Cactus V6 Trigger is Capable of Being Used with Almost Any Flash System


Looking to change up the wireless flash trigger game, Cactus has announced its new V6, the world’s first wireless flash trigger that works on any camera with a standard hot shoe or PC Sync port. It can control Canon, Nikon, and Pentax systems all at the same time.

Capable of TTL passthrough with flashes that support it, the V6 allows the wireless flash to behave as though the flash were directly mounted on your DSLR. And even flash models that don’t have native TTL support, it’s possible for the V6 to learn the flash system’s profile and adjust the output levels accordingly (though, it’s not compatible with reversed polarity connectors).



The output adjustments can be made through a dedicated slider on the back of the V6, making it “the FASTEST on any manual system available in market,” according to Cactus. Not only is it fast though, it’s precise. According to Cactus, the V6 is capable of controlling power levels on certain flash models as low as 0.1EV, even if the flash itself doesn’t support such capabilities.


What really seems to set it apart is its ability to not only control various brands of flashes, but its ability to use a motley crew of brands while making sure they each put out the same, consistent level of output. This is done through the benchmarking of the models and including that in the individual profile which each device comes programmed with.


In the words of Cactus,

That means, photographer can ask a Nikon SB–910 and a Canon 430EX to emit the same intensity of light (in EV number), independent of the maximum power output of the models.


Other major features include low power mode, group control, a built-in optical trigger, relay mode for triggering shutter and flash in sync, delay timer, and a MiniUSB port.

With all of this technology packed into a fairly small package, you’re probably expecting a bit of a sting in the wallet area. But, not so much in the case of the V6. Coming in at only $55 over on Gadget Infinity, the V6 is as affordable as it is impressive with specs. For more information, you can head on over to the V6 microsite.

    I’ll wait for the reviews

  • Dream Art’s

    Interesting news :) will also wait to see if the new Cactus still work with Pana & Olympus as camera and the other flash brand (yongnuo…etc)

  • David Trevino

    How about pocket wizards, will it trigger those? There version sucks.

  • Fullstop

    Now this, is the good PetaPixel stuff ;)

  • bogorad

    Incredible everything, including the price! Thanks for the info!

  • Alex Tardif

    Anyone notice this “little” note?

    “… Notes on compatibility:
    Cactus V6 does not transmit TTL information wirelessly”


    Edit: wait, what? I’m confused? PP reports it does transmit TTL wireless, but their website says the opposite?

  • Gannon Burgett

    The TTL information is pre-programmed into the Cactus triggers. Thus, it doesn’t “transfer” that information as a Pocket Wizard would. It simply knows what flash is being used, then uses it’s internal database and your accompanying settings to send out a signal telling it what to fire.

    They share that for the sake of technicality. For all intents and purpose, it works as a standard TTL system would.

  • Class A

    No, the V6 do not trigger PWs.

  • Class A

    Several reviews (user reports) have been published already. Google is your friend.

  • Class A

    The camera only needs to supply a trigger signal through the hot-shoe; that should make virtually every model compatible.

    The flash system and brand can be any, as long as the V6 can support it through a predefined or user-created profile.

  • cardmaverick

    These are also compatible with the V5 units.

  • Alex Tardif

    Cool, thnx!

  • Rob Elliott

    Well it will do Canon TTL with the 568EX II (it’s the only Yongnuo listed)

    It will have the same functions as the V5 according to the Manual for everything else.

  • Daniel Effah

    So will it work for Sony DSLRs with standard hotshoes?

  • Brian Hursey

    YN568EX will work also with that profile I know I use it currently. For non analog profiles, cactus can look to add upon request via firmware.

  • Daniel Effah

    Will it work for the universal hotshoe for Sony?

  • Jonathan Maniago

    Although Cactus’s V6 Trigger + RF60 system looks rather tempting, none of their manuals mention having an AF assist lamp. Those who frequently shoot in low light might want to stick with Yonguo for now.

  • M. A. S.

    My patience is running out waiting for the YONGNUO YN-622C-TX. If in two months this trigger is not released, I will try these Cactus given by then online reviews are positive.

  • Chris Rogers

    Wow I was expecting this to be $500 or something.

