Using a transmitter and a Speedlite compatible with radio transmission wireless shooting makes it easy to shoot with advanced wireless multiple flash lighting, in the same way as normal E-TTL II/E-TTL autoflash shooting.
The system is designed so that the settings of the transmitter attached to the camera (master) are automatically reflected on the Speedlite that is wirelessly controlled (slave). Therefore, you do not need to operate the slave unit while shooting.
The basic relative positions and operating range are as shown in the figure. You can then perform wireless E-TTL II/E-TTL autoflash shooting just by setting the master unit to <ETTL>.
* Before shooting, perform a test flash (p.10) and test shooting.
* The transmission distance may be shorter depending on the conditions such as the positioning of slave units, the surrounding environment and weather conditions.
Set a flash that is compatible with radio transmission wireless flash shooting as the slave unit. For the slave unit settings, see the flash's instruction manual.

Perform FE lock by operating the camera. For the operations, see the camera and flash's instruction manual.
You can use two or more master units (master units + slave units =maximum of 16 units). By preparing multiple cameras with master units attached, you can shoot by changing cameras while keeping the same lighting (slave units).
Note that when using two or more master units, the color of the <LINK> lamp varies depending on the order in which the power was turned on. The first master (main master) is green and the second and subsequent masters (sub-masters) are orange.
The exposure is controlled automatically so that the total flash output of firing groups results in the standard exposure.
• Operate and set the slave units one by one.

The slave units flash at the set flash ratio.
ETTL: Wireless Multiple Flash Shooting with Flash Ratio ■ Slave Group Control
If you need more flash output or wish to perform more sophisticated lighting, you can increase the number of slave units.
Simply set an additional slave unit to the firing group (A, B or C) whose flash output you want to increase. You can increase the number of slave units up to 15 units in total.
For example, if you set a firing group with three slave units to <A>,the three units are controlled as a single firing group A with a large flash output.
• To fire the three firing groups A, B and C at the same time, set <A:B:C>. With the < A:B > setting, firing group C does not fire.
• If you shoot with firing group C pointing directly toward the main subject, overexposure may result.
• The flash ratio of 8:1 to 1:1 to 1:8 is equivalent to 3:1 to 1:1 to 1:3 (1/2-stop increments) when converted to number of stops.
• The details of the flash ratio settings are as follows.
8:1 . 4:1 . 2:1 . 1:1 . 1:2 . 1:4 . 1:8
5.6:1 2.8:1 1.4:1 1:1.4 1:2.8 1:5.6
