YN-E3-RT – Adds Remote Manual for NON Canon Cameras!

The new YongNuo YN-E3-RT transmitter has only just started reaching customers hands, and already another significant improvement has been added over the original Canon transmitter through the latest V1.07. firmware update.

This update now adds the ability for the transmitter to fire when mounted on non Canon cameras, and with remote manual power control of the 600EX-RT slave flashes still available. You simply need to press the test button to transfer the M mode power setting to the flash.

[ Note – This is remote manual only though, no TTL function on non Canon cameras. ]


YongNuo YN-E3-RT


By far one of the most common questions asked now is which triggers will work with non Canon/Nikon mirrorless cameras, as well as having full function on Canon etc DSLR’s. This is because many people now (including many professionals) are choosing to use both DSLR’s and mirrorless cameras, for their respective advantages.

Many TTL triggers simply won’t fire if they are not connected to a dedicated DSLR with full TTL contacts on the camera hotshoe. Which is also the case with the original Canon ST-E3-RT transmitter. This is a little bit ironic, because you can actually hold the transmitter in hand (not connected to any camera) and not only remotely change manual power levels on the slave flashes, but fire them with the test fire button as well.

With the new V1.07 firmware update the YN-E3-RT can now be use with non canon cameras (provided they have standard iso hot shoe). You simply need to press the test button to transfer the M mode power setting to the flash.


YongNuo YN-E3-RT


This added ability to work with remote manual power control on non Canon cameras adds to the list of  features the YN-E3-RT transmitter now includes over the original Canon ST-E3-RT –

  • Full Group Mode with pre-2012 cameras
  • Fires with Remote Manual Power Control on non Canon cameras
  • Second curtain sync (in manual only)
  • AF Focus Assist Light
  • Slave flash charge status does not stop other flashes from firing
  • USB port for firmware updates


V1.07 is available now available through links at the bottom of the page here – http://www.hkyongnuo.com/e-detail.php?ID=337


Firmware Version 1.07:

Fixed: When one of the group is set to ETTL mode, if one of the flash is not
recycled, it may make a full output flash due to incorrect light metering. Now
YN-E3-RT won’t trigger a flash in such a situation. Note: if the group is set
to M mode, a flash will be triggered no matter it is recycled or not.

Fixed: improved flash syncing with cameras after 2012.

Added: Legacy flash trigger (for non canon cameras). Now you can use YN-E3-RT
on non canon cameras with standard iso hot shoe. You need to press test the
test button to transfer the M mode parameters.


So this is quite a significant development for the many people now that would like to use mirrorless as well as their Canon DSLR’s. And really opens the Canon RT system up a step further (which Canon would no never do themselves, and are no doubt not thrilled about).

    Having a heck of a time updating the firmware. It’s hard to be a paying beta tester with a Mac in a Windows world.

  2. Meddin Studios 8 years ago

    Can you build groups entirely off the Tx or do you have to set the respective group on the flash head itself first?

    • Author
      Flash Havoc 8 years ago

      Hi Meddin,

      You would still need to set each flash to a particular group directly on the flash first.

      I’ve never really thought about assigning groups through a transmitter. That’s an interesting concept, which could certainty be handy of you can’t access the flashes at all. It could possibly get confusing though too I think.

    Quote from above article:

    … “as well as having full function (TTL, HSS etc) on Canon or Nikon DSLR’s”

    I was not aware this unit worked on Nikon DSLRs with full TTL function.

    Is this an error in the update report??

    • Author
      Flash Havoc 8 years ago

      Hi Photomy,

      That quote was just referring to radio triggers in general, not the YN-E3-RT specifically. I don’t think there are any TTL triggers (other than the optic to radio bridge Radiopopper style triggers) that will work with both Canon and Nikon in TTL.

      By far one of the most common questions asked now is which triggers will work with non Canon/Nikon mirrorless cameras, as well as having full function (TTL, HSS etc) on Canon or Nikon DSLR’s.

      • Mike 8 years ago

        So are you saying that the trigger with the new firmware now work on Nikon cameras like it would on other non-Canon cameras.

    So, I’ve loaded up Windows 7 SP1 on my 2013 macbook air via bootcamp, go to load the driver for the YN-E3-RT firmware update tool – driver fails to load or says no drivers were found for the system. The firmware updater runs fine, just can’t see the unit without the driver. Anyone else? Suggestions? I’d hate to have to buy a PC just for this…

    • Jeff Hamm 8 years ago


      I had same issue. Run the device driver for either 32bit (x86) or 64 bit in the the Drivers folder of the updater- they are exe files. The exe will install the drivers into Windows. Then power up YN-E3-RT in Firmware update mode ( Hold down MODE and flick power switch on), plug it into computer and find new hardware pops up and will then find the Device driver on your computer. After Windows finishes installing new device, power the YN-E3-RT off and then run update program. When you turn on the YN-E3-RT (in Firmware update mode), the program with display that it is detected.

