' Radio Transmission Wireless Flash Shooting
Shooting with a Different Flash Mode set for Each Group (p.65)
Wireless shooting using radio transmission has advantages over wireless
shooting using optical transmission, such as being less affected by
obstacles, and not having to point the slave unit’s wireless sensor toward
the master unit. The main functional differences are as follows.
*1, *2 and *3: Some restrictions apply depending on the camera that you use.
