    I would like to know if you put a yn-e3-rt on top of a Yn622c work, why I want to do this? so I can trigger my two 600ex-rt with the Yn-e3-rt and trigger my two strobes with the Yn622c at the same time, any idea? I have already the Yn-er-rt which work very good with my 6D.
    I can trigger the strobes already if I set them as slave but if I need to go over 1/125, I already have the

      Hi Mel,

      You definitely can’t run both units as TTL transmitters at the same time, as they are both trying to communicate with the camera at the same time.

      But the YN-E3-RT has a remote manual compatibility mode, so if you only want basic firing, and remote manual power control with the 600EX-RT, then you could likely stack the YN-E3-RT on top of the YN-622C in this mode. (Or worst case scenario would be to cover the TTL contact pins between them).

      But at the end of the day, the best option would be to just use extra YN-622C receivers on the 600EX-RT as well. And when the YN-622C-TX is available, use that as the transmitter for all the flashes.

      It’s a shame to have to use YN-622C on the 600EX-RT when they have their own radio, but its going to be a lot more practical and functional. Otherwise it would best to move on to all RT gear. Maybe trade your old non RT flashes for YN-600EX-RT when they are available.

      The YN-622C-TX should be a good alternative though, and relatively inexpensive for one of those and a pair of YN-622C.

        Flash havoc, maybe you can help me figure this out.

        I have the YN E3 RT, I use it to control 2 Canon 600 EX RTs and 2 Yongnuo 600 EX RTs. Through my 5D III, everything is just how it should be, all functions are perfect and all flashes fire as expected. When I attach the YN E3 RT to my Fujifilm X-E2, with the E3 RT in Legacy mode, all set to manual, it will only fire the Canon flashes. I can test fire and all flashes fire, but when it comes to pressing the shutter, only the Canon flashes will fire.

        I am struggling to find any information anywhere on this. This was the only reason for purchasing the YN version alongside my Canon version, as the Canon doesn’t work with the Fuji’s.

        Hopefully it is something you can help with, or anyone else in here that has this combination and has figured it out.

        Thanks

      Thanks for that.

      I’m not sure why it has remained as a beta update for quite a while though.

  3. Cameron 1 year ago

    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 on 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?

  4. privatebydesign 1 year ago

    Cameron,

    Yes that is correct, it is all working as it should, you can have multiple “Masters” the first is the “Main Master” the rest, and there can be more than two, is a “Sub-Master”.

    Any of the masters has complete control of any and all flashes and the settings can be completely different, even the modes and groups.

    I use the yongnuo yn-560 ii and I am looking for a way to remotely change the power settings. Does the YN-E3-RT do this and is it compatible with the yn-560’s?

    Thanks,

      Flash Havoc 1 year ago

      Hi Nick,

      Unfortunately no, there is no way to remotely change the power setting with the YN-560 II, as that function was never built into the flash.

      The YN-560 III does have a remote manual power control built in, but we are still waiting on the dedicated transmitter unit which will enable that.

      The only remote manual option currently available with a transmitter are the Godox V850 (and they are great flashes).

      • Nick 1 year ago

        Thank you for the response… I have been researching a little and was wondering if I can accomplish changing power setting remotely using the YongNuo YN-E3-RT and Yongnuo YN-565 EX.

        If you have a better solution that would great.. When I need to change power setting on any of my flashes I have to open up the soft box and change it manually… I am trying to eliminate this… Would like to accomplish this is the cheapest way

        Thanks,

          Hi Nick,

          Sorry no the YN-E3-RT are only compatible with the Canon RT gear, and the coming YN-600EX-RT flash.

          The cheapest way will be the YN-560 III flash and the new dedicated transmitter (though we don’t know when that will actually arrive).

          But for a little more than that you can get the Godox V850 flashes and FT-16 transmitter, which are available now (and arguably a much better option anyway).

