3. Multi-Speedlite, Wireless lighting configurations You can create two or three slave groups to make shooting effect better meet your requirements, and set flash ratio for TTL autoflash shooting of master, as well as manual flash output, frequency flash etc. (1). Wireless flash of two slave units made up by YN568EX z Wireless option setting: Sc/Sn for operation z Communication Channel setting: 1, 2, 3, 4 z Groups setting: Set one YN568EX as group A, and set the other one as group B.
Press the test button of master to test whether the flash works normally; if the flash does not fire, adjust the slave unit’s angle toward the master unit and distance from the master unit. NOTE: If ratio is set, the slave unit in group C will not fire. If you have the slave group set to for three slave units, all three slave units will be controlled as if they were one speedlite in slave group A. 4.
5. Shooting Examples with Wireless Flash System z z z z z z z Master unit: 580-II, SB-900/800/700, 7D/60D/600D with built-in commander mode, Nikon c-commander and ST-E2. Slave unit: YONGNUO EX series flash, you can create three slave groups at all. Use the mini flash stand (tripod socket provided) to prop up the YN568EX speedlite. Swing the YN568EX so that its wireless sensor faces the master unit.

Vignetting appears in photos or only part of the subject is illuminated? Please check the current coverage of focal length and make sure if the lens focal length exceeds the coverage range of the flash. The product’s zooming range is 24~105mm of the medium format system.
