Flash sync speed lets you select a basic synchronization speed
from 1/60s to 1/250S. The D300(S) has a more flexible Flash
sync speed than many cameras.
Or, if you prefer, you can use the two Auto FP modes of your
camera—1/250 s (Auto FP) or 1/320 s (Auto FP). These Auto
FP modes are available only with certain external Speedlights
and not with the built-in pop-up Speedlight.
At the time of writing this book, the four Nikon Speedlights
that can be used with the D300(S) in Auto FP high-speed
sync mode are as follows:
▪ SB-900
▪ SB-800
▪ SB-600
▪ SB-R200
Auto FP high-speed sync enables the use of fill-flash even in
bright daylight with wide aperture settings. It allows you to
set your camera to the highest shutter speed available, up to
1/8000s, and still use the external flash unit to fill in shadows.
Here are your choices (see Figure 4-48):
▪ 1/320 s (Auto FP)
▪ 1/250 s (Auto FP)
▪ 1/250 s
▪ 1/200 s
▪ 1/160 s
▪ 1/125 s
