Up to 5 groups (A/B/C/D/E)

Sender units are set to Group A
Max. units for communication Up to 16 senders and receivers, combined
Max. sender units

Up to 15

Secondary and additional units serve as sub-senders
Max. receiver units Up to 15

1: Without any obstructions between senders and receivers, and without radio interference from other devices

2: Transmission range may be shorter depending on factors such as how units are arranged, the surrounding environment, and weather conditions
Linked functions

Supports linked shooting with automatic shutter release of up to 16 cameras (sender: 1; receivers: 15) linked to shutter release on the sender camera

Shooting is not simultaneous, because receiver cameras shoot slightly after the sender camera shutter release timing

Using a new, fully charged Battery Pack LP-EL

Based on Canon testing standards
Radio transmission wireless shooting time

Approx. 17 hr. continuously

Time until the Speedlite turns off while connected wirelessly via radio transmission

With sender flash firing disabled, and using a new, fully charged Battery Pack LP-EL
Auto power off

Time from when a connected camera turns off or auto power off is activated until the Speedlite turns off

Since the Speedlite can detect the state of the connection with the camera, while the camera is on, it does not enter auto power off alone (unintentionally).
