DIYP Reviews the Cactus V6 Wireless Flash Radio Trigger System

Most photographers have a mix of gear from many different brands.

For example, it is not uncommon for a photographer to have both Canon and Nikon camera bodies, a mix of Canon and Nikon speedlite strobes, maybe some third party speedlite strobes like Yongnuo or Nissin and studio strobes.

If that is you, you will want to check out the new Cactus V6 wireless flash radio triggers.  According to Cactus:

The Cactus V6 is the World’s First wireless flash trigger that works ON ANY CAMERA (with a standard hot shoe or PC Sync port) to control power output, wirelessly, of Canon, Nikon and Pentax’s system flashes ALL AT THE SAME TIME.

We put the Cactus V6 triggers through their paces – read on for our review of the Cactus V6 wireless flash radio trigger system.

Triggering Off Camera Strobes In A Multi-Brand Environment

Up until now, the only option to trigger a mix of strobes from different manufacturers was to use full manual radio triggers such as the PocketWizard Plus III or Plus X transceivers, or to set up brand specific triggers like the Pocket Wizard Flex TT5 to work in full manual (click here to find out how).

The new Cactus V6 wireless flash radio triggers are specifically built to work in a multi-brand environment.

And, they can control the power of your remote off camera strobes, right from the Cactus V6 on your camera (well for Canon, Nikon or Pentax and their clones anyway).

To me, that is pretty awesome!

Wireless Power Control is Not TTL

Just to be clear – the Cactus V6 triggers do not offer wireless TTL control.  But they do offer wireless manual control (which to me is much more useful than TTL anyway).

What that means is that once you set up your off camera strobes, you can manually dial the strobe power levels up or down for each individual flash, or for the entire group.

Here is a list of comparable flash models pre-installed on the V6:

Canon system models:
- Cactus AF45C, AF50C;
- Canon 320EX, 430EX, 430EXII, 540EZ, 580EX, 580EXII, 600EX-RT;
- Godox V860C;
- Metz 36AF-5, 44AF-1, 50AF-1, 52AF-1, 58AF-1, 58AF-2;
- Nissin Di866 MARK II, MG8000;
- Phottix Mitros;
- Sigma EF-500 DG SUPER;
- Yongnuo YN568EX II;

Nikon system models:
- Cactus AF45N, AF50N;
- Metz 36AF-5, 44AF-1, 58AF-2;
- Nikon SB-24, SB-28, SB-600, SB-700, SB-800, SB-900, SB-910;
- Nissin Di700, Di866;
- Sigma EF-530 DG SUPER;

Pentax system models:
- Cactus AF45P, AF50P;
- Metz 36AF-5, 44AF-1, 50AF-1, 58AF-2;
- Pentax AF 360FGZ, AF 540FGZ;

If a TTL flash model is not listed, the V6 may still be able to learn its flash profile and then be able to control the power output of the flash.

Other Features

Here are a few other features of the Cactus V6 wireless flash radio trigger system that I found particularly interesting:

Absolute Power Control

Absolute Power Control benchmarks the power output of different flash models to the same light intensity.  What this means is that your big Nikon SB-910 will output the same power as say a Canon 430 EX II when they are used together in the same system.

Lo Power mode

Lo Power Mode fires the flash for extremely short lengths of time so the flash power is less than the minimum power setting.  This would be useful for high ISO, low light photography, where a flash power of even 1/128 is too bright.

Remote Shutter Release

With a shutter release cable, the Cactus V6s can also be used as a remote shutter release.

In The Box

OK – now that we have established why the Cactus V6 wireless flash radio trigger system is a powerful tool, lets take a look at how they look and how they work.

In the box you get the Cactus V6 wireless flash tranceiver, a cold shoe mount, an instruction booklet and a booklet of sample photographs with lighting diagrams.

I particularly appreciate the inclusion of a paper instruction booklet.  Most modern electronic devices seem to only have an online manual, which to me, is usually a big pain in the a$$ compared to a little paper instruction booklet.