    Success! I downloaded the driver installer from blog YN622.RU (http://www.yn622.ru/2013/12/yn-e3-rt_14.html) and it installed fine. Wonder why the installer direct form Yongnuo is jacked?

      It works well.
      Probably what you make it a mistake.

  6. pedant 8 years ago

    just fyi, running the updater in a virtual machine (VM) did not work for me.
    had to dig up an old windows xp laptop to successfully update the firmware.
    used the files from the official http://www.hkyongnuo.com/e-detail.php?ID=337 page

    details of the failed vm update attempt:
    Tried to update the firmware to v1.05, but the updater program (which is for Windows only) gave me error code 130. It detected the device (i set up VirtualBox to catch the usb device), but when I hit “Update”, it threw that error code. It didn’t mess up the device or anything, it just refused to update. Used Win7 x64 running in VirtualBox (with the extension pack installed (for better usb support)) on OS X.

    it’s also worth noting that before i got it to work by using an actual windows machine instead of a vm, i emailed their tech support (service@hkyongnuo.com) but never got a response… not cool.

    good product though 🙂

  7. ksporry 8 years ago

    good to know I need a Windows machine…

    Now, if Yongnuo ever were to make strobes with a build in transceiver compatible the YN-E3-RT, they would give some studio strobe manufacturers a serious run for their money!

    Aloha from Hawaii!

    Simple question: I use a Panasonic GH3 mirrorless camera, and I have 3 Yongnuo YN560-III manual flash units. Will the YN-E3-RT trigger these units from my GH3???

      Hi Jeff,

      Sorry no, you want the RF-603 II for now.

      Once the YN-560 transmitter is available (eventually) that should work on non Canon/Nikon cameras as well. Thanks.

  9. Beciuz 8 years ago

    I have a Canon 650d and a 600EX-RT. I just ordered the YN-E3-RT that i’m waiting to arrive .
    How can i radio trigger a manual flash (YN-560, V850 o similar) at the same time using the YN-E3-RT to trigger the canon 600EX-RT in ttl? Is it possible to use the a YN-622C, with a TTL Pass Through Hotshoe, as a radio trigger for the manual flash, and use the YN-E3-RT upon the 622c, to trigger the 600EX-RT in ttl?

    • Author
      Flash Havoc 8 years ago

      Hi Beciuz,

      Since the 650D does not have a PC sync port, the best option would be to use Phottix Strato II on the camera hotshoe, and place the YN-E3-RT on top of the Strato II hotshoe.

      You would then need Strato II receivers on all your manual flashes. Or you could possibly put the Godox or YN transmitter on top of one Strato II receiver, and use the built in receivers in the manual flashes V850/YN-560 III. That would cost some sync speed though.

      Calumet have the original Strato for just $40 the set at the moment, which is a bargain. They don’t have a group function though.

      I would have to test the YN-E3-RT on top of the YN-622C, but I really can’t see that working, not in TTL anyway. And likely not in manual either. They are 2 TTL transmitters both trying to act like a flash on the camera hotshoe, the camera just wouldn’t be able to deal with both at the same time.

      I was asked to test the Pixel King Pro last week in a similar fashion, and remote manual would actually work with the YN-E3-RT on top. With HSS as well. But no ETTL, and no GR group mode either. They would both make the system go haywire.

      I doubt the YN-622C would even get as far as remote manual working on top though (as the King Pro do not operate through the camera menu as the YN-622C and YN-E3-RT are both trying to do at the same time). Thanks.

      • Beciuz 8 years ago

        Thank you for your precious answer, giving me a solution to a difficult question for me.
        By the way, aftewords, I think that the upcoming Yongnuo integrated systems, and hopefully a coming compatible RT reciever for this particular pourpose, will be another possible and arguably more easy solution to this question. At this time, i think that I should wait and see what Yongnuo is going to show next, at least till i recieve the YN-E3-RT I ordered.

        • Author
          Flash Havoc 8 years ago

          Hi Beciuz,

          No worries, I will test the YN-E3-RT on the YN-622C pass through later and get back on this.

          Yes an RT receiver would be very helpful. I don’t think we will find out much about whether that is going to happen though for a while, likely not until YongNuo release the studio light solution (which may not necessarily include a separate receiver).

