YONGNUO – YN660 Speedlite Announced

YongNuo YN660


YongNuo have announced the YN660 speedlite, being the latest evolution in the very popular YN-560 range of manual speedlites, with recent models providing 2.4GHz remote manual radio transceivers built inside.

The YN660 build upon the previous YN560 IV, now providing 6 groups in the Radio Master mode, up from just 3 previously.

As well as boosting power output to a Guide Number of 66 meters (ISO 100, 200mm), which should now bring the YN660 fairly close to matching the top end Canon and Nikon Speedlites for output.

Other improvements include 20-200mm flash head zoom, lever locking foot, and updated buttons / main control dial.

YongNuo YN660


The YN660 are basic manual only speedlites when used on camera. Though their main features / functions are the remote manual Radio Master and Slave modes.


Compatible slave flash / receiver units include –


Compatible transmitter / master flash units include –

With the YN560-TX tranmitter, and YN560 IV / YN660 flashes providing the most functionality, including Remote Manual Power and Flash Head Zoom Control.


Unfortunately the YN660 still do not provide a Radio Slave mode compatible with the YN-622 systems for Canon or Nikon.

For that you will need to look at the more advanced YN685 Speedlites (available for Canon at least at this stage).

YongNuo YN660


The YN660 provide an HV Battery Port (Canon style) for attaching external high voltage battery packs, as well as a basic PC Sync Port.

(Though unfortunately still no USB port for firmware updates).


YongNuo YN660


Being a single firing pin speedlite the YN660 are universal for use on any camera, though they provide only manual power levels when used directly on the camera hotshoe (no TTL or HSS etc).

YongNuo – YN560 IV Overview

YongNuo – YN-560 III Full Review

  2. Nevel 6 years ago

    Still no damn hss.

    So basically a new 560 body a bit more power and wider zoom range.

    Where dahell is the nikon 568mk2 and a nikon rt unit?

    I do like my shanny sn600n which i use as ocf. but damn that crap dial/flash buttons/crap display with tiny readout. Thats what i love about my 560III the big readout of numbers.

      Hi Nevel,

      It doesn’t really make much sense to have HSS with the YN660 flashes unless they were to be compatible with HSS enabled radio triggers like the YN-622.

      At this stage YongNuo are still avoiding compatibility with a cheaper remote manual YN560 / YN660 flash and the YN-622 system. You have to go with the YN685.

      I’m really not sure why YongNuo have neglected the Nikon system though, even the YN-622N could use some refinement still.

      At this stage though I would imagine they would be working towards a master and slave version of the YN685 (needed for both Canon and Nikon). The YN685 have already superseded the YN-568EX to a large degree, so I’m guessing its probably unlikely YongNuo would would be too concerned with a YN-568EX II for Nikon at this stage.

      • Jeremiah 6 years ago

        I am so frustrated by this. I recently bought a pair of 622v2s to try and trigger my 560III/IV’s and there was too much of a delay time between the radio signals for it to work effectively. I returned them and wrote to YN letting them know about the ongoing issue.

        I find it hard to believe that there is a “language barrier” between the systems that can’t be overcome when they have a 622 able to be triggered by the 603 system. If it can be triggered, it shouldn’t be a large jump to allow it to transmit as well. I’ve modded several of my 603’s to allow them to trigger through the PC sync port as they don’t have TTL pass through. If they included this as a feature, problem solved.

        Either way, something has to give. I am tired of PC synching them or not having them allow compatibility with a TTL passthrough system. I am too invested in gear to switch to all TTL, though that would be logical step. For the amount I shoot with them now, I don’t want to re-create my whole kit with 568’s or their next iteration of TTL/HSS/2nd curtain compatible flashes. I wish the 560’s did that but for the money, I am happy with them.

  3. Ron 6 years ago

    So they claim a higher guide number but it is at a longer focal length (200 mm). Is it actually more usable power or is it the same power focused into a smaller a angular area?

      Flash Havoc 6 years ago

      Hi Ron,

      YongNuo claim a guide number of 60 at 200mm with flashes like the YN600EX-RT. They are making a point of the fact that the YN660 are higher power.

