Flash value lock (FV lock) The SB-5000 sets the flash output to locked flash exposure. This maintains the subject's illumination, even if the composition changes. • The flash exposure level (brightness) remains the same even when the aperture is changed or lens is zoomed in and out, because the flash output level automatically changes. • Several frames can be shot during FV lock operation. • FV lock also functions in Advanced Wireless Lighting. • The available flash modes are i-TTL, auto aperture flash with monitor pre-flashes and non-TTL auto flash with monitor pre-flashes. • FV stands for flash value, meaning flash illuminated subject exposure. Slow sync The flash is controlled at a low shutter speed to obtain the correct exposure for both the main subject and background in low-light situations. E • Since low shutter speeds are normally used, use of a tripod is recommended to prevent camera shake. Red-eye reduction The SB-5000 fires 3 flashes at low output just before the picture is taken to reduce the red-eye effect caused by the flash light. E-32 Functions

Functions
Flash value lock (FV lock)
The SB-5000 sets the flash output to locked flash exposure. This maintains
the subject’s illumination, even if the composition changes.
The flash exposure level (brightness) remains the same even when the
aperture is changed or lens is zoomed in and out, because the flash
output level automatically changes.
Several frames can be shot during FV lock operation.
FV lock also functions in Advanced Wireless Lighting.
The available flash modes are i-TTL, auto aperture flash with monitor
pre-flashes and non-TTL auto flash with monitor pre-flashes.
FV stands for flash value, meaning flash illuminated subject exposure.
Slow sync
The flash is controlled at a low shutter speed to obtain the correct
exposure for both the main subject and background in low-light
situations.
Since low shutter speeds are normally used, use of a tripod is
recommended to prevent camera shake.
Red-eye reduction
The SB-5000 fires 3 flashes at low output just before the picture is taken to
reduce the red-eye effect caused by the flash light.