          I would be surprised if they do not at least make a separate manual receiver at a some stage though. Thanks.

            Thank You…Flash Havoc….
            So far I have another doubt about the Minolta/Sony flash socket mount….Can I use the YN-E3-RT with an old Sony A100 through a Sony-Canon Flash adapter like the Kaavie TF-325 or anything else similarly cheap?

          • Author
            Flash Havoc 8 years ago

            Hi Beciuz,

            That should work, but you may still need to block the TTL contacts on the hotshoe adapter.

            You could possibly take the adapter apart and cut the wires, or remove the contacts in the foot for all but the main firing pin.

            Or simply tape over the TTL contacts on the top of the adapter foot. Thanks.

    I’m seeing no reference anywhere on Yongnuo websites (either one of them), that this tranmitter works with Nikon.

    So I’m confused. This article is clearly stating that I should now be able to use yn-e3-rt with my Nikon camera as a TTL trigger. So why is there no such information on the manufacturer’s website?

    When I wrote support, they also confirmed that no such Nikon RT exists yet.

    what’s the deal?

      Hi Gene,

      I’m seeing no reference to that on this site either, so I’m not sure what the deal is?


      This update now adds the ability for the transmitter to fire when mounted on non Canon cameras, and with remote manual power control of the 600EX-RT slave flashes still available. You simply need to press the test button to transfer the M mode power setting to the flash.

      I’m not claiming any TTL with Nikon cameras, just remote manual. Thanks.

    Even with FW 1.08 the Remote Shooting Mode still has a bug for pre 2012 cameras. When used it doesn’t fire the remote flashes, the Canon ST does, as does the YN with post 2012 cameras.

    • Author
      Flash Havoc 8 years ago

      Ok thanks for that Privatebydesign.

      Could you please contact YongNuo with this as they would prefer you contact them directly so they can work through the issue if possible, and instead of myself opening a ton of support cases – service@hkyongnuo.com Thanks.

      (I only have one 600EX-RT here right now as well so I have borrow more to experiment with this).

      • Privatebydesign 8 years ago

        I did that, but I think my meaning is being lost in translation. They say it is by design and even post 2012 cameras behave the same, which would be fine, but for the fact that it is not true. For a fact the 5D MkIII, 6D, and EOS-M all fire the flashes in Remote Shooting Mode, just like the Canon ST-E3-RT does. The YN-E3-RT works differently for post and pre 2012 cameras, the ST-E3-RT does not.

        It is not a biggie, but it does mean I can’t sell my ST-E3-RT.

    Anyone tried the trigger with Fuji X-E2 and/or X100s?

    When I have the trigger mounted into the hot shoe of either camera, and press the Gr button to change power ratings for any connected flashes, the screen sort of flickers and won’t let me change any power settings on any flash. If I remove the trigger, change the settings, and then put it back on the hot shoe, and then press the test button, it works. But it would be better if I could change the settings while the trigger is in the shoe.

      Flash Havoc 8 years ago

      Hi denton,

      Some people have had issues with some of the Fuji cameras. The solution is to block the TTL contacts on the camera hotshoe. A single pin hotshoe adapter something like this should do the trick. Thanks.

  14. Rob 8 years ago

    Quick Question Gentlemen:

    I use an a77 and have many YN560ii. It does not look like this flash would use TTL through the camera, and thats ok.

    Which flash are compatible with this trigger? Are there any receivers that I could add to my YN560ii so get the remote manual feature?



    • Author
      Flash Havoc 8 years ago

      Hi Rob,

      Sorry, no there is no remote manual, or any remote features built into the YN-560 II unfortunately.

      A basic manual trigger to simply fire the flash off camera would be the RF-603 II. But most any manual radio trigger would fire them, and Phottix Strato II are a pretty nice mid range option there.

      The YongNuo YN-560 III flash units, do actually have remote manual control built into the flash. Though that remote power control can still not be used until YongNuo release a dedicated transmitter unit which will enable that function. We don’t know when that will be available though.

      A remote manual flash available right now is the new Godox V850. And that’s a really a nice, and relatively inexpensive option. Thanks.

    Hi Flash Havoc! Thank you to write so interesting review!, I have a doubt, can YN-E3-RT or YN-622 works on Sony Alpha A65? I would like to use High sync 1/500 or more. I want try with my FalconEyes SG100bk flash unit. thank you!

    • Author
      Flash Havoc 8 years ago

      Hi Manuel,

      Sorry no, High Speed Sync will not work unless you have a dedicated Sony compatible TTL trigger. If the Phottix Odin, or possibly Pixel King for sony are compatible with your A65 with HSS then they may work.

