YONGNUO – YN685 – Speedlite Announced!

YongNuo YN685


YongNuo have announced the YN685 Speedlite for Canon, YongNuo’s first speedlite with YN-622C compatible radio transceiver built inside.

UPDATE – YN685 are now available.

The YN685 are a fully featured on-camera ETTL flash, as well as providing Radio Slave Modes for both the YN-622C and RF-603 / YN-560 radio systems.

This means current compatible transmitter units include the YN-622C, YN-622C-TX, YN560IV Flash, YN560-TX, RF-605, RF-603 II and original RF-603,

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.


YongNuo YN685


The YN-685 provide a long awaited Radio Slave Flash alternative to YongNuo’s RT system, ideal for the many people already invested in the popular YN-622C TTL trigger system.

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.




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

    Here’s the review I posted on Amazon:

    This is a “clone” of the Canon 600EX-RT only in shape and user interface, at less than 1/4 the price. Do not expect it to be functionally equivalent in at least the following areas: Note, this review is based on having ordered and returned TWO (2) of these through different channels. Both units behaved exactly the same.

    1) The zoom motor is LOUD. On the Canon flash it is barely audible, but the Yongnuo makes a high-pitched whirring sound that can last as long as 1/2 second.

    2) The focus-assist beam consists of a matrix of very thin laser-drawn crossed lines, in contrast with Canon’s wide alternating black/red bars. The result is that unless the crosses line up with the focus points you may not get any focus assist. Due to parallax it’s actually quite hard to get them to match up except at specific distances. This is compounded by the fact that the hotshoe mount has some wiggle room so the focus assist beam will move from shot to shot as you move the camera. The Canon flash has no play in the hotshoe mount, but that’s immaterial anyway because the Canon focus assist beam is a much better target for the AF system. Not sure what Yongnuo engineers were thinking here.

    3) The flash underexposes severely in bounce mode with longer focal lengths. See http://photo.stackexchange.com/q/73399/492 for a detailed analysis. This seems to be a known problem that has a workaround: set the camera’s metering mode to “average” instead of “evaluative”.

    If your usage is primarily direct (non-bounce) flash in situations where you have enough light to focus and some audible noise is not a problem, then this could be a really inexpensive alternative to Canon’s flagship speedlite. For me as an event photographer it will not work. I did not evaluate any of the radio remote capabilities as I do not need them.

      Not really a 600EX-RT clone (that would be the YN600EX-RT) as much as a 580EX II clone without optical master/slave capabilities and a YN-622C receiver instead.

      Thank you very much Jim Garrison. Your test review has been very helpful. Now I know why my unit underexposed on me on my last few shoots.

  2. Jamesy 6 years ago

    @Jim Garrison: Excellent review – thanks for sharing.

    As I use primarily to light a background in manual mode I had not encountered the areas you reviewed. The zoom is a tad noisy for sure compared to my 580EXII’s. I have used them for roughly 1500 shots with the 622TX as the wireless controller and the YN685’s have been rock solid.

  3. John Yakubik 6 years ago

    I have purchased two of these because I already had the 622C transmitters. After reading your post I tested with the same results. It will bounce expose properly if #1 I use flash exposure lock first or #2 I switch it from evaluative to average. If it is in evaluative mode it exposes properly at wide angles and underexposes at longer focal lengths when bouncing off my ceiling. I have not tested off camera yet but it seems that on camera is the only place people are experiencing this issue now. I also agree that the locking mechanism is a little loose but it hasn’t caused mine to misfire.

  4. i have a problem with my yn685 on my camera 5ds, sometimes i have overexposed for +3 or more when conected on yn622 triger,anybody have same problem?

    • frank Garvock 5 years ago

      Me too. caused embarrassment at a photoshoot as had to do the same. Going to bin it. I have a 5D mkII BTW

  5. udi 6 years ago

    I didn’t understand if this flash unit works as a master radio if it’s on the camera?
    I have lots of 560 III and i’m working withe the rf 603 II off the camera hot shoe.
    can this flash replace my master unit and release me from weirs?

      Hi udi,

      No the YN685 do not have a radio master mode.

      The flashes you would need with radio master mode to the YN560 III are either the YN660, or YN560 IV

      If you want a transmitter unit with a the flash, you can use the YN560-TX.

  6. Mike 6 years ago

    I have the YN685 Speedlight and the YN560TX Manual Flash Controller. I am not able to make the controller trigger the flash? Any ideas on how to synch them to make them work?

      Hi Mike,

      Do you have the YN560-TX set to RF603 mode?, it should display RF603 on the screen when switched on.

      The flash then needs to be set to one of the RF603 modes in custom function 24.

      Obviously they need to be set on the same channel and group.

    After having 4 YN-560 III and having absolutely no problems with them, I just bought a YN-685 a few weeks ago.

    Yesterday I was using it for a shooting the first time. I shot an event and after about 1 hour and about 75 images my AF Assist Light suddenly stopped working. The flash itself still worked but focusing was completely impossible. Luckily the event was almost over so I didn’t miss much but of course my client wasn’t amused and I was pissed of severely.

    Has anybody experienced something similar? I already contacted support but they keep asking me silly questions like “Are your batteries empty?” (while the flash still fires like a supernova…).

    I bought this flash because I need it for some shots in the near future and now I’m facing the nightmare of having to send it back in (to HongKong) and wait weeks or months until I (hopefully) get a replacement…

    Damn it, was so happy with Yongnuo until yesterday but this is killing me 🙁

    • simon 5 years ago

      AF light can be disable in FN setting. could you check it in the FN setting?

  8. Marcus 5 years ago

    After talking to the support guys in China for a week without getting any useful help, I almost sent it back when I went to the post office to grab my replacement flash from another vendor. Luckily I was in a hurry and didn’t do it. Because when I got the new flash this one also didn’t work so I thought it must be a problem with my camera.

    And after fumbling around for another while I finally found the solution: It’s my focus mode. At some point, I had switched it to “AI Servo” and in that mode the AF assist light just doesn’t work. That’s it.

    On the one hand, I’m really happy that my flash is ok and I don’t need to send it away. But on the other hand, I really ask myself why this limitation isn’t mentioned anywhere (at least I didn’t read it) and why the “support” guys from Yongnuo didn’t tell me…

    Hello from Germany.

    I’m not sure whether I am wrong or that the system does not work.

    Is the yn622c-tx be able to trigger a yn 685 n?

      Hi Matthias,

      Sorry no, the YongNuo Canon and Nikon TTL systems are separate systems, they can not trigger each other.

  10. Vaid 5 years ago

    Can anyone tell me if this flash will work with the new Canon 80D. My Nissin Di866 MKII which worked fine with my 550D is not compatible with the 80D. So don’t want to invest in this only to find its also not compatible.

    • K 5 years ago

      Anyone else having problems with yn685 menu problems and af assist not working on their 80d?

  11. DIMITRIS 5 years ago

    I have for a same time now, yungnuo yn685 and i notice that its much slower than yn560 III. Its normal? I use them both as slave manual mode 1/16 and yungnuo yn685 miss much shoots.

    • Simon 5 years ago

      could you tell me what is the firmware version of your YN685? It’s recommend to use SANYO ENELOOP battery.

  12. kfir 5 years ago


    just received my yn685 and now found out it only works as slave 🙁
    is there a way i can place the 685 on the camera, and with a cable trigger the yn560tx, so that he will trigger the other units?
