Flash Photography
• Auto FP High-Speed Sync
Auto FP High-Speed Sync is activated automatically at shutter speeds faster
than 1/250 sec., allowing auto flash control at all shutter speeds up to and
including 1/8,000 sec. As a result, the flash can be used without concern for
maximum sync speed, even in daylight shots taken at maximum aperture.
To use Auto FP High-Speed Sync, choose “1/250 (FP auto)” for Custom Setting “e1:
Flash sync speed” (x 104). Auto FP High-Speed Sync supports Advanced Wireless
Lighting. With a single Speedlight, i-TTL flash control, Auto Aperture flash, Distance-
Priority manual, and manual flash mode are available. In multiple flash, you can
choose from i-TTL flash control, Auto Aperture flash, Non-TTL Auto flash, and manual
flash mode.
• AF-Assist for Multi-Area AF
The SB-800/SB-600 features AF-assist illuminator linked to the F6 focus
areas, allowing autofocus to be used even at night, regardless of the
subject’s position in the frame.
AF-assist illuminator can be used in all AF Area modes, including Single Area AF,
Dynamic AF, Group Dynamic AF, and Dynamic AF with Closest-Subject Priority. If the
subject is poorly lit, the AF-assist illuminator will light automatically when Single
Servo AF is used in combination with a 24-105mm AF Nikkor lens (if a lens wider
than 35mm is used, the illuminator may not light if the focus area at the left or right
edge of the frame are selected).
