I have Sony A6600. I came from Canon, for wich I had two Yongnuo YN685 Speedlights, with YN622C Tranceiver to shoot wireless. I am ytying to use them with my new Sony. But I have a rare situation shooting Slave mode. It fires the test flash without problem from the tranceiver, but when I shoot from the camera, the flash fires once, and then the red link light on the speedlight turns on. Then it doesnt fire any more. Unless I turn off and on the speedligtth. And, again, it fires only once.
Any thougths.
