The wireless flash trigger is compatible with all flashes with STANDARD HOT SHOE, such as Canon 580EX II, 580EX, 540EZ, 520EZ, 430EX II, 430EX, 430EZ, 420EX, 420EZ, 380EX, SB-900, SB-800, SB-600, SB-28, SB-27, SB-26, SB-25, SB-24, SB-700, etc
Since the flash trigger kit does not transmit TTL settings, use of a flash or light unit with full manual control is recommended.
