CONONMARK – ABC TTL Transmitter For K4T Strobe Released

Cononmk K4T


Chinese flash manufacturer Cononmark have released a new ABC transmitter unit for Canon, Nikon, and Sony DSLR systems, compatible with their TTL and HSS enabled K4T leopard portable strobe unit.

The Lithium-ion powered 400WS K4T Leopard strobes have been available for close to a year now with Canon and Nikon TTL and HSS compatibility.

Though despite actually being one of the first TTL and HSS enabled strobes available, the K4T have not received much attention, likely due largely to the rudimentary 3G transmitter unit previously required.

The new ABC transmitter unit now looks to change that. And also quite significantly adds Sony compatibility to a TTL and HSS enabled 400WS strobe for the first time available.

The K4T Leopard strobes have the TTL and HSS enabled radio receiver module built directly inside the flash, so no extra external receivers are needed.

And the one K4T strobe is compatible with Canon, Nikon, and Sony DSLR systems.

Separate ABC transmitter units are needed to function on each camera system though.

Cononmk K4T



If you may not be familiar with Cononmark lights already, they have previously been one of the most prominent compact manual battery powered portable strobes available over the last 5 years or so. Generally sold under a number of re-brands like Impact, Photoflex, and Phottix etc.

With the new ABC transmitter, the TTL and HSS enabled K4T are looking to be a much more interesting offering now as well.





The Cononmk ABC transmitters units are available now from $99.

And the K4T Leopard strobes from $800.

Contact Cononmark directly at, or Skype#queok8, for purchasing directly.

Or see the Cononmark Ebay Store.

    Very interesting. The flash tube is recessed within a fixed small reflector dish. This is OK up to a point and probably augments the 400Ws claim. But I doubt that the light spread will remain ideal when a Bowen S converter is added. Still it may soften the Indra 500 pricing a little.

      Hi Donald,

      Yes they do make a number of models with the Bowen’s mount as standard. And I think going that way is likely the only way this light is really going to gain a lot of traction.

      I can see why they use the Comet mount though, as these lights are really quite compact and lightweight. The Indra is almost twice the weight.

      It will be interesting to compare them side by side.

    Its great that manufactures are noticing that there is a market for Sony.
    I’m surprised to learn they produce & brand the Phottix gear!

    At the same time we are also getting off camera wireless flashes/speed lights announced by Nissin:—nas–nissin-air-system-air-1-di700a.html

    Sony users previously had a few wireless choices:
    -manual off camera flash
    -Phottix Odin (minolta mount)
    -Pixel King Pro (minolta mount)

    A year or two ago, Nicefoto had announced they were going to release the 316 & 318 but that never happened (I believe the 316 got released for Canon only).

    Right now for Sony, I’m either using manual wireless (studio) or IR wireless / on camera flash from the new Sony 32 (which suits the cameras perfectly and gives you IR control of groups, I’m very happy with this flash), to trigger some 58’s…should people be looking for ideas. We don’t even have an off camera TTL flash sync chord for the new mount.

      Hi Johnson,

      Phottix only have that one PPL series of light from Cononmk, and I’d be surprised if they are not intending to completely replace those with their own lights eventually.

      The Cononmk lights were really one of the only main options available, so they were re-branded by many companies. Now the Godox Witstro have become a lot more popular in this area, and there are many re-brands of those now available.

      The mini monolight format still has a lot to offer though (with swivel and modifier mount built in), they just need to get up to speed with the rest of the features as they are trying to do here.

      Regarding Sony, I have just bought an A7 myself, as that seems to be the end of the mirrorless market that is growing fast now. So that is going to be a bit of an ongoing project to see what is possible with triggers and lighting options.

    I wonder if these will be marketed under the Impact line (I believe the LiteTrek is Comet mount).

    The next year or so should be very interesting for portable strobes.

      Hi Earle,

      Its highly likely a lot of brands will want to get on the TTL strobe bandwagon, and once again there will likely not be that many original options to choose from. So a lot of brands will likely pick these up, as well as the Godox units once their TTL models are available.

      I’m not sure if Phottix do much in the way of OEM for other brands. Strangely YongNuo don’t do it too often either.

  4. PonyMa 5 years ago

    K4T is a very exciting outdoor photo flash. Full-featured powerful / small and easy to carry / cheaper reasonable price. I spent almost a year of his time, very satisfied

  5. Ricardo 5 years ago

    NICE little system. Love the size. You can probably fit one or two of these (without the reflectors) in a rolling camera case. 400W is also a good range too. I’ve rarely needed anything beyond what a speedilte produces for a single-person shoot. The power comes in handy for bigger modifiers though.