          • Nick 1 year ago

            I took your advise and got the Godox V850 you suggested and I love the flashes and the transmitter receiver combo… Great product so thank you …. One question I do have is do I need to get a different transmitter to take advantage of High Speed Sync?

            Thanks for all the help,

              Hi Nick,

              Ok great, thanks. Yes for HSS with Canon the simplest way would be a Godox Cells II transmitter.

              You can see some other options here as well. Though the Cells II are a good option if you don’t need to trigger other TTL flashes etc. Thanks.

    Looks like YN-E3-RT firmware v1.10 was released.

    Change log:
    Version 1.10:

    Fixed: couldn’t set fec of group b/d via camera menu.

    Version 1.09:

    Fixed: update limit of flash number in Multi mode.
    Fixed: disable HSS in multi mode
    Added: P.FN: legacy trigger mode. When it’s set, YN-E3-RT won’t detect ettl
    input so that it can be used on Fuji hotshoes.
    Added: P.FN: Free Mask Group. This setting is used with GR/*. Free mask will
    be on/off when you hold GR/* button for a few seconds. When Free mask is on,
    groups not in this setting won’t fire. So you can take a photo with background
    flashes only quickly.

    • Giles Evans 5 months ago

      I just received my YN-E3-RT with firmware v1.14 can anyone explain the usage of the Free Mask Group setting in P.Fn22 when the group button is long pressed does it only fire the flashes selected in P.Fn22 or does it fire all but those flashes?

      Also has anyone tested or reviewed the new YN-E3-RX receivers? Will they allow the use of my “legacy” ETTL flashes such as the YN-568ex, Canon 580ex II, Nissan DI866 or even Canon 430ex in the RT System? Can they be used (non-TTL) to trigger studio lights? Will they adapt well to the new TTL studio lights from Yongnuo, the YN300W? I’m curious as to if these new receivers could replace my existing YN622Cs.

        Flash Havoc 5 months ago

        Hi Giles,

        I have not used the Free Mask feature, though Alexander from YN622C.RU will likely know more about this as he requested the feature.

        Regarding the YNE3-RX, yes this works well with the YN-568EX and Canon 580EX II. I’m not sure about the Di866 II, and not sure about MK I flashes like the 430EX either.

        Regarding the YN300W, here is a copy of another recent reply on this –

        I haven’t checked if there are any firmware updates for the YN300W, but I just tried with the YNE3-RX and there appear to be some bugs.

        They do actually appear to work together in ETTL or manual. Though the YNE3-RX cause a few quirks. Firstly the recycle beep locks on constantly after I take a shot, so I had to disable that. The flashes interface is also mostly disabled, so I can’t turn the modeling light on or off without switching off the receiver first.

        Otherwise the ETTL and manual do appear to work ok. A firmware update should hopefully be able to fix the other quirks.

        The YN300W are pretty cool lights, though if you’re not aware they do have massive color shift from around 1/4 power down.

        1/1 to 1/4 power is 5400K to 5600K +2, which is ok.

        Though from 1/8 to 1/128 is 5900K +7 to 8300K +37

        So the shift across the entire power range is nearly 3000K!

    Quick question if anyone can please help. I want to buy one of these but need to know if it does HSS with the canon 6d! I know the canon version only allows HSS with the 5dmk3 and the 1d, no HSS is a deal breaker for me using the 6d and being stuck at 1/180th. Thanks again

      Hi Joe,

      Yes the YN-E3-RT will work with HSS with the 6D.

      Are you sure the Canon ST-E3-RT will not work with the 6D in HSS? I have not heard about that issue? Thanks.

  8. zak 1 year ago

    will this enable high speed sync between my 600ex-rt and my 7d? is there anything that works differently (or not at all) than when my flash is on camera? this looks like it might be a better option for me than the ST-E3-RT.

    thanks

      Flash Havoc 1 year ago

      Hi Zak,

      Yes it should work with the 7D with HSS.

      I think most functions should be the same as on camera, though Second Curtain Sync is only available in manual with the YN-E3-RT. Thanks.

