User Manual

FV Lock

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.
