This hot shoe adapter mount lets you control studio flashes, even syncing your PC to your flash trigger and studio lights simultaneously with a cable. It is compatible with Canon, Nikon, or any third-party flashes. With PC Connection, you can activate both flash and studio lights by connecting either: a) studio light with a 3.5 PC connecting cable & trigger; or b) flash a PC-to-PC connecting cable & trigger. Compatible with Sony A7, A7S, A7SII, A7R, A7RII, A7II, NEX6, RX1, RX1R, RX10, RX100II, HX50, A6300, A9 Mirrorless Cameras. However, it is not compatible with Sony A6000 because that model needs a certain accessory that this hot shoe flash adapter does not have.