      There are no Sony HSS compatible triggers from YongNuo at this stage sorry.

  16. Privatebydesign 8 years ago

    So after using my YN-E3-RT in a pro environment for a few weeks I have to say, it sucks. Mine has been unreliable, with regular loss of communication, remote misfires, and very touchy menu interface that only happens when the thing is mounted on a camera.

    I now have to take it off camera to make any adjustments to remote or menu settings, once the thing drops a flash you have to go very close to reconnect.

    The thing is a frustration, when it works it is fantastic, especially on pre 2012 bodies, when it doesn’t, I just want to throw it away. It is not in the same league f reliability as the Canon ST-E3-RT that I aso own.

    • Author
      Flash Havoc 8 years ago

      Hi Privatebydesign,

      Thanks for the feedback, and sorry to hear that.

      I pretty much suspected this may be the case at least to some degree.

      But where this system may still have big advantages for professional use is for extra RT compatible flash units. They should hold up better as receivers than the more critical transmitter, and for 1/2 or 1/3 of the price they would make good spare/extra units.

      YongNuo may well improve the transmitter over time too though.

      • Privatebydesign 8 years ago

        I think it is practically impossible for third parties to successfully reverse engineer this kind of protocol, the issues seem to be that Canon keeps changing the way their cameras work, which is fine, but it means third parties really need to test with every camera body in every shooting situation.

        For instance, I mainly use 1Ds MkIII’s with WFT-E2 transmitters, I know for a fact Yongnuo don’t have a 1Ds MkIII to test with (they told me) let alone a WFT.

        As for Yongnuo coming along with high powered RT compatible hybrid hot shoe/studio style flashes, so what? If you can’t trigger them reliably they are worse than useless, and the RT system is a two way protocol, every receiver also transmits.

        Don’t get me wrong, I am not overly down on the YN-E3-RT, or Yongnuo, but I won’t invest serious money in any of their gear, the YN-E3-RT is a fun toy that could make some sense for many at the price point if they ever release that YN-600-RT and bring RT entry costs down some, I’ll keep mine as a backup or a remote camera trigger, but I know I can’t rely on it. Lets not forget these $150 triggers only work with one make and model flash that sells for $450, at that price point the $100 saved over the ST-E3-RT makes much less sense.

        On the other hand, I have nothing but praise for the RF-602’s I bought years ago and are still outperforming Pocket Wizards.

        • Author
          Flash Havoc 8 years ago

          Actually I think YongNuo are now extremely good at reverse engineering the protocol (not to say its not going to be an ongoing challenge).

          The thing is YongNuo are not trying to cater for professionals, they are making gear to a very low price for the widest market possible.

          With the technical skill they have now its really a shame they don’t offer a premium version built for professional use.

          • Privatebydesign 8 years ago

            “The thing is YongNuo are not trying to cater for professionals, they are making gear to a very low price for the widest market possible.”

            But that isn’t as valid when you are talking about only working with $450 flashes, saving $100 on a trigger isn’t paramount even to the non pros out there that are in the $450 per flash market.

            Absolutely the vast array of various third party offerings make much more sense to many, even pros, the third party flash choice is overwhelming 🙂 , and the radio choices now, both dumb and ETTL, are fantastic, built in radio in $75 flashes shows what can be done, and makes huge sense for most.

            “With the technical skill they have now its really a shame they don’t offer a premium version built for professional use. ”

            Couldn’t agree more, for the improved functionality over the ST-E3-RT I’d happily pay much more as my main bodies are pre 2012, if it worked 100%. I have said elsewhere I’d happily pay $1,000 for the functionality the YN-E3-RT gives my 1Ds MkIII’s, but it has to work every time.

            I am sure many will own the YN-E3-RT and never have an issue with it, I am sure there will be many happy owners, and like I said I don’t want to appear overly negative about it. But I just wish it had been ready for prime time, it is so, so, frustratingly, close.

    So my yn-e3 just came in.. Updated the firmware.. Having issues with it..

    – NO HSS
    – TTL there is a delay..
    – when I change settings on the yn in group mode, I have to fire press the pilot button on the yn before the changes take place on the flashes or else they stay the same as previous settings..

    Anyone else?

    • Privatebydesign 8 years ago

      -HSS is in M mode only.

      _No idea.

      -The changes are not reflected on the remote flashes until after they have fired, you don’t need to test fire them, just take a shot, the settings are not sent until you press the shutter button.

