CACTUS – Remote Manual Radio Flash & NEW V6 Transceivers Coming

Cactus Image, manufacturers of the popular Cactus V5 radio triggers, have announced they have a new manual flash unit with built in radio transceiver and remote manual power control. The new flash is expected to be available around the end of the year.

The new transceiver flash will act as either a transmitter or receiver, so one flash can control the manual power levels of other flashes set to receiver mode.

The new flash will also be compatible with the current V5 transceivers, as well as the LV5 laser trip trigger.

The current Cactus V5 transmitter will trigger the new flashes built in receiver, though the V5 can not adjust manual power levels on the flash.

(Note – this is not the actual flash design shown, as there are no images of the new flash available as yet) –

CACTUS Radio Flash & V5 Tranmsitter

Following the release of the radio enabled flash will also be a new Cactus V6 transceivers. The V6 when used as a transmitter will also allow remote manual power control of the new radio enabled flash.

Cactus are not giving away any more detail on the coming V6 triggers just yet. But we know Cactus very much like to keep their triggers single firing pin, and therefore universal for all cameras. Which is also very likely why the flash will be remote manual only and not TTL enabled.

So the new Cactus system should be another good option for many mirrorless camera users who do not have a dedicated radio flash system available.

Knowing the V6 will be transceiver units like the V5, transmitter and receiver are likely to be exactly the same units. This means its also highly likely they will have pass through hotshoes again (with single firing pin) like the current V5 –

A pass through hotshoe on the transmitter unit doesn’t leave a lot of options to locate an interface, which a flash mounted on top will not block. So its likely the V6 may have an interface at the rear of the case, possibly something like this –

Otherwise the less likely option could be an interface on top (as that would be fairly inaccessible with a flash mounted on top) –

Cactus will not confirm the V6 will even have an LCD interface at this point though, so (although a long shot) it may even possible the V6 could just have power level dials (a little like the channel dial seen on the side of the unit above).


The Cactus transceiver flash, and and Cactus V6 trigger, will likely be one of the few fully manual options to go head to head with the YongNuo YN-560 III flash with built in receiver. And coming YN-560TX transmitter, which will provide remote manual power control for the YN-560 III flash.

So far the main advantage we know of with the Cactus system is that one flash can control another, where the YN-560 III requires a separate transmitter. The V5’s also have some pretty solid engineering and sync speed, where YongNuo have been a bit slow previously.

Cactus are obviously wanting to start getting the message out to the many loyal V5 trigger owners now, that they will have a compatible radio flash alternative coming as well.

    I believe to pull this off with a LCD screen they will need to redesign the transceiver casing and mounting. Because right where the LCD screen is in the above image would be right where the current battery compartment is. They would either need a different place for a battery. They could put it toward the front however if you stuck a flash on top the LCD would be blocked. They could go with a power level dial on the side but I would imagine they would want some sort of grouping. I guess you could say change the channel dial then set the power then change to the next channel and so on. However that us cumbersome and not as quick as I would like. The way they do channels in the v5’s is they have the first few channels trigger all channels, and then the other ones past there are separate. So say you have one flash to channel 5 the second one to channel 6 and the third one to channel 7. Then you can change the dial to each flash channel firing them individually to test different parts of your light. Then you set the transceiver on camera to say channel 0 then it fires all of them. In regards to lcd positioning. The most room inside for components is up front. There is a bunch of space inside the case up there. Iv taken one apart However that then would be blocked by a flash if you put it on top of the transceiver on camera.

    Interesting, but will the flash on camera be manual-only, auto, or TTL?

      Hi Jacques,

      No the flash on camera will be manual only.

      Cactus like to keep it simple and universal, as that obviously keeps costs down and provides the greatest market.

      But you never know, they could offer a TTL flash later with the manual control built in. As I’m sure a lot of people will be asking for that.

      I doubt they will go to a TTL pass through hotshoe on the V6 (as they would not be universal then), but that could be another possibility.

        Sure wish we’d get a manual remote + compact “auto” on-camera solution for cross-platform and mirrorless use. The Triopo TR-850EX, these new Cactii, and the YN560 III look great in terms of the built-in remote output control. But, for event work manual on-camera flash is a drag, and full-size flashes make an m43 camera awkwardly top-heavy.

    Could the author perhaps provide an actual link to where the Cactus Image announce that they are going to make such a flash unit? There is no such info either at the website (manufacturer of Cactus products) or at

      Hi Zorzo,

      I spoke with Cactus directly, the flashes will be in beta testing soon. Its definitely real. There’s a couple of teaser images of the V6 here
      I’d say they will make an announcement when they are prepared to show a little more image and detail. Its still a couple of months away. Thanks.

        Well those teaser images look cool. Looks weather sealed to me!!!

    That’s great news then. I’m a Pentax user, and there are no wireless P-TTL triggers out there for us (except for the Aokatec ones), and that also means no way of controlling the flash power from the camera (other than through a P-TTL cable). If this turns out to be true, it would be really, really helpful. Actually, lately I’ve been trying to come up with some DIY solution for remotely adjusting the flash’s power in manual mode. Well, I guess I don’t have to anymore! 🙂

      Hi Zorzo,

      Another one to look out for is the Godox V850, they should be available within a couple of weeks. Even though I often describe the transmitter as a bit outdated, I can honestly say its the fastest and one I most prefer out of any of the TTL triggers otherwise.

      That’s not to say Cactus may not have something as good or better coming, but if you’re not invested in Cactus yet the V850 may be worth a look.

        Thanks for the tip, Flash Havoc. I only discovered this website yesterday, it’s in my bookmarks now, and it seems like I have some reading to do!

    Any guesses as to the cost of the Cactus flash? I’d be very interested in one if it’s somewhere in the Yongnuo to LumoPro range… Say $120.

      Hi Wil,

      I don’t know the prices, but I think its pretty safe to assume they will be in that $100 – $200 region. Considering the Godox V850 is $120 with Lithium battery and charger, they would want to be at least in a similar ballpark. Thanks.

    I am a tester on this product and they just aloud me to release a teaser image. You can view it here along with some features I was able to release. I wish my picture could show more, however its a teaser image and because the features are not finalized its hush hush tell our testing and reviews are done. More to come later on.

    Does anyone know if a Odin transmitter can work ttl with a canon 600 ex-rt without the Odin receiver?