    I’m glad to see manufacturers putting dedicated buttons for channels in conjunction with LCDs on the controller. If you’re an amateur, it’s not a big deal to remember a process for selecting channels and making adjustments. But for pros and you’re ‘in the moment’, it seriously slows you down. I’ll be upgrading to the Odin IIs asap 🙂

      Hi Ricardo,

      Without the reflector these are not much bigger than a speedlite folded (plus the battery pack of course).

      I don’t know why these companies don’t offer a nice little reflector option though, as you could certainly fit 3 of these complete units in one bag then. The Rovelight 5″ reflector is certainly a more practical option in many cases, but with this light you could go even smaller.

      Yes the transmitter is a big improvement. Anyone should be able to pick these up and operate the basic functions without going to a user manual to figure it out. And I don’t have a manual for the ABC trigger anyway 🙂

      It even has a master option though, where you can select which group is always ready to go for setting changes. So no need to press that group button first for that group, just go straight to the + or – adjustments.

    Ok this is getting interesting, a courier just arrived with the K4T a few hours ago. Cononmk said they could send a sample to test but I didn’t realise it would be that quick.

    What is interesting though is that the K4T is providing 0.2 stops more light than the Phottix Indra !

    In HSS the output is pretty close to equal.

    I tried removing the frosted glass dome on the Indra and that made no difference to the output. The built in reflector is no doubt giving the K4T the advantage.

    Its interesting though because the K4T is considerably smaller and lighter.

    The K4T modelling light is also considerably brighter than the Indra.


    The ABC trigger is working will with Nikon, though I need to use +2 FEC on the D7000 to match a regular exposure with a Nikon speedlight. FEC works correctly on the ABC trigger, but not from the Camera FEC adjustment at all.

    Canon is the opposite, FEC works from the camera adjustment, but FEC settings on the ABC trigger are not as large as they should be (about 1/2), or consistent between increments.

    Sony, I will need to get an Multi Interface to Minolta shoe adapter for the transmitter they have sent, before testing that.

    The ABC trigger works very well though otherwise, and very fast to adjust.

    (The Indra is also requiring some FEC adjustment to achieve a regular TTL exposure by the way, depending on which camera model is used. Though FEC adjustments appear very good.)

    What is also interesting is that you can literally use Canon, Nikon, and Sony cameras with the K4T light at the same time!

    With the Indra you need to set the flash to Odin Canon or Nikon RX Mode, so only one brand of camera can be used at once.

    So this is big help with the K4T for anyone using 2 (or 3) camera brands at once.


    Also it turns out there is a good purpose designed Bowen’s adapter available that doesn’t add too much extra depth.

    And thanks for the help from Pony Ma who commented above. He is from Taiwan and has been using the K4T for about a year now (great work here). And now using Canon, Nikon, and Sony systems with the K4T.

      Very interesting! Thanks for the quick update/preview. These are bit out of my price range at the moment but the combo of power, size, and flexibility is compelling.

    • Earle 5 years ago

      Thanks! This little taste makes the light more intriging. I’ll be curious to see how it fares when you do a more comprehensive test.

      • Author
        Flash Havoc 5 years ago

        Thanks yes I’ll have to go through the power level consistency and color etc in more depth to see how they really compare in function. The Indra are a bit more refined with the TTL at this stage though.

        Don’t get me wrong either though, the Indra are built like a work of art, and Phottix are really leading the world now with the only light of this kind that can be controlled by an on-camera flash. The Indra also provide an AC power option, where the K4T are battery only.

        So theres no doubt the Indra worth the extra money. But not everyone is in the market for a $1200 light, so Cononmk have thrown up an interesting option now that this new transmitter is available.

        If they came up with a YN-622 like TTL receiver unit for your speedlites as well this would broaden the appeal of these even further. Where Phottix are already ahead in that area as well.

        • Keano 5 years ago

          Have you tried the indra with nikon d750? Do you find it under or over exposes? Is the Indra long flash? Thx

          • Author
            Flash Havoc 5 years ago

            Sorry no I don’t have the Odin transmitter for Nikon as yet. At this stage I would prefer to wait for the Odin II to be available if possible.

            I only have a Nikon D7000 (and D70s) at this stage as well. I’ve really only just started with Nikon and Sony gear myself.

    Would TTL work with HSS?

      Hi Yo,

      Yes HSS works in both TTL and manual mode.

  8. Robbert Dijkstra 5 years ago

    I can confirm that Cononmk and Phottix have cooperated while developing the K4T. I cannot say how much, but my sources say they have.

    Any idea when this thing will be released?

      Hi Warren,

      I’ll try and check with Cononmk. I can’t see the K4T light for sale anywhere at the moment either.

      Its a nice system now though, particularly for Sony users (or Canon &/or Nikon &/or Sony users).

