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.