  9. zaakir 1 year ago

    Having consistency issues with the 7D in ettl. first couple shots are fine, then either a full flash dump, or a misfire all together. In manual mode there is no issue, so there’s obviously a communication problem with the ettl metering.

    Seems to work fine with my 5D3, anyone else having issues with the 7D?

    I’m still on 1.08 as far as firmware.

    • Author
      Flash Havoc 1 year ago

      Hi zaakir,

      I’m not sure about any specific issues with the 7D. It may just be more of an issue with your 7D hotshoe being a little different.

      If you haven’t already done it, try cleaning the hotshoe contacts with some Isopropyl alcohol or similar.

      There is so much movement in the YN-E3-RT foot in the cameras hotshoe, and then the pins move around in the YN-E3-RT foot as well. So it doesn’t surprise me some people are going to experience issues.

      I really hope YN do something better with the coming YN-600EX-RT Flash foot.

  10. zaakir 1 year ago

    OK so after cleaning the contacts and extensive testing, I’ve determind there’s an issue with the/my 7D.

    The trigger works flawlessly with my 5D3, and even my mirrorless EOS-M. On the 7D however, it misfires. It even does it when you hit the FEL button. I didnt get full power dumps this time, but a number of misfires.

    I then decided to use a 600ex on the 7D as a trigger for my other 600ex, and viola, no issues what so ever. So apparently there’s a communication issue somewhere. Perhaps upgrading the trigger to 1.10 would help.

    further testing needed…

      Go into your Device Manager and right-click scan for changes with the device attached. The latest version of the updater does not quite install correctly. I cannot recall the exact steps I did, but I was able to get the device detected after doing something in that area. There may have been a “splat” and I had to search for drivers for it.

  13. Marsu42 1 year ago

    Do NOT get this unit, it is unreliable and a waste of $150. I am stunned Yn dares to sell it like this.

    The af assist is a joke (misaligned on my unit, but even if not you have to wiggle the flash in the hotshoe to make a dot match a af sensor), the range is pitiful (~10m if you’re lucky and ~2m if near ground level) and worst of all it is useless for mission critical work: The Yn unit often loses connection with flashes and you have to power-cycle the controller, but worst of all the Yn shows “connected” but some flashes simply refuse to fire! A 1:1 comparison with a 600ex-rt shows that clearly the Yn controller is to blame.

    You’re better off with using a good ol’ optical link if line of sight allows it, this is a catastrophe and only “worth” it if you’re desperate to use rt with pre-2012 camera bodies. Remote 2nd curtain doesn’t work in group mode if you were wondering btw, just in a:b:c ratio mode.

    I hope Yn at least adds some reliability with fw updates, but now I understand why we haven’t heard anything of their other announced rt flashes. Time to apologize, Yongnuo!

    • Marsu42 1 year ago

      Addition: I am using fw 1.10 on 6d and 60d, issues are the same on both. On another note, once you set the 6d to 1/2 stops exposure level increments the in-camera flash menu is gone as Yn only supports 1/3 stops.

    • Author
      Flash Havoc 1 year ago

      Hi Marsu42,

      A few people have reported range issues with the YN-E3-RT, but they are a small minority so far.

      I think the AF light needs to be fixed, or at least returned to the smaller pattern the YN-568EX etc has, but then not everyone agrees on that either.

      I have a few issues with the build quality of the unit I have, but again the vast majority of people have been quite happy with their units.

      With the low price comes some variation in quality control etc, you can say the same thing about the YN-622. They are not for everyone, but if you were to take them all away there would be a lot of very upset people.

      So your experience and expectations are not the same as everyone’s.

      Before YongNuo released the YN-E3-RT I was getting the impression this would be a higher end product at a higher price. But it didn’t really turn out that way, and that’s not really what the majority of people want anyway. But it would be great if YongNuo would provide a premium version as well, as their engineering skills and the feature set are very desirable to many people willing to pay more for a higher build quality version as well. Thanks.

