CACTUS – V6 II & V6 IIs Transceivers with HSS Announced



Cactus have announced the second generation of their original V6 radio transceivers, now adding High Speed Sync (HSS) to the unique cross brand flash triggers.

The same Cactus V6 II transceivers will now provide remote HSS function while using Canon, Nikon, Olympus, Panasonic, Pentax, and most interestingly, Fujifilm cameras!

UPDATE – June 2018 – The V6 II / V6IIs and X-TTL system now supports full TTL metering, with Canon, Nikon, Fuji, Pentax, Olympus, Panasonic, Sigma, and Sony (with V6 IIs).




And separate Cactus V6 IIs transceivers designed for Sony cameras and flashes, will also enable remote HSS with Sony cameras and speedlites providing a Multi Interface Hotshoe .




Other new Cactus V6 II and V6 IIs features include –


  • AF Assist Light (mainly functions with DSLR cameras rather than mirrorless)
  • 2 HSS Modes – Normal HSS, and Power Sync (Long Duration Sync)
  • Auto Detect – Automatically senses camera and flash types being used
  • Remote Flash Zoom Control – Of all compatible TTL speedlites
  • HSS and Power Sync with Cactus RF60 speedlites


The V6 II are now bringing previously unavailable remote HSS functionality to the Olympus, Panasonic, Pentax, and Fujifilm camera users, while still providing the option for an on-camera TTL speedlight if desired.

When the first Cactus V6 were originally released there was a lot of confusion around their functions. And the original release post here will help to provides more insight into their unique feature set.

The V6, and now V6II/s, are primarily remote manual radio triggers only. UPDATE – now also provide automatic TTL metering

They do however, when used as a transmitter unit mounted on the camera hotshoe, provide a pass through hotshoe which will allow a flash to operate in TTL mode while mounted on the camera.

And now HSS function with remote slave flashes.



The other unique feature of the V6, V6 II, and V6 IIs transceivers is the ability to control the remote manual power levels, zoom control, and now HSS function, of TTL speedlights from other camera brands.

So Canon, Nikon, Fujifilm, Olympus, Panasonic and Pentax speedlights can all be fired and controlled at the same time from the one camera and transmitter unit (or even multiple cameras).

And the V6 II transceivers can now auto detect which flash is being used, instead of the flashes profile having to be manually selected.


Cactus also have their own RF60 speedlites with V6 II compatible radio receiver built inside. And the RF60 can now provide HSS and Power Sync via the V6 II and V6 IIs transmitters.

(Previously sold RF60 may require a user enabled firmware update).







Please see the original Cactus V6 overview here for more details and specs on the V6 transceiver system.




The Cactus V6 II and V6 IIs transceivers are available now for $95.00 each –

    As a Fujifilm user, I am SO looking forward to these!

  2. stefano ruffini 5 years ago

    Any idea if they will be able to work with the old v6?
    One v6ii as transmitter will be enough to have his?

      Hi Stefano,

      The original V6 should certainly be compatible.

      And as you say one V6 II as transmitter will likely do the trick to provide the HSS pre-sync signal to your existing V6 as receivers.

      Finer details like whether the original V6 receivers can enable the HSS mode on various TTL flashes I’m not sure.

      I would suspect, like the RF60 flash, the original V6 may require a firmware update.

      • marco 5 years ago

        Hope they will add support for godox ad180/360 ad the new 600 series. Would be great to have an hss option for fuji and pentax user..

          Hi Marco,

          That’s the main thing I was thinking regarding the AD360II-C/N. It will be a big advantage if Cactus can build a profile for those to work directly with the V6 II transmitter and receiver.

          The AD600 should provide HSS, or Long Duration Sync, as long as they can get that pre-sync fire signal. Though the AD600 don’t have any hotshoe, so there definitely won’t be any remote power control through the Cactus V6 II transmitter.

          • Antonio 5 years ago

            Hey Elvis, there’s not really a need to build flash profiles per se because the V6 II can now auto-detect these digital-TTL flash / speedlights. 🙂

              Ok thanks Antonio.

              So do you know if the AD360II-C and/or AD360II-N will have full control via the V6 II ?

              As in remote manual power control, and HSS and/or Power Sync?

              • Antonio 5 years ago

                We tested on the AD360II-C and it worked fine.
                As for the Nikon version, we are guessing 99% it will work as well. 😉

        • Antonio 5 years ago

          Hey Marco,

          Yuppers. Both the Godox AD180 and AD360 (C/N) are compatible with the V6 II.

          Plus, you will be able to shoot at above camera’s x-sync speed on your Fujiflm and Pentax cameras.


          • marco 5 years ago

            That’s a great news. I imagine with the original ad360, with no ttl support i can’t remotely aadjus the power. But it will support hss?

            • Mikko 5 years ago

              Do we know for sure that these work with original ad180 (not ttl) model? Hope so!

                Hi Mikko,

                When you say work, they can only fire the flash. (And provide the early fire signal for HSS use if desired).

                For remote power control you still need the clip on Godox triggers, 433MHz FT16 or 2.4GHz XT16.

    I’m using MFT and such a solution was a long missing feature for this system! Order is done as soon as possible.

