Wireless functions
Wireless (multiple) flash shooting is
possible with radio or optical
transmission. For details on wireless
flash, refer to the instruction manual of a
Speedlite compatible with the wireless
flash shooting.
Flash zoom (Flash coverage)
With Speedlites having a zooming flash
head, you can set the flash coverage.
Normally, set this to [AUTO] so that the
camera will automatically set the flash
coverage to match the lens focal length.
Shutter synchronization
Normally, set this to [First-curtain
synchronization] so that the flash fires
immediately after the exposure starts.
If [Second-curtain synchronization] is set, the flash will fire right
before the shutter closes. When this is combined with a slow shutter
speed, you can create a trail of light such as from car headlights at
night. With second-curtain synchronization, two flashes will be fired:
once when you press the shutter button completely, and once
immediately before the exposure ends.
If [High-speed synchronization] is set, the flash can be used at all
shutter speeds. This is especially effective for portraits using fill flash
when you want to give priority to the aperture setting.
