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.

 

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.
