refer to the Speedlite’s instruction manual.
Flash mode
With an external Speedlite, you can select the flash mode to suit
your flash shooting.
[E-TTL II] is the standard mode for
EX-series Speedlites for automatic
flash shooting.
[Manual flash] enables you to set the
flash output yourself. This is for
advanced users.
Regarding other flash modes, refer to
your Speedlite’s instruction manual.
Shutter sync.
Normally, set this to [1st curtain] so that the flash fires immediately
after the exposure starts.
If [2nd curtain] is set, the flash will fire right before the exposure
ends. When this is combined with a slow sync speed, you can create
a trail of light such as from car headlights at night. With 2nd curtain
sync, two flashes will be fired, once when you press the shutter
button completely, and once immediately before the exposure ends.
If an external Speedlite is attached, you can also set [Hi-speed]. For
details, see the Speedlite’s instruction manual.
