YongNuo YN685


To set the YN-685 apart from YongNuo’s RT Radio Flash System for Canon, YongNuo have chosen to produce a completely new case design, a combination of the previous YN-568EX styling and the later YN600EX-RT, including dot matrix LCD screen and quick locking foot.

YongNuo YN685


The YN-685 provide a long awaited Radio Slave Flash for the very popular YN-622C TTL trigger system. And another alternative to YongNuo’s RT system for Canon.

One functional advantage of the YN-685 / YN-622C is the ability to control remote flash zoom length, which the RT system does not provide.

Another advantage is cross compatibility with the inexpensive YN560-TX / YN-560 III / IV Remote Manual flash system.





YongNuo YN685 Speedlites for Canon are available now from around $110 –

    How do you turn on auto zoom on the YN685 working alongside the YN622C-TX ?

    I seem to be only able to zoom if I do it manually from the flash itself and not from the YN622C-TX.

    • Simon 5 years ago

      Hi, please set YN685 into Auto zoom mode first, then you can control the zoom by YN622

    • Giorgos Tzelepis 4 years ago

      I have the same problem with Sigma 18-250 but it’s o.k with Canon 18-55

  2. Klavs Vasilevskis 5 years ago

    I purchased two YN-685c speedlites. After using them for few months, a problem occurred first with one speedlite and then with second. It showed overheating warning, and even after waiting few hours and even few days and changing different batteries I still couldn’t use it again. It was just showing blinking overheating warning when I turned speedlite on. So I sent them back.
    Has anybody else experienced similar problems?

    • Stefan 5 years ago

      yes. i have this problem me too. i send the flash back to the shop and now i waith to send me back another one. mine it was in guarantee.

  3. cory 5 years ago

    I went through a total of 6 (that’s right, SIX) of these, and I found that they were the least reliable YN product I’ve ever used. I’ve a YN user for 5+ years, and always happy with the flashes and triggers. So when these were released, I was super excited to pick them up and get rid of all my 622-C’s, but they just misfired so much and the recycle time was atrocious — overall, just lacked the same quality as the previous products, so sadly, I took them back to B&H (who were not very happy with me returning 6 flashes)

    • simon 5 years ago

      hello, cory
      Had you took them back to B&H? If not, would you show me the firmware version of YN685 which you have.

  4. Gbenga Sogbetun 5 years ago

    Hello Flash Havoc. I would have expected an update on your review of of the YN 685 for Canon. The flash is abysmally faulty. I’ve bought 4 so far, 2 of them will not do HSS, one died at an event i was at yesterday, first time i was using it, I am scared of depending on the last one which i plan to use at another event today. Yongnuo have been a really competent and reliable company but they got this one wrong.

    • cory 5 years ago

      Gbenga, my sentiments exactly! I had the exact same experience, and was also a big YN fan prior to these. Glad to know its not just me! Well, not ‘glad’, but you get the point…

      • Gbenga Sogbetun 5 years ago

        Yes I do Cory. I’m looking at the SN600C-RT with the SN-E3-RT trigger. Should be arriving tomorrow. I’ve read some good stuff about them and hope they are a true.

  5. Ephrem 5 years ago

    How can you trigger the Youngnuo 685 as a slave using my camera Nikon D7000 built-in flash.
    I tried all slave options on the flash, still not firing with my built in flash.
    Anyone has this issue?

    • simon 5 years ago

      YN685 support YONGNUO RF triger system only.

  6. Edwin 5 years ago


    I had bought a YN685 flash in April 2016.
    The HSS function on this flash doesnt function. any shutter speed faster then 1/250 the flash exposure isnt seen in the images. My canon 430 EXii function perfect with the same settings on the camera

    Is it a problem with the flash? does anyone know how to fix this? i have reset my flash couple of times.


    • simon 5 years ago

      can the flash output 1/128 power correctly? if so, i think it’s not a hw failure.
      what is the camera body you have?
      have you tried ettl and m mode in hss fire?

      • Edwin Mendes 5 years ago

        Hi Simon,
        yes the flash output 1/128 works below sync shutter speed of the camera.
        I have Canon 60D Camera body.
        I tried both, ETTL and M mode in HSS for the YN-685 flash and also my old canon EX-430 EX ii.
        Canon EX-430 ex work perfect, where as the YN-685 does fire but the flash exposure is not shown in the picture. 🙁

        Does anyone have any idea if its the flash problem or there is some settings in the camera that i need to activate? Please help.

        YN-685 flash is in warranty period, thinking of returning it back.

        Thanks in advance

  7. Chelsey 5 years ago

    Does anyone know what external battery pack I can use with the YN685? I have a Godox PB960 with the Godox cable and a Nikon cable but neither fit in the YN685 port. Thanks

  8. Gbenga Sogbetun 5 years ago

    You’re welcome Chelsey

    • peter 5 years ago

      I own a yongnuo YN685 and a Nikon SB900. Since yesterday, the proud owner of a GODOX’m PB-960.
      bought this sent a Nikon and a Canon cable (for the YN685) to do this.
      The Nikon flash fires a Flash after another. The Yongnuo seems not to work with the PB-960. Do you have an idea of what it could be?

      Thank you peter

  9. Joel 5 years ago

    I just bought yn658 along with Eneloop Pro 2450mah. I’ve just noticed that the battery indicator is not showing full bar even though i just charged my batts. Will this affect the performance and reliability of the flash?

