Today I got two Cactus RF60 flashes and a V6 trigger for my A7R. So far everything works excellent, and the system is super easy to set up and use. Controlling the flashes with the V6 is a breeze. However, TTL will not work with Sony cameras.
The RF 60 is a powerful flash with GN56 plus a BUILT-IN transceiver. Power output and zoom level of RF60 can be controlled by V6 without having to add another V6 to the flash. It’s built-in transceiver also means that an RF60 can control another RF60 directly without having to add any flash trigger to it.