Build Quality

The Cactus V6 wireless radio triggers look very similar to PocketWizard Flex TT5 tranceivers.  They both take two AA batteries and are about the same size and shape.

I would say that the overall build quality is very similar to other radio trigger systems I have used such as PocketWizard and Elinchrom Skyports.  All of the buttons and the control dial feel firm and functional and the hot shoe mount is sturdy.  I also really like the hot shoe locking mechanism – there is minimal play once locked down.

Performance In The Field

The real question is how the Cactus V6 wireless radio trigger system performs in the field.  In this regard, when Cactus asked us to review the V6s, I have to admit that I was initially pretty skeptical.

After all, the Cactus brand is a subset of Gadget Infinity (or Gadget Infamy), a well known supplier of low cost Chinese radio triggers with a questionable record of reliability.

Past reputation aside, I had a very positive experience using the Cactus V6 radio triggers in the field – although I did discover a few quirks with the system.

Update: Cactus and Gadget Infinity are separate brands under the mother company Harvest One Limited.  The Cactus V6 was developed independently by Cactus with over two years of design and testing in Hong Kong.  The V6 units are assembled in mainland China.

Multi Brand Lighting Setup

To test out the Cactus V6 radio triggers, I decided to use them on a shoot for a local fitness studio that would involve several different strobes.

Here is a of one of the lovely pole dancing fitness instructors from that shoot.

In this image, the model is lit by the following:

  • An Elinchrom BRX 500 studio strobe triggered by a Cactus V6 in manual mode from behind and to camera left,
  • An Elinchrom BRX 250 studio strobe triggered by optical slave from behind and to camera right,
  • A Nikon SB-800 off camera flash triggered by a Cactus V6 with remote power control overhead,
  • And a Spiffy Gear Light Blaster is projecting the stars onto the background with a Canon 430 EX II speedlite triggered by a Cactus V6 with remote power control.

(For a details of the complete pole dancing fitness instructor shoot and a lighting diagram click here).

Cactus V6 Manual Mode Performance

In manual mode, the Cactus V6 triggers were bombproof.  I didn’t notice a single misfire of the studio strobes.

Of course, I was not really testing the range of the system, or the limitations of the system in a wifi congested environment, but we were on location and shooting for nearly four hours, so I’d say the performance was great.

Cactus V6 Power Control Performance

On the Canon 430 EX II, the Cactus V6 triggers worked like a charm.  I was able to control the power output of my remote flash right from the V6 on camera without any problems.

However, I did have a few issues with the Cactus V6 and my Nikon SB-800s.

First of all, with a Nikon SB-800, I found that the V6 would only work if I turned on the flash first, then the V6.  This isn’t really a problem once you figure it out, but it was a little frustrating at first (my Pocket Wizard TT5s have the same issue).

Next, when connected to the V6 the controls on the SB-800 are completely locked – you can’t even turn the flash off.  I also noticed that once connected to the V6, the flash head would fully zoom in to 105mm.  I managed to fix the zoom problem by turning off the automatic power zoom head function on the SB-800 – but then you have to remember to set the zoom before turning on the V6 because the zoom control will be locked.

Finally, the SB-800 did not always fire correctly.  With a new setup, I would occasionally get a tiny flash, well below minimum power, regardless of what power setting the V6 transmitter was set to.  The V6s were triggering the flash, but only at a very low power pop.  The only way I could work around this was to turn the V6s off and on a number of times until it would work correctly.  However, once the system was working correctly, it continued to work and I was able to control the power output of my remote flash right from the V6 on camera without any further problems.

I suspect that this may have just been a connectivity issue with my older and well used Nikon SB-800s, but I did mention my problems to Cactus and they are looking into it.  I will update this post if any new information becomes available.

Ease Of Use

Overall the Cactus V6 wireless flash radio trigger system was easy to use.

Each V6 is a tranceiver – so it can be used as either a transmitter or receiver – but you have to remember to switch it to the correct mode.  The V6 on camera is set to TX (transmitter), the V6s on your remote strobes are set to RX (receiver).