    • Gbenga Sogbetun 5 years ago

      When i owned this flash it did the same exact thing. It never showed full bar on a fully charged set of batteries. As regards performance I don’t think it affects performance, but I really cannot say for sure because I did not own this flash for long. I wasn’t happy with the way it worked so I returned it.

    • Simon 5 years ago

      Don’t worry,it doesn’t effect any performances. The battery indicator is base on the voltage of battery,but I notice some batteries is lower than be 1.5V,even though it’s full charged. That’s why you can’t see full bar for some batteries.

    • Simon 5 years ago

      Please continue to charging one more hours,after charger status become full.

  10. Luis Kuthe 5 years ago

    I’m looking for a way to troubleshoot the overheating in a YN685. I have one that powers on and is stuck on the “Hot” error message. Wondering if there’s a reset capability, or if the flash is just not usable anymore. Let it cool, changed batteries, etc. still blinking the “Hot” error message. Thanks!

    • Klavs Vasilevskis 5 years ago

      I have already gone through three YN685 with the same problem and now waiting when it will occur with fourth one. Ordered two pieces, one stopped working, then other after a while. Then sent them away for warranty, got new one, now same problem again for one. Very disappointed. As far as I know, there isn’t any reset capability – they are not usable anymore. I assume it’s wider problem with the whole line of YN685 model, because it’s not only one case.

    • Simon 5 years ago

      Hi,would you tell me the environment temperature ?

      • Klavs Vasilevskis 5 years ago

        Normal indoors temperature – around 20 degrees C. I think environment temperature is not the issue.

        • Simon 5 years ago

          Thanks,@Luis Kuthe ,@ Klavs Vasilevskis, is it yn685c version or nikon version? If it’s canon version,please help to check whether it support firmware update or not.
          1.power off the flash.
          2.hold the mode key then power on again.
          3.if flash support firmware update, it will display yn685,version number instead of normal UI.
          4.powe off to exit update process.

          • Luis Kuthe 5 years ago

            Its Nikon version, when I tried Hold Mode+On
            says: YN685N
            Version 132
            1617 1623

            • Simon 5 years ago

              All yn685n support firmware update feature. Would you like to help make some debug things on yn685n? If so please give me your email address, I will send you a firmware in a few days.

        • simion 5 years ago

          Do you have YN622-TX ? I have a diagnose firmware for Yn685N, it can give me some information about the issue.

      • Luis Kuthe 5 years ago

        Around 22-26 C, indoors at nite. But, i have two 560IV at 1/2 power firing in a photobooth, so i think is not temperature

  11. Luis Kuthe 5 years ago

    Hi @simion i dont have YN622, i use YN560TX

  12. Vasilis Kouvalis 5 years ago

    Hi, I plan to buy a YN 685c , but as I read from your site, it seems to be problematic. Is there any solution to the problems or I should buy something else?
    Thanks ….

    • Author

      Hi Vasilis,

      Unfortunately this is nothing new for Yongnuo. They have always had a small percentage of failures and periodically gone through batches with various issues etc.

      The thing is they sell tons of these flashes, so it often sounds like these issues are more widespread than they are. So for every person complaining you’ll get at least twice as many saying they have never had an issue (so far I’m one of those, and having just about every YN flash model).

      Having said all that, no one really wants to play the gambling game, whatever the odds are. And this has seen a lot of people moving to Godox recently. I think this issue is finally catching up with YongNuo, now that there are more reliable comparable alternatives available.

      • Vasilis Kouvalis 5 years ago

        Hi, thanks for your answer
        I own a 568EXII and I haven’ t notice any problems so far. I want the 685 to pair with the 568 using the 622-tx and 622 controllers
        the camera is 5D classic
        Thank you again and I wish a Merry Xmas to you all !!!

    Does The YN865 focus assist work when the flash is off camera, triggered by i.e. YN560-TX?

    • Author
      Flash Havoc 5 years ago

      Hi Kristoffer,

      Unless I’m missing something I couldn’t get the YN-685’s AF assist light to work with either the YN560-TX or the YN-622C-TX as transmitter.

      There are 2 slave indicator LED lights above the AF assist light which you have the options of allowing to blink or not, but the AF assist light does not come on at all.

  14. Greg 5 years ago

    Hope this is not against the rules but I just listed four Yongnuo YN685 Wireless Flash Speedlite + YN-622N TX Controller for Nikon on eBay.


  15. ed 5 years ago

    Is there option to choose external battery only option in this version of flash?

  16. James Harman 4 years ago

    I have the original YN685s although the ver says 2.0.2 on the CFn page 28. I have used them for 18 months with no issue triggered via a ver 1 622C-TX trigger with my Canon 5D3.

    I recently got a Fuji X-T1 and XT-20 and if you put the 622C-TX in Legacy mode you can use the trigger and flashes or YN-622s. The YN685s fire once and lock up but the 622s work fine.
    — Anyone else having this issue?

    I bought my son (Fuji shooter) the v2 of 622C-TX and YN685s and they work fine for him except when he turns a channel off the flashes on that channel still fire.
    — Anyone else having this issue with this setup?

    Good Fuji OCF suggestions would be welcome – thanks!

  17. jim 4 years ago

    I think their 568 ex2 is their most reliable flash.No overheating or anything.

  18. Marty 4 years ago

    Any work-arounds or corrections to the YN685 flashhead being rotated 360 degrees a few times and unplugging one of the cables internally which causes it to not discharge and then cannot flash?
