HSS on the V6 Mk1

Hi Antonio,

A customer has called to say that he's seen mention online somewhere that an upcoming Cactus update will allow HSS in the Mk1... is that right? 

Big thanks<



  • He is working with Fuji and Nissin.
  • Hi Blaise,

    The original V6 only supports POWER SYNC high speed sync mode when it is used as a RX.

    Power Sync fires a full power boost, and not the typcial pulsing flash signal used in HSS.

    Using the latest firmware version on the V6 wil support this. Simply set POWER SYNC on a V6 II TX unit, and a V6 RX can fire a flash and sync with camera in above x-sync speeds.

    Hope this helps!

    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.