  18. Privatebydesign 8 years ago

    Sorry, Second Curtain Sync is M mode only, HSS works in Group and M modes but not ETTL mode or Multi mode.

    In Group mode it is menu 2, third button from the left; in M mode it is menu 2, second button from the left.

    Here is my situation. I have a Canon St-E3-Rt and now a Yongnuo YN-E3-Rt. I would like to use both at the same time and fire my 2 600’s. One on each hip (5Diii & 6D) They both work great by themselves and control both 600’s fine. When both are turned on one goes green and the other goes orange. When I turn off the green one the other turns from orange to green. Whichever is one 1st gets the green light.

    If you read the YN manual it says “Multi YN-E3-RT can share slave flashes”

    Am I reading this correctly? Can I have multiple commanders and control several slave flashes?

    I also cannot get the AF assist light to fire on my YN-E3-RT, anyone else have this issue?

    For those interested, I was able to get this to work on the Olympus EP-1. I had to tape over the TTL pins, but was able to fire in manual at a variety of power settings, provided I transferred the power settings to the 600-RT first by pushing test. HSS not working (firmware 1.09), or at least, _I_ couldn’t figure out how to get HSS to work.

    Hi Flash Havoc,

    Great article. I’ve got 3 600ex-rt’s that I shoot almost everything with. I am planning on making the jump to a Pentax 645z, and would love to not change my workflow that drastically. Do you have any idea if the YN-E3-RT would work? If I’ve read this correctly, I can still control the power output for all three flashes and trigger them all from the YN-E3-RT correct?



    • Author
      Flash Havoc 7 years ago

      Hi Sam,

      Yes that is correct. As long as the Pentax has a standard hotshoe then YN-E3-RT should work with remote manual power control of the 600EX-RT’s.

      Hi Brian,

      No they are not compatible unfortunately.

      For the YN560 IV flash you would need the YN560-TX transmitter unit.

      If you want more functions though like ETTL, HSS, Second Curtain Sync, you could keep the YN-E3-RT and exchange the flash instead for a YN600EX-RT which is compatible with the YN-E3-RT.

  25. Kryn 7 years ago

    The YN-E3-RT works flawlessly on a 5D2 (probably also on other Canon Cameras). It also works in manual control mode on a D800E. However, it does not seem to work on the D810, nor does it work on a Fuji S3, and it also doesn’t work an Olympus EPL5. It might be that camera settings are important, but if so, please let me know what settings to set the cameras mentioned to to make it work. I love the unit, but if I cannot use it on other cameras as advertised, then I’ll be looking at an alternative…

  26. Anthony M 6 years ago

    I’ve successfully used the yn-e3-rt with Canon 600ex-rt flashes using my 7D Mark II and Nikon Df. I mainly purchased it to use it with the Df and still have a Canon st-e3-rt as well. When I first received it, it was sluggish, and didn’t work consistently. After reloading the firmware, I’ve not had any issues using it with my Df. I’m loving the flexibility and now evaluating if I truly need to hold on to Nikon flashes just for TTL.

  27. Niels Gram 6 years ago

    From the release note for newest firmware:

    “2015.07.01 v1.18:

    Fixed: adjusted for new LCD/PCB design. (Please don’t update old firmwares
    with YN-E3 assembled after 2015/07/01, or the lcd won’t display correctly. If
    you have done that, please update with v1.18 again.)”

    So the hardware has had an update ! Wonder what was changed and why. Maybe only cost optimization. Mine must be assembled prior to 2015/07/01. It came with v1.16 firmware and it has worked well in my testing but I’ve had a glitch with the E3-RX where pressing “test” on the -RT would fire my 580EX-II but the flash didn’t fire with shutter release. I don’t know if this is a -RT or -RX glitch which is why I’m monitoring FW updates for both.

      Thanks for that Niels.

      I don’t quite follow what that update is though. Its adjusted for new LCD/PCB design, yet they are saying not to update the latest units. Then update with v1.18 again if you updated the wrong unit? I wonder if that was meant to read update back to v1.16 again?

    I just bought the YN-E3 and YN-600EX-RT, on top of the Canon 600EX-RT I previously owned as a Canon user. Now using Oly OM-D EM5-M2, it was unfortunate to see my set up could not work as intended. Funny enough, only Canon 600EX-RT fires from the YN-E3 seated on my Oly. Yongnuo’s version was not triggered.

    All firmwares are on latest version, no luck that it could not work. Any one has any workable solutions for YN-E3 seated on non-Canon cameras to fire off Yongnuos’s own 600EX-RT? Badly need this system to work and I think these combis will be perfect. It just seemed a firmware issue from YN-E3 side. But with the latest firmware only updated in July, it seemed highly unlikely any new updates are coming soon.

