a : 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, perform the same
procedure as “Autoflash Shooting Using
One Slave Unit” (p.55). Set the firing
group to A, B, or C (p.59). The flash will
not fire if it is set to D or E.
When the number of slave units is increased or master flash firing is set
to ON, automatic control is performed to fire all flashes at the same
flash output and to ensure that the total flash output results in the
standard exposure.
Autoflash Shooting Using Multiple Slave Units
If any of the master unit or slave unit (firing group) is not fully charged,
<
G > will be displayed on the master unit’s LCD panel. Make sure
to take the picture after checking the < G > icon is not displayed.
If the < D > lamp is red, radio transmission has not been established.
Check the transmission channels and wireless radio IDs of the master
unit and slave unit again. If you cannot connect with the same settings,
turn the master unit and slave unit off and on again.
The master/slave flash coverage is set to 24 mm. You can also set the
flash coverage manually.
To also fire the master unit, set the master flash firing to ON in step 5 (p.53).
You can press the depth-of-field preview button on the camera to fire the
modeling flash (p.36).
When a Speedlite is set as the master unit, the time until auto power off
takes effect is approx. 5 min.
If a slave unit’s auto power off takes effect, press the master unit’s test
flash button (p.56) to turn on the slave unit. Note that the test flash
cannot be performed while the camera’s timer is operating.