In manual mode, the V6s are ready to go out of the box.  To connect them to a speedlite strobe, you just put the flash on the hotshoe.  To connect them to a studio strobe, you have to use a 3.5mm sync cable.

In power control mode, you have to set each receiver to work with the specific flash it will trigger.  For example, if you are using a Canon 600EX-RT and a Nikon SB-910, you have to set one receiver to Canon 600EX-RT and the other to Nikon SB-910.  If you swap a flash for another unit, you have to remember to change the setting on the V6.

If you are pairing your V6s with the strobes you already have, I think it would be helpful to just put a sticker on each V6 to identify which flash it is set to work with.

Would You Recommend the Cactus V6 Radio Triggers To A Friend?

With a retail price of only $55 each, or practically half the price of PocketWizard’s lowest cost radio trigger option the Plus X, its hard not to recommend the V6s.

They worked flawlessly for me on manual mode which is all a Plus X can do anyway.

However, the V6s have a maximum advertised range of 100m compared to 500m for the Plus X – so PocketWizard is still the champ for long range reliability.

I did have some minor problems using the V6s to remotely control the power of my off camera Nikon SB-800 strobes, and those problems did effect my shoot.

However, the ability to control the power of your off camera strobes directly from your camera is extremely useful, so I would be willing to work with a few quirks in the system.

So the answer would be yes, I would recommend the Cactus V6 wireless trigger system to a friend.

At this price point, you really can’t go wrong, especially if you are already operating in a multi-brand environment.

Cactus V6 vs PocketWizard Mini TT1 / Flex TT5

Unless you are shooting long range in a congested wifi environment, or you absolutely need TTL (c’mon who actually needs TTL), I would definitely consider the Cactus V6 versus a PocketWizard Mini TT1 / Flex TT5 setup.

PocketWizard is a great company with fantastic tech support – but I have found the Mini TT1 / Flex TT5 setup to be quirky at best, totally unreliable at worst.

Plus, if you want to manually control your remote off camera flashes with the PocketWizard Mini TT1 / Flex TT5 setup, you need to have a flash in commander mode (or a commander module) on camera.  With the V6′s you don’t need another device on camera to act as a commander.

Finally, for the cost of a single PocketWizard Mini TT1 / Flex TT5 pair, you could get about eight Cactus V6s.

But, before you go out and sell your PocketWizards and convert your whole studio over to Cactus V6s, I would consider purchasing a few and trying them out with the particular strobes you are already using to make sure they meet your needs.

Update

I just used the Cactus V6s to photograph the IFSC Climbing World Cup Boulder Competition (see the photos here) which was a much better test of the V6s in a wifi congested long range application.

Alex Puccio IFSC bouldering world cup, gravity climbing gym, jp danko, toronto  commercity photographer

I set up two groups of strobes – one with the Cactus V6s and the other with Pocket Wizards, all triggered from the same camera.  In my initial setup, the V6s were set to remote power control of my Nikon SB-800 strobes and initially, I had no problems.

However, after a break in the competition, the V6s had gone into standby mode – and as they were inaccessible, there was no way I could wake them up.  At another  break, I was able to turn off sleep mode, and to make sure that I didn’t have any further problems, I set them all to manual trigger mode.

However, no matter what I did, I could not get the V6s to trigger my strobes in manual mode.  I don’t think this was a range or reception issue, the V6s seemed to be receiving the signal – they just wouldn’t pop the flash.

Luckily, the group of strobes that was set up with Pocket Wizards performed flawlessly – so I ended up using the Pocket Wizard group only.

I did a quick experiment – if a strobe is connected with a 3.5mm sync cable, the V6 seems to fire it in manual profile mode with no problems.  However, if the same strobe is on the V6 hotshoe, I cannot get it to fire in manual profile mode  – the flash profile has to be specifically set to match the strobe that is on the V6 hotshoe.

    But what about HSS??

    “Plus, if you want to manually control your remote off camera flashes with the PocketWizard Mini TT1 / Flex TT5 setup, you need to have a flash in commander mode (or a commander module) on camera.”

