3 Setting the FlashK
Flash mode
When using an external Speedlite, you can select the flash mode to
suit your desired flash shooting.
[E-TTL II] is the standard mode of
EX-series Speedlites for automatic
flash shooting.
[Manual flash] is for advanced users
who want to set the [Flash output]
(1/1 to 1/128) themselves.
Regarding other flash modes, refer to
the instruction manual of a Speedlite
compatible with the functions.
Shutter synchronization
Normally, set this to [1st curtain] so that the flash fires immediately
after the exposure starts.
[2nd curtain]
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 a more natural feel.
With E-TTL II (auto flash exposure), two flashes will be fired: once when
you press the shutter button completely, and once immediately before
the exposure ends. Also, if the shutter speed is 1/30 sec. or faster, first-
curtain synchronization will be applied automatically.
If an external Speedlite is attached, you can also select [High-speed
synchronization] (e). For details, refer to the Speedlite’s
instruction manual.
Wireless functions
When performing optical transmission wireless flash shooting using
the master function of the built-in flash, see “Using Wireless Flash”
on page 189. When performing wireless flash shooting with radio or
optical transmission using the master function of the external
Speedlite, refer to the Speedlite’s instruction manual.
Flash exposure compensation
See “Flash Exposure Compensation” on page 178.
