Wireless Multiple Flash Shooting
You can divide the slave units into two or three groups and perform E-TTL II/E-TTL autoflash
while changing the flash ratio (factor). In addition, you can set and shoot with a different flash
mode for each firing group, for up to 5 groups.
● Auto Shooting with Two Slave Groups