    Isn’t this what the AC3 is for? I manually control multiple flashes with my TT1+AC3/TT5s at every wedding I shoot and have never had anything set in commander mode. Will these V6s control power on multiple flashes/zones? I only see a single wheel on the back.

    • http://www.blurmediaphotography.com/ JP Danko

      You can control multiple strobes in up to 4 zones.

  • Bokeh Monk

    I was intrigued when I first learned of these ( great price ), but I can’t say that they offer me anything more then the Phottix Odin system I’m currently using ( Hi speed sync, zooming that hair light from the camera position, TTL control if ever I get lazy ). If these are your first venture into radio triggers, it’s hard to see a downside considering the price!

  • Brian Hursey

    In the update when you said manual trigger mode you mean the manual profile and not the one spacific to the flash? Think that could of caused a issue? With it not triggering?

    • http://www.blurmediaphotography.com/ JP Danko

      That’s right. In the manual profile they should trigger any flash. I didn’t have a problem in the manual profile with studio strobes – but those were connected with a 3.5mm cable – not directly to the hot shoe.

      • Brian Hursey

        That could of been it manual flash is designed for studio strobes with the 3.5mm I will have to test on my V6′s when I get home Saturday. I was a beta tester. Also BTW I was able to get 400+ meters on distance with them. Cactus said they got 800M on a river bank before they started having issues. I still think they should of marked it 200m instead of 100m.

        • http://www.blurmediaphotography.com/ JP Danko

          Works with various strobes via sync cable – doesn’t work with same strobe on hotshoe – so profile has to be set for flash to trigger on the hotshoe.

          • Brian Hursey

            Ok that would be why then. It was a bummer that it was not realized at the time. However I know how shoots are in a rush situation. I will talk to cactus to see if they can still have it send a signal to the hot shoe in manual mode.

          • Class A

            A signal is sent to the hot-shoe even when using the default “manual” profile.

            It seems like the SB-800 just weren’t happy to accept hot-shoe triggering.

            If the predefined SB-800 profile had been selected on the V6, I’m sure it would have worked.

            @JP: Make sure you are running the latest firmware (V1.0.152). If you are running Windows and have a respective USB cable (included with some flash models) it is very easy to update the firmware.

          • Brian Hursey

            I just tried it also on V1.0.152 with my most basic single pin strobe. My LP160 since I am now back from the beach. I know manual was originally designed for studio strobes connected via the sync cable. It looks like the hot shoe gets disabled for some reason as far as I can tell. I will ask cactus if this is by design or not, and see if the behavior can be changed in the future. Maybe even have a single pin flash option? I change the profile to like say a SB24 and the LP160 triggers.

          • Class A

            Brian, I don’t understand this. The manual profile was created for single pin flash models. It works for me just fine (on V1.0.152 and I even went back to V1.0.144 just for giggles; it works as well).

            If I use the Nissin Di866 (for Nikon) profile then my dumb flashes won’t fire but they all work fine with the “manual flash” profile.

          • Brian Hursey

            Class A list discuss on cactus’s forum.

          • Brian Hursey

            JP,

            Cactus says it should be fixed in upcoming firmware version 1.0.154 the manual profile is actually for any type of single pin flash or flash without a profile and should act the exact same as the trigger signal on a Cactus V5 however it looks like it is not currently.

          • Class A

            Firmware version V1.0.156 has been made available. Should fix the manual flash profile issue (that didn’t exist for me anyhow).

  • Marcus Wolschon

    So they work with Canon, Nikon and Pentax flashes but not with my Panasonic/Olympus/Leica Metz 58 AF-2 flashes?
    Why does nobody make Panasonic gear?

  • kenyee

    The PWTT can also remotely control power and do hyper sync with studio strobes. Just thought it was worth a mention since your comparing them directly….
    I prefer manual control of studio strobes and flashes myself…

  • michael

    Has anybody tried it on a Canon 50D ?

    • Rudy

      Yes it works on the 50D.