      • RDW 1 year ago

        I agree with you Flash Havoc, I think the whole purpose of Yongnuo (other than copying Canon and Nikon products) is to provide many people with knockoff products who can’t or won’t pay the higher prices for the “name brand.”. I have had no issues with my Yongnuo products and of course I expect them to be lesser build quality, otherwise, you might as well pay the full price for the “name brand.”

        I always say, “you can get a bad batch of something every now and then, no matter what is is, or who it’s made by or how much it cost”. I know for sure that Canon, Nikon, Sony, Mercedes and all the other manufactures have great products where they have a bad build every now and then, so I expect no different from this company. Now that said, if you are the one who happens to receive that product from the bad batch, it will definitely make you write a bad review and have a negative opinion of the company and/or their product. But most reputable companies will replace a bad product (withing the warranty period) with a new one.

      • David Paden 1 year ago

        My only problem with the ST-E3-RT is it quits working after 10 or 15 minutes. I can turn it off and on and it will work for another 10 or 15 minutes. Very disappointing! Everything else works great. I have not tried a range beyond 6 or 8 feet.

  14. Nez 1 year ago

    Hello, just wondering if the YN-E3-RT works with flashes driven by the YN-622C’s (ie – 430EX which doesn’t have wireless transmission without a separate trigger attached). Many thanks!

      Flash Havoc 1 year ago

      Hi Nez,

      No, the YN-E3-RT only works with RT units. So at this stage only the Canon 600EX-RT flash (and the YN-600EX-RT when that is available). Thanks.

  15. jerome 1 year ago

    Ha, i bought it following this review, but seemed to have missed this line
    “The YN-E3-RT (and coming YN-600EX-RT flash) are not directly compatible with the YN-622C TTL triggers, or manual RF-602/603/YN-560 III systems.”

    I own 2 YN 560 III and a canon 430 ex coupled with 2 YN 622. A bit bummed yesterday when the transmitter arrived and i spent 2 hours trying to figure out why it didn’t work!

    I guess i should sell it back then.

    Is there a transmitter you could recommend for my 3 flashes by any chance?

    Many thanks, Jerome

    • Author
      Flash Havoc 1 year ago

      Hi Jerome,

      Unfortunately the 3 systems are not directly compatible. We have discussed that previously here.

      The YN-622C (and coming YN-622C-TX) can fire the YN-560 III, but no remote power control like the coming YN-560-TX should eventually provide for the YN-560 III.

      So its really a matter of choosing one system or the other. The YN-565EX II flashes would be more compatible with the YN-622-TX / YN-622C. Thanks.

          Thanks, no worries.

          I should also mention though, the YN-560-TX will likely stack on top of a YN-622C as transmitter. So it may be possible to fire and control those 2 systems with a little bit of a workaround there.

          Though you wouldn’t be able to stack the YN-560-TX on top of the coming YN-622C-TX, as that does not have a pass through hotshoe on top.

    I’m having the same issues as Marsu42 with the YN-E3-RT trasmitter not working farther then 2m. It’s constantly loosing a slave or all flashes and has to be reset. I you are a professional and having paying clients do not waste your time with the yongnuo trasmitter.

    Two month update:

    Everything is still working great with my 5D mark III. Just shot another wedding and zero issues.

    Those of you experiencing distance issues, are you doing a scan to find the strongest channel? I notice if i have this issue, then do a scan, the channel im on usually doesnt have the highest signal strength. DO A CHANNEL SCAN!!!

    All this being said, the issues with the 7D remain. Im still quite happy with the unit and it continues to work well, even the AF assist has saved me in some dark situations. as long as the center AF point can pick up the beam i have no complaints.

    Couldn’t wait any longer for the Yongnuo 600ex-rt knock-off and dropped the Visa card on three Canon 600 EX-RT Speed lights. No regrets, they’re fantastic.