  4. Julio 5 years ago

    I just want to make sure about my setup before I buy: I use an A7R2 and I was a Canon shooter. So my question is: Can I use my A7R2 with my Canon 580EX II flashes with the V6 IIs?

    • Antonio 5 years ago

      Hi Julio,
      You will need the “V6 IIs” – the little “s” is for Sony. The V6 IIs will be available later in July.
      And yes, you will be able to trigger your Canon 580EXII with remote power control, remote zoom control, Normal HSS and Power Sync, all on your Sony A7R2. 🙂

        Hi Antonio,

        Can you (or should you) use a V6 II as receiver though for the 580EX II? (as they have a regular (non sony) foot).

        With V6 IIs as transmitter on the camera.

        • Antonio 5 years ago

          For Sony camera or Sony system flashes, mount a “V6 IIs”
          Whilst for all other compatible cameras and flashes should be mounted on “V6 II”.

          In Julio’s case…
          he would need a “V6 IIs” for his A7R2
          and a “V6 II” for his 580EXII

          • Peter Kent 5 years ago

            Thanks for all the info so far but I got a tough question. I also moved from Canon to Sony, I currently shoot with an A6300 but have a set of Yongnuo YN600s with their YN-E3-RT remote radio trigger.

            Can I put a “V6-IIS” on my A6300 then the Yongnuo YN-E3-RT Transmitter on the V6-IIS’ hot shoe to control my Yongnuo flashes?


      • dale 4 years ago

        antonio, so for the v6ii for the canon 580ex ii, i have this setup but is there any way to remotely change the power or zoom head? all i can see is the power changing on the transmitter and receiver screens but the flash fires at whatever i manually set on the flash, no changes take effect. thx

  5. Antonio 5 years ago

    Hi Stefano,
    The original V6 is indeed compatible, but not on the current firmware.
    After firmware updating (still in the works) of the V6, setting one V6 II as a transmitter and V6 as receiver will only give you Power Sync. Unfortuantely the V6 cannot support Normal HSS (the typical long pulsing flash on HSS / FP mode). That said, RF60 will support both Power Sync and Normal HSS.

  6. Donald F. 5 years ago

    I can fully confirm that Godox flashes does work with Cactus V6 II with Fujifilm system!!! Watch my video for proof!

    I highly recommended this trigger!! Works perfect with my Canon DSLR as well. I will make more videos regarding PowerSync Mode.

  7. Dimitris Servis 5 years ago

    Selling a set of Elinchrom lights after that (I will keep the beautiful modifiers)

  8. Eder Acevedo 5 years ago

    Will this be compatible with LUMIX cameras? I know it says that is compatible with many flashes, but it doesn’t says much about camera bodies..!!

  9. Donald F. 5 years ago


    Putting XT32C 2.4Ghz or FT-16s 433Mhz on top of Cactus V6 Mark II trigger will enable HSS/Supersync on all brands like Panasonic, Olympus, Fujifilm, Pentax, Nikon, and Canon when using Godox strobes and flashes. For Sony, you will need Cactus V6 Mark IIs (For Sony).

  10. NIgel B 5 years ago

    I have a Fujifilm XT-10, 2 Yongnuo 568EX II speed lights and 3 Cactus V6 II transceivers.
    Will this setup (1 transceiver on the camera hotshoe (in TX mode), I transceiver on each of the 568 EX II speedlights (set in RX mode), will I have HSS, Supersync, or Powersync functionality?
    Will I be able to shoot above the normal camera flash sync speed of 180th/sec?

  11. Andy 5 years ago

    Is it possible to use the v6 mkii on a fuji camera with a Godox TT685 flash on top of the v6 mkii? Will it feed the ttl signal through the transceiver or will it only work off camera with another transceiver connected to the godox flash?

  12. Zinc 5 years ago

    Will this be able to trigger yongnuo 560iii and ivs,
    And if yes, with remote control over power/zoom?

  13. Ranjith Wijekoon 4 years ago

    I use fuji XT2. I have legacy flashes from Metz – 40mz2, Pentax version of Metz 50-Af1 and Nissin i40 (Fuji version).

    Will I be able to use all or some of these with TTL/HSS control with Cactus V6iis on my Xt2.


  14. Norman 4 years ago

    Just bought 3 of the Godox V860iio for the Panasonic GH4, can you control manually the zoom of the V860ii off camera with the V6II, also can you control all the Godox flash functions, TTL, Slave, HSS, Manual, Groups and channels?

    • Author

      Hi Norman,

      Sorry I’m not sure on that. You may have to check with Cactus. I’m not sure if they have even rolled out TTL for Olympus just yet.

      You do realize working this way you would need a V6 II transceiver attached to the foot of each flash?, where the Godox X1T-O transmitter will function with the radio receiver built inside the V860IIo etc.

  15. Mark Kitaoka 4 years ago

    I can confirm that the Cactus v6II works in HSS with the Pentax 645Z using Godox strobes. You can read how it works on my blog.

  16. Neil 4 years ago

    The trouble with these units is that they do not support any of the wireless protocols used by the other manufacturers. At the moment they cost more that the TT685 flashes I just bought, so I will just have to wait for Godox to release a trigger with a better UI that the X1T
