Autoflash Shooting Using Multiple Slave Units

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.

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).
