Taking Photographs—Flash Photography
FV Lock
This feature is used to lock fl ash output, allowing photographs to be re-
composed 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 sensitivity (ISO equivalency), aperture, and Speedlight zoom head position.
FV Lock is available with i-TTL and auto aperture fl ash control, Advanced
Wireless Lighting, and Auto FP High-Speed Sync.
To use FV Lock:
1
Select FV Lock or FV Lock/Lens data for Custom Setting f4 (FUNC. but-
ton; 201).
2
Mount an SB-800 Speedlight on the camera accessory shoe.
3
Turn the SB-800 on and set the fl ash mode to TTL or AA (see the SB-800
instruction manual for details).
4
Position the subject in the center of the frame
and press the shutter-release button halfway
to focus.
5
Press the FUNC. button. The SB-800 will emit a
monitor prefl ash to determine the appropriate
fl ash level. Flash output will be locked at this
level and FV Lock icons ( and ) will
appear in the control panel and viewfi nder.
6
Recompose the photograph and press the
shutter-release button the rest of the way
down to shoot. If desired, additional pictures
can be taken without releasing FV Lock.
