Remote Release from a Slave Unit

In radio transmission wireless shooting, you can perform remote release (remote control shooting) from a 600EX-RT set as a slave unit. When shooting with this function, the “Release Cable SR-N3” (sold separately) may be needed, depending on your camera.

Cameras Compatible with Slave Unit Remote Release

For EOS digital cameras released since 2012, such as the EOS-1D X, the “Release Cable SR-N3” is not needed.

Cameras Not Compatible with SlaveUnit Remote Release

For EOS cameras other than the above that are compatible with E-TTL II/E-TTL autoflash and have an N3 type remote control terminal, the “Release Cable SR- N3” (sold separately) is needed to perform remote release from a slave unit.

As shown in the illustration, use the cable to connect the camera and the 600EX-RT set as the master unit.