      The YongNuo flashes are generally around 1/3rd of a stop less than the Canon 600EX-RT and Nikon SB910 though, so they YN660 should be pretty similar now.

  4. Michael 6 years ago

    Still no focus assist – couldn’t care less… 🙁

      Flash Havoc 6 years ago

      Guys, focus assist and HSS require the full TTL pins and dedication to particular camera makes.

      If you want those features the YN685 are the way to go (available for Canon at least at this stage).

      • Michael 6 years ago

        True, except the fact that the YN685 will not trigger other YN560III units.
        I’m on my way to shoot another wedding, with 3 off-camera YN560III units. Also need a unit on my camera, that has a focus assist light. Yongnuo does not provide any on-camera speedlight capable of doing all of the above, unfortunately…

        • Author
          Flash Havoc 6 years ago

          Hi Michael,

          When I first saw the YN660 I though it was highly likely it would actually be a remote manual version of the YN685, and compatible with the YN-622C etc.

          Unfortunately that’s still not the case, and it appears YongNuo have not changed their attitude to providing cheaper remote manual flashes (like the YN-560 III / IV) compatible with the 622 and TTL systems.

          So if you want any of the advanced feature (TTL, HSS, AF assist etc) on or off camera, then you still need to look towards the YN-622 / YN685 system (and basically forget about combining the YN-560 III).

          YongNuo don’t have a Master and Slave version of the YN685 yet, though its inevitable those will come eventually. So the system you will need to work towards now would be that master / slave flash when its available, and YN685 as the slave flashes.

          At least the YN685 will currently work as slave flashes to the YN560-TX and YN560 IV etc (in place of your YN560 III slave flashes).

          • Michael 6 years ago

            IMHO using the YN685 as a slave unit is an overkill – all I need is a simple manual remote controlled unit, and the YN560III fits the bill. YN560IV is very good in what it does, except it lacks the focus assist light, which is so necessary for shooting weddings (or other dark environmetnts). All other fancy functionality is completely redundant for this scenario.
            I know quite a few wedding photographers looking for this simple solution, and would buy such an on-camera unit in a heartbeat (YN560V would be a natural name for it… 🙂 ).
            Pity that marketing departments at various companies come up with tons of dumb functions, that nobody uses (stroboscopic flash sequence is one of those redundant functions), yet somehow they fail to deliver the basic system, that would work for many working (and amateur) photographers.

            • Author
              Flash Havoc 6 years ago

              I think YongNuo are well aware of the issue, and hopefully they may come up with a more advanced master flash to the YN-560 system eventually.

              That would need to be full TTL, HSS, SCS, etc on camera though, as there is no point having a heap of different flash models with just one feature to suit each persons needs. You don’t have to use the TTL etc if you don’t need it. I don’t think there are any manual radio triggers with an AF assist light because that is usually combined with the whole TTL communication.

              If the master and slave version of the YN685 were to follow the same pattern as the original YN685 then that could be the flash to offer a 560-TX master mode (as well as the YN-622 master mode).

              Unfortunately though if everything we have seen so far is anything to go on YongNuo are going to resist providing any master function from the YN-622 capable master / transmitters. I hope this does change eventually though I’m not counting on it.

              Integration between the YN-622 and YN-560 is by far the most requested thing I hear about though. For the same reason, people are often happy with their 560 slave flashes in the most part, though still need the extra functionality on camera (AF assist, TTL etc at times).

              YongNuo made the mistake though in my opinion of aligning the YN-560 III with the RF-603 system instead of the YN-622. There were obviously good practical reasons for doing that, but the long term consequences are the difficult disjointed systems we have now. I don’t think there is any doubt YongNuo would sell far more gear if it all worked together nicely, and people could buy what the needed knowing its all going to work together.

              I even tried to get this across to Shanny (founded by a former YongNuo engineer) who have the big advantage of hindsight and a clean page to work with, though even they would still not listen.

