Wireless Flash
There are two methods for wireless flash shooting: light-signal flash shooting that uses the light of the flash attached to
the camera as a signal light, and radio-signal flash shooting that uses wireless communication. To perform radio-signal
flash shooting, use a compatible flash or the Wireless Radio Commander (sold separately). For details on how to set
each method, refer to the instruction manual of the flash or the Wireless Radio Commander.