      Hi Jordan,

      Yes this is known issue unfortunately. And I’m not sure why YongNuo have not updated the transmitter or flash to correct the issue. Or aware of any work around unfortunately.

      You probably should contact service@hkyongnuo.com and let them know of your issue. The more people that mention this the more they may treat it as a priority.

  29. Niels Gram 6 years ago

    I verified the issue using a 1DIV earlier today. YN600EX-RT is at FW V1.8.1, YNE3-RT is at FW V1.16. There are a V1.17 and V1.18 for the -RT. Maybe the issue has been corrected without the fix being reflected in the release note so a FW upgrade may be worth trying. Ironically this proves that the YN600EX-RT and the Canon 600EX-RT actually doesn’t implement the radio protocol identically. Ups YongNuo .-(
    I don’t have access to a Windows computer so I can’t update the FW in my yn-devices 🙁

    Hey guys,

    I’m looking to buy a YN-E3-RT trigger in combination with the YN600EX-RT flash. I’d also like to expand my collection by buying other (cheaper) YN flashes like the YN650 III.

    Can I use the YN560 III in combination with the YN-E3-RT trigger and the YN600EX-RT?
    If no, what would you recommend to use both flashes (and in the future maybe more)?

      Hi saschavs,

      The 2 systems are not directly compatible at all unfortunately.

      As Niels mentions below, you could attach a YNE3-RX receiver to the YN560 III flash, or use the their built in optic slave. Though either of these methods would lose remote manual power control with the YN560 III flashes.

      What you could possibly do if you were really keen is to mount a YN560-TX transmitter on top of a YNE3-RX receiver, to fire and control the YN560 III flashes (with their own built in radio receiver). Though this would likely cause a small drop in maximum sync speed.

      UPDATE – I just tested the set up above, and I do just start to see shutter in the frame at 1/250th on a Canon 7D. Otherwise the remote control etc words fine. You have to mount the extra transmitter and receiver somewhere handy though.

      Ideally the best option is likely just to stick with all one system or the other though.

  31. Niels Gram 6 years ago

    You can use either the YNE3-RX to trigger the 560 from the YNE3-RT, or you can use the 560’s build-in optical trigger. I think the price of the 560 + -RX is abou the same as a YN600EX-RT so this really doesn’t make much sense. The 560III can’t be triggered directly from the YNE3-RT.

  32. Niels Gram 6 years ago

    I have both two 560 III flashes with 560 TX and the YNE3-RX/T and considered mounting the 560 TX on the E3-RX as you suggest. But I fear that the extra radio link will mean that I would get two light bursts (one from the flashes talking directly with the E3-RT and one from the 560’s) and since I want to catch fast moving action with the flashes two distinct light bursts would be very bad.

    Before I could test this setup in real life I found that the 560 radio system can’t follow the 10 fps frame rate of my camera so I didn’t bother to test the 560 TX mounted on the E3-RX. It is clear that the issue is the radio system since a 560 flash mounted on top of a E3-RX can follow 10 fps (at lower power levels and with external power). More over, the 560 radio system will miss frames at 10 fps even at 1/128 power (with external power).

    Of cause if you don’t use the flashes to catch fast moving objects like I do the above will not be an issue.

  33. Arkady 6 years ago

    I have a yn-e3-rt on a 1ds mkiii
    I’m using it with 2 x yn600ex-rt and 2 x yn565ex attached yne3-rx.

    Everything is on the latest firmware and it’s all working perfectly except for one little thing. I bought a third yne3-rx to use as a remote shutter release. I attached the link cable from the tyn-e3-rt to the shutter release on the camera.

    If I press the release button on the extra yne3-rx the flashes all fire. If I press and hold it for 1 sec the camera shutter is released, but the flashes don’t fire at the same time. Everything I’ve read indicates that remote release with flash should work and so I presume I’m doing something wrong, but I can’t work out what it is.

    All flashes are being fired in manual mode not eTTL.

    Any help would be much appreciated.

  34. PerChr 6 years ago

    I have a non-Canon camera (Fujifilm X-T1) and recently bought the YN-E3-RT and YN600EX-RT. The transmitter and flash connects and works when both are off camera. When I put the transmitter on the X-T1’s hot shoe, it doesn’t trigger the flash. It does trigger Canon flashes though (which I don’t have). I have the latest firmware on both transmitter and flash, have tried both normal and legacy mode, and have made the right adjustments in my camera (mechanical shutter only, exposure preview for manual off, forced flash).