    Something I’ve read from a few Yongnuo YN-E3-RT users is the surprisingly limited range…sometimes under 5 meters. Are these one-off instances, bad copy or user error situations or is the YN-E3-RT severely distance limited? I can understand a reduced range outdoors, but is the 5m range about it? And if so, is the genuine Canon unit any better in this regard. Personally I’d be happy with either but the focus-assist is the clincher for me. With my old 580’s I used YN 622C’s purely for focus assist for dark/night event work.

    Hi there. I have the same issue as marsu42 and others with the poor range of the yn e3. With the canon 600 rt as trigger the range is way biger.

      Flash Havoc 12 months ago

      Hi Paul and pwp,

      It does sound like there are some somehow faulty units providing less range than others. If changing channels or using the channel reception test doesn’t help you may have to return them and try another transmitter.

      @ pwp – The Canon system generally gets around 30 meters safely as the the YN-622 etc. The can go much further with clear line of sight and no interference, but 25 – 30 meters is more around the safe general working limit.

    Is anyone else unable to get the firmware update? I’ve had my YN-E3-RT for a few months and it has NEVER worked. The links on the site posted above on July 20th don’t work. Right now this thing is worthless. Any suggestions? I’m going to contact Amazon and see if I can return it.

    Might be a stupid question but I cant seem to find a clear answer anywhere. I have a YN-560 II and the E3 transmitter. Is there a way to remotely fire my flash with the transmitter or do I have to upgrade to a better flash to be compatible with the E3 (if so what are my options) ? Thanks!!!!

  24. tallbamboooo 6 months ago

    I just bought a Yongnuo YN-E3-RT (firmware 1.14) and a YN600EX-RT (firmware 1.8.1), which work flawlessly on my Canon 5DIII. But I would like to use the system manually on my Fujifilm X-T1. When I put the YN-E3-RT on my X-T1 and turn on the Legacy Mode, I could transmit the M mode settings to the speedlite via the test flash button. However when I pressed the shutter butter, the speedlite would not fire.

    I have also tried to put the transmitter on another non-Canon camera, but still no luck. Then I put the transmitter back on my Canon 5DIII (still in Legacy Mode), the problem still persists. Switched off the Legacy Mode, then the transmitter worked flawlessly with the 5DIII.

    Do you think that I have a defective transmitter or was the latest firmware the culprit?

    • Kryn 6 months ago

      I did some testing on this. There may be a bug with the latest firmware (1.14), because the “Legacy” option doesn’t do anything for me either. Actually, my YN-E3-RT works on Fuji, Olympus, Nikon, Leica, and Epson, but the legacy option doesn’t seem to do what it’s supposed to. On my Nikon the Legacy option actually prevents the Canon speedlites to be fired, whereas with the option switched off, it works just fine in manual control. Try with the option switched off. It worked for my X-Pro1.

  25. Kryn 6 months 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. Kryn 6 months ago

    After some investigation I found the following that could be useful to others:

    First I should state I have both the original Canon 600EX-RT and the Yongnuo variant. I used both in my testing. The firmware of the YN-E3-RT is 1.14, the firmware of the YN600EX-RT is 1.8.1.

    The YN-E3-RT has a custom Function called “Legacy”, which can be accessed by long-pressing the CFn button. The intend of this function is to allow the YN-E3-RT to be used for Non-Canon Cameras. I used this function to assess the different operation modes.

    Note that in the test cases below, only Manual mode was tested, as this is primarily a test to assess compatibility with other, non-Canon, cameras.