              • Michael 6 years ago

                Maybe you could design and kickstart a proper speedlight system, and raise money from the community for this project. Nobody knows speedlights and photographers needs better than you, and I am confident you would easily raise the required funds from the many readers of this forum – I know I would participate!! 🙂

          The YN 568EXII actually does have focus assist beam and hi-speed sync

  5. Niels Gram 6 years ago

    I bought a 560TX and two 560III some time ago hoping that they would work well for me. Unfortunately it turned out that the build-in trigger receiver in the 560III isn’t able to follow the 10 fps frame rate of my camera. Using an external receiver (Pixel King X or YNE3-RX) allow the flash to follow the camera. Compared to my Canon flashes (580II and 600EX-RT) the 560III lacks power and the 560TX is unable to do 2nd curtain sync which is a feature I need (the 560TX is already Canon-specific so why not support 2nd curtain sync as well…). I hope the YN660 will solve the frame rate issue of the trigger receiver in which case I may be interested…

    • H.J. Karbach 6 years ago

      … the 560TX is unable to do 2nd curtain sync which is a feature I need (the 560TX is already Canon-specific so why not support 2nd curtain sync as well…). …

      I can’t agree with you. I tested it with my Nikon Dx2, YN560TX (N) and YN560IV and it works fine. The only different setup to do, was to tell the camera triggering on 2nd curtain. Thats all.

      Yes, there are two versions of the YN560TX. Canon and Nikon. But they differ only by the way how to wake up the YN560III, YN560IV. And I don’t think YN changed this for the YN660.
      So it should work even your on-camera-YN560III flash does.

      If I had two free a wishes according to the YN560TX, it will be a FreeMask-Function*
      and a USB-connector for firmware updates.
      While the wish second should be self-explanatory, let me state the necessary changes and settings.
      All YN has to do, is to implement a mode to the TX that toggles between flash-groups
      i.e. F(oreground) and B(ackground) after every trigger comming fom camera.
      That should be all for 560TX!

      The camera must be configured to “continued release”, conviniently restricted to 2 releases per one push at the cameras release button, if possible.

      So it would be possible to shoot
      – first the person or object in the foreground triggering F-grouped flashes** and
      – second lighting the background triggering the B-group flashes**
      Disolve moving objects is only restricted by the framerate of the camera.

      Sweet dreams! Hmm! 🙂

      * Short explanation here: https://www.youtube.com/watch?v=UyfmAAfuf3o
      ** Or YN RF605. To trigger older flashes, or studio-flashes, Portas etc.

      • Niels Gram 6 years ago

        Well, as a Nikon shooter you have an advantage for 2nd curtain sync since it is controlled entirely from the camera. Not so on Canon – for Canon 2nd curtain sync is a flash-feature so the 560TX can’t do 2nd curtain sync on Canon.

  6. Niels Gram 6 years ago

    By the way: Looking forward to the YN660EX-RT 😉

  7. Jacques Cornell 6 years ago

    Y’know, if they’d just put in an autothyristor mode for auto on-camera and manual off-camera, a lot of non-CaNikon event shooters would be ecstatic.

    • robert 6 years ago

      You are so right!!! I want a YN560III or YN660 with the choice of Thyristor auto like the old 283/285’s. A decent Thyristor auto would solve a lot of non Canon or Nikon users. I would like an economical auto flash, NOT TTL, for my Panasonics.

      Hi Emanuele,

      No the YN660 are not compatible with the YN-622 system as transmitter.

      If you’re using Canon, then the flash you would need is the YN685.

      I don’t know when the Nikon version of the YN685 will be available unfortunately.

  10. Marcello 6 years ago

    I wonder when Yong will provide hardware for their YN-560 old line up. I inested into it hoping an all-in-one trigger will come out one day, instead we got all sorts of triggers with limitations…

    I would rather see my YN-560-III work properly then invest into another flash with shady hardware options.

  11. H.J. Karbach 6 years ago

    Hi, Flash Havoc

    Regarding the photos, I found a bunch of changes I am confused about.

    Do you have any suggestions about the third connector on the left side?
    The upper left ist the canonstyle 3-Pin HV-supply connector.
    The minor round one might be the PC-Plug.
    But what might be the upper right connector for?

    And what are the notches at the bottom side of the flash head for?
    A proprietary mount for accessory equipment, such as the former Metz 45 with a feeler pin to control the zoom reflector position if mounted a diffusor or a Fresnel-Tele attachment?
    Also interesting they changed the locking mechanism of the battery compartment lid.
    No longer sliding the whole lid. Okay, but i never had any problems.

