3 Setting the FlashK
You can set the flash-sync speed for
flash photography in the aperture-priority
AE (f) mode.
N: Auto
The flash sync speed is set automatically within a range of 1/200
sec. to 30 sec. to suit the scene’s brightness. High-speed sync is
also possible.
V: 1/200-1/60 sec. auto
Prevents a slow shutter speed from being set in low-light conditions.
It is effective for preventing subject blur and camera shake.
However, while the subject will be properly exposed with the flash,
the background may come out dark.
W: 1/200 sec. (fixed)
The flash-sync speed is fixed at 1/200 sec. This more effectively
prevents subject blur and camera shake than with [1/200-1/60sec.
auto]. However, in low light, the subject’s background will come out
darker than with [1/200-1/60sec. auto].
[Flash sync. speed in Av mode]
If [1/200-1/60sec. auto] or [1/200 sec. (fixed)] is set, high-speed sync is not
possible in the <f> mode with the external Speedlite.