    Camera “Legacy” Canon 600EX-RT YN600EX-RT
    D810 Off Yes No
    D810 On Yes No
    M8.2 Off Yes No
    M8.2 On Yes No
    R-D1u Off Yes No
    R-D1 On Yes No
    X-Pro1 Off Yes No
    X-Pro1 On Yes No
    E-PL5 Off Yes No
    E-PL5 On Yes No
    5D2 Off Yes Yes
    5D2 On Yes No

    During this test I also noticed that the YN600EX-RTs had a rather long power recycle time. The YN-E3-RT has an option for setting the speedlite power output when pressing the “Test” button. The function seems to work as required when working in ETTL mode for both the Canon 600EX-RT as well as the YN600EX-RT. However, the function does not seem to work for the Canon 600EX-RT nor for the YN600EX-RT when working in Manual mode. It appears that when in manual mode, this function is disabled, and the test button assumes the power setting set on the controller for the relevant speedlite. Since the transmitter requires the user to push the “Test” button each time settings are changed (applies to both the Canon and the Yongnuo speedlites), this could cause the batteries to drain unnecessarily. Also note that since it only works in ETTL, this means you can will only have this option available with Canon cameras when shooting in ETTL.

    My conclusion is:
    1) The “Legacy” Switch is not working at all. It does not have an effect when using the YN-EX-RT in conjunction with a Canon 600EX-RT.

    2) When used with a non-Canon camera, the YN-E3-RT only triggers Canon 600EX-RT speedlites. It does NOT trigger the YN600EX-RT speedlites.

    3) The Test power option only works in ETTL, which means using a Canon Camera. In Manual mode the “Test” button will result in an output from the speedlites equivalent to the setting on the YN-E3-RT.

      Hi Kryn,

      Thanks for the details on this. This sounds like it must be a change in firmware V1.14 for the YN-E3-RT.

      You might want to let YongNuo know about your results at service@hkyongnuo.com

      I still have V1.13 installed, so I will have a closer look at how that is acting.

      I have uploaded V1.13 here if you may need that for the moment instead.

  27. Tallbamboooo 6 months ago

    Thanks very much, Kryn, for the comprehensive testing. It looks like that there is something wrong with firmware 1.14. Maybe it is for this reason they have not posted it on their website, which still has 1.13.

    Flash Havoc, are you saying that the legacy mode does work in firmware 1.13? If so, can we downgrade the firmware back to 1.13 without problem?

    • Author
      Flash Havoc 6 months ago

      Hi Tallbamboooo,

      I haven’t had a chance to test it now to be sure, but there had been no complaints previously, and I don’t recall noticing any issue.

      I don’t have a Fuji camera though to test either, which is the main one the mode was originally implemented for. Most other cameras likely do work fine with the legacy mode off anyway.

      Where are you guys getting the V1.14 firmware from then?

      Yes you should be able to revert back to 1.13, unless there is something special in 1.14 that would cause an issue now, though that is pretty unlikely.

  28. tallbamboooo 6 months ago

    Thanks, Flash Havoc. I bought my Yongnuo gear in Hong Kong last week.

    • Author
      Flash Havoc 6 months ago

      Ok thanks, I see now, you have bought the YN-E3-RT with V1.14 installed already.

      In that case it could well also be the new hardware version YongNuo have mentioned. So I’m not sure now if there could possibly be some issues that may arise from reverting back to firmware V1.13 then.

      If you’re not in any hurry to use the legacy mode it may be better to wait until YongNuo provide another firmware update to rectify the issue then.

    • Author
      Flash Havoc 6 months ago

      Ok I can confirm similar results to what Kryn reported when using V1.13 as well unfortunately.

      With the Canon 6D & 7D the YN600EX-RT will not fire with Legacy mode On. While the Canon 600EX-RT does work with Legacy mode On or Off.

      With the Nikon D7000 the YN600EX-RT will not fire with Legacy mode On or Off. While the Canon 600EX-RT does work with Legacy mode On or Off.

      With the Sony A7 the YN600EX-RT will not fire with Legacy mode On or Off. While the Canon 600EX-RT does work with Legacy mode On or Off.

      So somewhere back in the firmware this must have changed, as the Legacy mode was there to provide a solution for Fuji as they were having issues.

      • mikeyang 6 months ago

        Do you know if it will work with Canon 1Ds III?
        thanks.