  10. RVN 5 years ago

    this great news for sony user who want strobe lighting with TTL, HSS and huge power ability, i hope other company like profoto, broncolor, elinchrom, etc follow them and add sony for their new market

  11. Donald 5 years ago

    Can you please check to see if the ABC trigger will trigger the Phottox Mitros+ flashes in TTL mode? Right now there isn’t a trigger without an adapter (Odin+adapter)…

    • Author
      Flash Havoc 5 years ago

      Hi Donald,

      I assume you’re meaning the ABC transmitter for Sony? Unfortunately I don’t have a Mitros+ for Sony to check this with.

      I think the chances the systems would be compatible would be a million to one though anyway unfortunately.

      EDIT – I checked the Canon ABC transmitter with the Canon Mitros+ set to Odin receiver and there is no connection between them at all. So I would say the Sony version are still highly unlikely to be compatible at all between system either.

    How can I buy it in US ?

  17. Aussieraven 5 years ago

    I’ve been reading through this and this seems like the only compatible, straight forward HSS/TTL enabled strobe for Sony system!

    In australia I don’t see it as being listed anywhere, I’d like to get some feedback or feedback from people who have tried it. I use a Sony A7r II and would love to be using strobes that can have HSS enabled. Was thinking of a Rovelight, or a godox ad360 (or gs 600) but having seen this it looks compatible. a profoto b1 doesnt support HSS with sony no matter what. I hear with a little tinkering the godox and rovelight can be shot HSS with a sony?

    but this Canonmk K4T seems straight away compatible. how’s the remote functionality? power adjustment and available mounts?

    • Author
      Flash Havoc 5 years ago

      Hi Aussieraven,

      I have the original A7 and the K4T appears to work fine in HSS mode with that. I still need to get on to the K4T review so I haven’t really studied the light with the A7, though it does appear to work ok with HSS and TTL.

      You can see in my longer comment further above there are some quirks with the FEC with Canon and Nikon, so there may well be some with Sony as well, though in general they do work.

      The transmitter is a little cheap feeling, though it works well and has plenty of buttons to access everything quickly.

      There is a slim line Bowens mount adapter available from ConnonMk for the light, and they are aware now they will need to make those available anywhere the light is selling to the western market.

      And at this point the probably will be the biggest issue, getting the light and ongoing support. ConnonMk were going to look at listing the light directly on Ebay again, though they don’t appear to have done that still. (They could well be waiting for me to get my act together and post a review first though as well).

      So you would need to contact them directly to purchase the light. If you email me through the contact page here I can get you in contact if needed.

      The HSS mode though is the automated kind like using a TTL speedlite. The Rovelight is using the long duration sync method, and the Godox Witstro and Ving do pulse the flash like a speedlite does in HSS mode, though there HSS mode needs to be turned on and off manually (and is limited to the number of shots at higher power levels).

      So basically any strobe with long enough flash durations can be used in a similar way to the Rovelight with long duration sync, using the Phottix Odin transmitter (and ODS timing adjustment). IGBT flashes like the Witstro generally need to be used at full power where there duration is longest (if you don’t use their HSS mode).

      The Jinbe HD600V and Rovelight will have their own HSS enabled transmitter coming, though I don’t know that they will produce a Sony version transmitter, so you would likely still be using the Odin to at least fire the flash anyway.

      Phottix do also plan to add Sony compatibility to the Indra 500 etc, so they may be a more accessible option once they are available (for TTL and HSS).

      The Connonmk flashes are good flashes though otherwise, and the only HSS / TTL 500ws strobe available right now for Sony.

      • Aussieraven 5 years ago

        That all sounds good to me, I’m wondering about the canonmk K4T flashes but I haven’t seen any listing for them online or a contact. Is there anyway to contact the company? or to know that it will natively achieve HSS without anymore redundancies in triggers and whatnot?

        Otherwise I might opt for the Jinbei HD 600 option, and read through exactly what I need to get to use HSS on my sony camera !

        • Author
          Flash Havoc 5 years ago

          I take it back, it looks like ConnonMK have actually listed the K4T on ebay again here.

          Though it looks like you will need to contact them again regarding the Bowen’s mount adapter and Sony transmitter with multi interface shoe.

          If you can’t get in contact with them through Ebay, let me know and I can get the sales representative to contact you.

          If you go with the Jinbei or Flashpoint lights you would need the Phottix Odin transmitter and receiver. Pixel Kings for Sony are the only other option, though they are now discontinued, so you may need to look for second hand units.

          • Aussieraven 5 years ago

            Oh the pixel king is no longer available?

            With the phottix odin/transimitter is there a specific model number i should go for to the sony? Like an adapted version for the old Mount instead of the new one (new being MUi a7/a7r….etc)

            Getting confused with all the redundencies with sony so I want to get it right at least lol

            Ive tried contacting them myself yesterday with no avail :/

  18. daemorhedron 5 years ago

    So interested in these, but very unclear as to how to order them. The link above is dead, the site appears to only be in chinese and can’t find them on ebay. Just need something cross canon and sony for at least HSS, so frustrating.
