*1: If the Speedlite does not have a transmission channel setting function, the camera can work with any channel.

*2: In small rooms, the slave unit may work even if its wireless sensor does not face the camera. The camera’s wireless signals can bounce off the walls and be received by the slave unit. When using an EX-series Speedlite with fixed flash head and wireless sensor, take pictures to make sure it can fire.

The camera’s master unit function cannot be used for wireless flash shooting with radio transmission.
