: Fully Automatic Wireless Flash Shooting
When you need more flash output or you
want to perform lighting more easily, you
can increase the number of slave units
and fire them as a single flash.
To add slave units, use the same
procedure as “Autoflash Shooting Using
One Slave Unit”. Set A, B or C as the
firing group. The flash will not fire if it is
set to D or E.
When the number of slave units is
increased, automatic control is
performed to fire all flashes at the same
flash output and ensure that the total
flash output results in the standard
exposure.
Autoflash Shooting Using Multiple Slave Units
You can press the depth-of-field preview button on the camera to fire the
modeling flash (p.41).
If the slave unit’s auto power off takes effect, press the master unit’s test
flash button (p.13) to turn on the slave unit. Note that the test flash cannot
be fired while the camera’s metering timer is operating.
The autoflash system (E-TTL II/E-TTL) depends on the camera used and
is set automatically. Note that <
a
> is displayed on the LCD panel for
both systems.
You can enable a beep to sound when the charge of all the slave units is
complete (C.Fn-20/p.57).