    With firmware 1.07 and later it’s supposed to work, isn’t it?

    Have anyone with a non-Canon camera got the YN-E3-RT and the YN600EX-RT working?

    • Demos 5 years ago

      I have the same issue did you manage a fix on this?

  35. Niels Gram 6 years ago

    Oddly the YN600EX-RT does not support the YN-E3-RT when it’s in legacy mode… you can read that elsewhere here on flashhavoc.com. YN-E3-RT legacy mode only work with the Canon 600EX-RT. You may get it to work if you place your YN600EX-RT on an YN-E3-RX, but I haven’t tried legacy mode on the YN-E3-RT in this setup.

  36. PerChr 6 years ago

    Thanks for replying, Niels.
    The YN600EX-RT has RT (or RF in Canon’s terms) receiver built in. Are there any transmitters that will trigger it from a non-Canon camera, without additional receivers attached to it? I’m trying to have as few components as possible. If no, I will invest in another system (transmitter –> flash without separate receiver). If thats the case, what would you recommend (YN560-TX/560-III/IV, Cactus V6/RF60…)?

  37. Hammad 6 years ago


    I’ve been reading articles on this Web since quite a time! I can’t pose my question prior to saying that you guys are amazing. What wonderful team you got there!! Such apt articles and reviews and news updates. I must say, I’m impressed.

    This is my first comment/query on this web, and here’s my question:

    I’ve read the above article which states, with a firmware update installed, you can get YN-E3-RT to work with any non canon cameras. Okay, lets get specific.

    Can I use it mounted on Nikon bodies (D7100 and D750) to fire “YN-600EX-RT” flashes? No TTL needed, since I’m okay with manual operation to adjust powers from the controller. Plus, can I shoot HSS?

    I don’t personally like the idea of attaching Receivers in the feet of the Flashes, Since it gets very bottom heavy when I have to mount it on Godox S-type flash bracket with my Soft boxes! That’s probably why I didn’t invest in Yn-568EX, Yn-622N and TX combos! I want fewer components. Yet, I want to upgrade from Yn-560III system, in order to be able to go beyond this annoyingly typical 1/250th Flash Sync Speed, but with cheapest possible alternative!

    Help, please?

    P.S, I heard, Yongnuo coming up with an upgraded version of Yn-568 with built in radio receiver for Nikon? When can we expect it to release?

    Thankyou soo much! 🙂

      Hi Hammad,

      As Niels mentioned below this will not work with the YN600EX-RT at the moment, only the Canon 600EX-RT.

      Though you wouldn’t have access to HSS using Nikon bodies then in any case.

      Have a look at the TT600 flash I just posted about from Godox. Combined with the TT685N master flash this sound like exactly what you’re looking for (don’t worry you’re definitely not the only one).

      I’m not 100% sure if the HSS mode is turned on and off automatically when using a master flash like the TT685N. If not though the worst case is you may want to use all TT685N off camera as well ($110 vs $75 for the TT600).

  38. Niels Gram 6 years ago

    You asked: Can I use it mounted on Nikon bodies (D7100 and D750) to fire “YN-600EX-RT” flashes ? No, unfortunately, this doesn’t work with the YN-600EX-RT. It should work with the YN-E3-RT and Canon 600EX-RT flashes. Maybe the YN-600EX-RT will get a firmware upgrade that makes it work but there has been no signs of it thus far. Hope this helps.

    • Hammad 6 years ago

      Hi Gram,
      Thank you very much for your reply. Sadly, It seems like Third-Party lightning accessories manufacturers do not or probably least care about Nikon Shooters. Well, no wonders, cuz Nikon itself doesn’t care about them either, There’s been no Flash with built-in radio till date. They have announced one (Sb-5000), this month, but its still not available in the market.

      I’m really looking forward to Yongnuo giving us a decent unit allowing to shoot HSS without having to attach lousy receivers in the feet. Much anticipated Yn-586-ii is taking realllly long to come!

      Disappointed Nikon user!

    Hi Flash Havoc,

    I’d like to start by saying thank you for a great place to source information.

    I have looked through and not sure if i have missed the answer to probably a common question.

    In a nutshell is there anyway to trigger YONGNUO YN-600EX-RT ‘s using the Yn-e3-rt on a fuji xt1?

    Kind regards

    • Author
      Flash Havoc 5 years ago

      Hi Demos,

      Thanks for that. Yes you can use that combination on the Fuji, though you would only have remote manual power control, no TTL or HSS etc.

