Nikon D2H manual 108, FV Lock

Taking Photographs—Flash Photography

FV Lock

This feature is used to lock flash output, allowing photographs to be re- composed without changing the flash level. This ensures 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 sensitivity (ISO equivalency), aperture, and Speedlight zoom head position. FV Lock is available with i-TTL and auto aperture flash 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 flash 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 preflash to determine the appropriate flash level. Flash output will be locked at this

level and FV Lock icons ( and ) will appear in the control panel and viewfinder.

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.

7 Press the FUNC. button to release FV Lock and confirm that the FV Lock icons ( and ) are no longer displayed in the control panel and viewfinder.
