FV Lock
This feature is used to lock fl ash output, allowing photographs to be recomposed
without changing the fl ash level. This ensures that fl ash 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 or aper-
ture. To use FV lock:
1
Select FV Lock or FV Lock/Lens Data for Cus-
tom Setting f4 (FUNC. Button; 170).
2
Press the fl ash pop-up button to raise the fl ash.
3
Position the subject in the center of the frame
and press the shutter-release button halfway to
focus.
4
Press the FUNC. button. The fl ash will emit a
monitor prefl ash to determine the appropriate
fl ash level. Flash output will be locked at this lev-
el and FV lock icons ( and ) will appear
in the control panel and viewfi nder.
5
Recompose the photograph.
