Flash Synchronization Speed in Av Mode
You can set the flash sync speed for flash photography in the aperture-priority AE (f) mode.
: Auto
The flash sync speed is set automatically within a range of 1/250 sec. to 30 sec. to suit the scene’s brightness. High-speed sync is also possible.
: 1/250-1/60 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.
: 1/250 sec. (fixed)
The flash sync speed is fixed at 1/250 sec. This more effectively prevents subject blur and camera shake than with [1/250-1/60sec. auto]. However, in low light, the subject’s background will come out darker than with [1/250-1/60sec. auto].
If [1/250-1/60sec. auto] or [1/250 sec. (fixed)] is set, high-speed sync is not possible in the <f> mode with the external Speedlite.
