V6 II doesn't work with RF60 on Canon 6D and 5D Mark III

I have V6 II and four RF60. With other system (Olympus M5 Mark II and M5) works perfectly!
I update V6 II to Canon firmware and RF60 to the latest. The speedlight did not fire when I try to make a photo. With test button, the speedlight fire.

What is the trick to make them works together ?!?

Thank you!



  • Hi Mihail,

    Could you confirm the exact firmware version installed on both the V6 II and RF60?

    In the meantime, please try the Status Screen Check (camera info):

    So to confirm there's indeed a good hot shoe connection between your Canon cameras and the V6 II (transmitter).

    Thank you!

    To help us better help you, always state the exact firmware version installed on your Cactus device(s), such as: "1.1.013", "NIK.A.001", "v.103", or "A06".

    TTL or HSS not working on Cactus V6 II and V6 IIs? Be sure to check hot shoe connectivity by doing the <CAMERA INFO> check.