  • Jenny Chen

    Did anyone see Mike Fulton demonstrate RadioPopper on CreativeLive? he was able to control the power of any flashes, even the continuous light! all from the commander knob on his camera, it was like Magic!
    How is this thing better than RadioPopper? hmm…

    If you mean the RadioPopper JrX then the V6 provides digital control in 0.1, 0.3, or 0.5 steps instead of using imprecise analogue knobs. It also features an absolute power mode that allows absolute light output independent of a flash’s maximum power. Google “Cactus V6 radiopopper” and you’ll find a complete comparison.

    Compared to the Radiopopper PX system, the V6 allows quick manual control by using just a dial and four buttons. It is also brand-agnostic and will thus allow you to mix and match flashes from different brands. Even your old TTL flashes have a good chance for receiving remote power control through the V6.

    The V6 does not support any automatic exposure control but there is no camera menu diving either.

  • Huey Gnash

    isn’t that controlled by camera setting not by flash?

  • Jonathan Maniago

    Yes, there is probably a camera setting for it, but your hardware should also support it.

    What I’m referring to is the infrared AF assist light. Some cameras (such as Nikon’s) have this built into the camera itself, but others (such as Canon’s) do not. In low light situations, shooters such as myself have to rely on additional hardware such as external flash or radio triggers (ex. YN-622C, shown below) for this feature.

    Of course, there’s still the option of using regular flash for helping in low light focusing, but those are painful for the subject’s eyes, and they don’t help at all if the subject has low contrast.

  • Richard Brown

    How about HSS?

  • Richard Brown

    Looks like sync speeds up to 1/1000 however that may not mean it will function well with HSS settings on say a 580EXll, probably worth testing for this price. Looks pretty good.

  • Brian Hursey

    You would need to use exclusive ttl protocol unfortunutly talking to cactus it’s an all or nothing thing so to have af assist light the system would need to be full canon or Nikon protocol throwing out universal compatability. You can not just take part of the ttl protocol. However piggybacking a YN622c on top in ttl pass through works predict adding af focus also it can provide the fp hss signal to the v6 to either trigger a RF60 in HSS mode or do hyper sync.

  • Ed van Wageningen

    Will these support analoge fkashes without frying the triggers?
    If so, I might upgrade my V4’s, those do accept analoge flashes without frying them.

  • Class A

    They have the same trigger voltage tolerance as the V4 (300V).

  • Peter Koerhuis

    The V5 (and LV5) can also trigger the V6.

  • Peter Koerhuis

    If by “standard hotshoes” you mean Sony’s “new” hotshoe (Multi Interface Shoe), then yes, those flashes can be triggered. But the V6 cannot control the power of any Sony flashes.

  • Peter Koerhuis

    The stated maximum sync speed of 1/1000 is for regular flash (without HSS). With an on-camera V6 in TTL pass-through mode, the flash on the V6 will have all E-TTL II features including HSS at 1/8000 shutter speed (tested on 5D mkIII with 580EXII and 600EX-RT).

  • Marc W.

    Not “analog”, but “high voltage” flashes.

  • Rodney Ballard

    Peter, were both of these two flashes OFF camera when tested to 1/8000? And on camera was only a V6 transceiver?

  • Peter Koerhuis

    Rodney, both flashes were on the hotshoe of a V6 on the hotshoe of the camera, with the V6 in transmitter mode and TTL pass-through enabled. 1/8000 can only be achieved with HSS, which requires TTL. The V6 doesn’t support wireless TTL, only TTL pass-through.

  • Russell Wright

    Can the V6 trigger an AlienBee B800?

  • Gary Blake

    Thanks for the information, Brian. I should have done more research before buying these. I assumed that since my old system had full TTL passthrough that this would as well. It was a huge letdown to see that it doesn’t.

    Can you explain the YN622c setup a little more? Maybe a photo?

  • Brian Hursey

    Gary, TTL passthrough not working for you? Did you make sure to set the flash profile on the TX and hold down the menu button so it switched into TTL passthrough. It should work at that point.. The YN622C I just put it on top of the V6 and set the profile on the TX trigger to YN568EX.. and selected passthrough. Some people have made that mistake and assume it just does not work and they just were not doing the process.

  • Brian Hursey

    Via sync cable but wont conrtol power.. I have used them on my AB400.

  • Russell Wright

    Brian thanks for the info. I plan to purchase the AB800 soon and was wondering if I could use the V6 to trigger it. I’m not worried about not being able to change the power settings via the V6. So, will I need a sync cable adapter? If so, would I mount it on the camera hot shoe, or the V6 hot shoe?
