Does 430EX III / 600EX master mode work in X-TTL ?

Hello there,

Just wondering, if I put Canon 430EX III on V6II on Fuji X-T1, 

can I set 430EX III in master mode to control other 430EX III ( with Canon RT system not Cactus ) ?

or the 430EX III can only set to TTL (get X-TTL ) or M ( manual control ) ?

Thanks !!


  • We never tried that, nor was the V6 II X-TTL firmware designed to work with another radio system at the same time. So we do not recommend such a setup > 430EXIII triggering other 430EXIII.

    But you can certainly mount a 430EXIII on a V6 II (TX) that is mounted on X-T1. You can let the camera do its thing and get TTL on-camera, or manually control its power output.  You toggle between these two modes by long-pressing the V6 II's Menu button for 2 seconds.

    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.