      So if this is just for use on the Fuji you would likely be better off with simple remote manual YN560 III flashes and YN560-TX transmitter. (Or possibly better still the Godox equivalent TT600 flashes and XT32 transmitter).

      With the YN-600EX-RT and YN-E3-RT though, you need to set the transmitter to single firing pin mode, so that it doesn’t have issues communicating with the camera.

      • Demos 5 years ago

        Thanks for your reply Flash Havoc,

        Your pretty certain using a Yongnuo YN-E3-RT i can fire Yongnuo’s YN-600EX-RT flashes with the Yongnuo YN-E3-RT on a Fuji Xt-1?

        Everything i have tried doesn’t seem to work?

        Many thanks

          Hi Demos,

          My apologies, this will not work with the YN600EX-RT on any camera other than Canon DSLR’s.

          It does work using the original Canon 600EX-RT and the YongNuo YN-E3-RT as transmitter.

          Unfortunately this was just a quirk with the YN600EX-RT which YongNuo do not appear to have been able to resolve.

  40. Eric 5 years ago

    So far I’ve tried the combination of YN-E3-RT + YNE3-RX and it works well with my Canon cameras. However, when I pop the YN-E3-RT on my A7R2 hotshoe, it is still able to transmit information to the YNE3-RX receiver, but the flash doesn’t go off when the shutter is pressed 🙁

    • Author
      Flash Havoc 5 years ago

      Hi Eric,

      I just tried this with my A7 and got the same result unfortunately. It appears the YNE3-RX will only fire when using the transmitter on a Canon DSLR.

      I’ll have to search around to see if there is possibly any way around this, though its sounds like it is likely just a limitation of the YNE3-RX unfortunately. The YN600EX-RT has the same issue.

      • Eric 5 years ago

        Thanks for your reply. Hopefully there is a work around or it will be addressed in future firmware updates. Fingers crossed!

  41. Kai Andrew Mallari 5 years ago

    I’m planning on ordering a few YN600EX-RT’s to be triggered by the YN-E3-RT.

    Does anyone know if this would work with the Sony Alpha SLT-A77ii?

    Only looking for the ability to change settings remotely and remote trigger the flash.

    • Author
      Flash Havoc 5 years ago

      Hi Kai,

      Neils is correct there, it only works with the genuine Canon flashes like the 600EX-RT, (ironically) not the YN600EX-RT.

      Are you wanting to use them with Canon cameras as well (for TTL etc), or just for Sony?

  42. Niels Gram 5 years ago

    @Kai: It does not work. The transmitter work with Canon flashes but that’s very expensive. Look elsewhere for a less expensive solution.

  43. steve 4 years ago

    Have just received the Yongnuo YN-E3-RT transmitter and 2 Yn600ex-rt ll.
    I cant get the YN-E3-RT to trigger the Yn600ex-rt ll when the trigger is fitted to my Olympus EM5 II.
    It will fire the flash if I press the test mode button but when I take a picture the flash is not firing.
    The YN-E3-RT has the latest firmwear update and according to the Yongnuo site the Olympus should fire the flash.
    Has anyone got the same set up and managed to get it to work.
    this is from the site
    Fixed: improved flash syncing with cameras after 2012.
    Added: Legacy flash trigger (for non canon cameras). Now you can use YN-E3-RT
    on non canon cameras with standard iso hot shoe. You need to press test the
    test button to transfer the M mode parameters.

      Hi Steve,

      Possibly a silly question, though do you have the YN-E3-RT actually set to Legacy mode?

      • steve 4 years ago

        i did try it on legacy mode but still couldnt get it to fie the flash. if i put the flash directly onto the camera it works, but when the transmitter is one the camera its not firing the flash. just wondered if there is something im missing to get it to work

        • Author
          Flash Havoc 4 years ago

          Ok, sorry, if you look at some of the comments just above, unfortunately this only works if using a genuine Canon RT flash with the YN-E3-RT transmitter.

          It seems pretty silly, but the YN-600EX-RT won’t work, and it sounds like that has not been improved in the YN-600EX-RT II unfortunately.

  44. Alina 3 years ago

    This firmware update is not going to make the YN-E3-RT work on a nikon, at least not on the D800. The dumbest thing about this is that the YN600EX RT flash DOES work on my nikon and they both have the same hot shoe but despite that, that damn transmitter is still non functional with nikon. *eyeroll*

  45. Daniel 3 years ago

    I see there’s YN-E3-RT II out now that allows the user to update firmware when new releases come about. Does this new model still maintain the compatibility to be triggered by a non-Canon camera for manual control of 600EX-RTs?