    At least, YN changed the directional pad against a common wheel control. Besides, the directional pad is liked very much, because you can change the strength of the flash with one finger, even if the display cannot be seen while working over head.
    Fortunately does not affect me. I use a 560TX.

  12. Niels Gram 6 years ago

    Both design features come directly from Canon flashes. The thread on the left side is for a flash bracket.

  13. Looks good

  14. Mariosch 5 years ago

    So, apparently the YN 660 seems to be available, at least I’ve seen ebay listings with shipment from Germany only a few bucks above the YN 560-IV, so it doesn’t seem to be a pre-order listing…

    Can anyone confirm availability or maybe anyone already own one and can say something about built quality and functionality?

  15. kcvb 5 years ago

    Dear flashhavoc

    i would like to ask you two questions.

    1. Do have any other flash with better feature than this at similar price?

    2. How to keep camera safety when we stop use? Because my camera now is broken. Rubber around camera is broken. Maybe inside have rubber will broken soon. Becuase i keep in mirror box. No air for long time it broken like this.
    If keep it ouside dust alot. Afraid dust to sensor. How do we keep it safe and no problem?

  16. Robert T. Johnson 5 years ago

    It looked so promising and then no HSS, it’s a deal breaker for me. When shooting at f1.8 or f2.8 you will need HSS in your speedlight, currently a Shanny users and looking for other options, but require HSS.

  17. kcvb 5 years ago

    Robert T-johnson

    what u mean? Does shanny have HSS? Which one with radio transmitter and hss with low cost like this yn 660?

  18. Peter Kim 5 years ago

    I bought one of these units and the mode and other buttons do not light up, although I have seen videos of the unit where they do light up. The seller claims YN manufactured TWO versions: an earlier version with unlit buttons and a later version with lit buttons. Sounds fishy to me, but if anyone has info on this it would be greatly appreciated.

    • Author
      Flash Havoc 5 years ago

      Hi Peter,

      I’m not sure about that. The buttons light up on the YN685 I have, which are basically the same flash body.

      Probably best to see if you can get an answer from YongNuo directly.

  19. Leonardo 5 years ago

    Hello. So, I have 02 YN 865 and one YN 622C-TX. What I want is a flash that I can put on my camera and still control the power and zoom of my two YN685. Im not able to put a flash on the top of my YN622-TX. Can the 600 do that?

  20. RichardV 5 years ago

    Hi all…..I have recently purchased the YN660 manual flash, and now after only a few weeks, the “single-pin” of the flash is somehow not communicating any signal whatsoever to my Canon digital Rebel XS, which is an acceptable camera for proper operation. To check further, I mounted the flash to my Canon EOS A2 film camera, and it would not fire from the hot-shoe, but would operate with a sync cord. Hmmmm.
    Unmounted , as if used for off camera operation, the flash fires perfectly in all modes and power levels. So now I’m scratching my head trying to figure this out: Is it the cameras hot shoe that has failed, OR is it the pin of my new flash that isn’t communicating to the camera??? Arrrrrrrrrggggghhhhh!!!! Help!

  21. RichardV 5 years ago

    I bought the YN660 around mid December and sent it back to the seller via Amazon today…(12/27/16) It lasted about a week and a half. Now I must say that when removed from the camera hot shoe it worked great, firing in all modes and power levels. Once mounted to the camera, nothing. I agree with other folks’ comments about the single pin not communicating with the camera. Nonetheless it’s still frustrating, and I do not believe it should be happening as often as I have read, on other review sites, blogs, etc.
    Maybe it’s something simple to fix, but that’s not the point. I tried every which way but loose to try and get this unit to fire from the camera, and no go. I tried new batteries, mounting on different cameras, tried it connected off-camera via cable and connectors…still nothing. I don’t know how Yongnuo can continue to get four stars or more on their product ratings with these kinds of issues cropping up as often as they do. That will likely change as more and more units are returned to the sellers.

  22. Michael Deaton 5 years ago

    I see some people asking about focus assist beam. The 685 isn’t the only Yongnuo that has it. The YN 568EXII actually does have focus assist beam and hi-speed sync