  29. tallbamboooo 6 months ago

    Oh, thanks again. I am not in a hurry to use the legacy mode and so I shall wait for the next update. I am a bit disappointed as one of the main reasons for me to buy the YN-E3-RT is to use it on non-Canon cameras. The important point now is to let Yongnuo know the problem. I have already raised this problem in Yongnuo’s facebook page and have also sent an email to them. If convenient, I suggest that Kryn and Flash Havoc should also let Yongnuo know your testing results. Thank you all very much again.

  30. Brett 6 months ago

    Perhaps this is a stupid question, but is there any advantage to using a YN-E3-RT to control off-camera YN-600EX-RT flash units, instead of using another YN-600EX-RT? It seems like for the small difference in price, it would make more sense just to buy another flash rather than the transmitter.

  31. Andy 6 months ago

    I just got YN-E3-RT. The firmware version is 1.12
    It works fine with Canon 600EX-RT. There are two things i don’t really like :

    1. When i change power level on YN-E3-RT, i don’t see the level changed in Canon 600EX-RT, even though the actual power changed (i verified the exposure with pictures on different settings). So, i’m not sure if this is the way YN-E3-RT designed? or i missed something?

    2. The lock on hot hot is not tight. With Canon 600EX-RT, i can hear it click and resistance when i lock the flash, but not with YN-E3-RT ( i can lightly twist it).

    I probably return it and buy Canon ST-E3-RT.

    Thanks.

    • Author
      Flash Havoc 6 months ago

      Hi Andy,

      1. No there is something wrong there. The power level change may not display on the flash straight away, though as soon as you press the test fire button or fire the camera the new power level should update on the flashes display.

      I can’t think off the top of my head how you could be having the power level change, but not display on the flash.

      2. I have one of the first version YN-E3-RT units, and yes its very loose (twisting side to side) in the camera hotshoe. I haven’t update to a later transmitter yet to test this myself, though other people appear to be indicating theirs were not so loose.

      Its only recently (since the second version YN600EX-RT flash) that YongNuo have had the neater fitting feat. Though again I have 2 early versions which are very loose, and I haven’t confirmed myself what the new foot is actually like. Or received foot width measurements from anyone to compare.

      The dial on my YN-E3-RT and YN600EX-RT flashes are completely fine so far. I think you are the first complaint on that here, though Alexander from YN622.RU has said some YongNuo owners have complained of issues with the dial.

      All in all I’ve never really had any functional issues with the YN-E3-RT, except for the fact that the range is quite limited (if you need longer range). There was meant to be an updated version YN-E3-RT along with the YN-622C and YN-622C-TX, so I’m giving it a bit of time to hopefully pick up a new model.

      If you don’t need the extra features (particularly GR group mode for pre-2012 cameras, or AF assist, or remote manual use on other cameras) then yes the Canon ST-E3-RT is a better option, particularly for the range. For $100 I find the YN-E3-RT is great on my 7D though, and now Sony A7 as well for remote manual use. And sometimes the AF light is really needed as well.

      • Andy 6 months ago

        Hi Flash havoc,
        1. Which mode do you set on 600EX-RT (or YN600EX-RT). i leave it ETTL on 600EX-RT. I think it acts the same way when i use PW TT1/TT5 with 580EX II. With PW, i also use AC3 to change power setting and i never see power level changed on the flash.
        So, when you change power level on your YN-E3-RT, you see power level changed in YN600EX-RT? May be Canon is different but i expect YN600EX-RT is the same. My YN600EX-RT will be delivered in a few days. I’ll test it before returning YN-E3-RT.

        One thing is i can’t download any driver/firmware from Yongnuo site. It keeps saying connection timed out. No problem in my site as i can download perfectly fine from other websites.

        2. Even though YN-E3-RT does not sit tight on the camera hot shoe, it does not go anywhere unless i twist it. So i can live with it. But if my unit is not working well, then i will need another exchange or something.

        3. About group feature, i don’t need more than 3 groups. My camera is 1Ds III and it is pre-2012 camera. If ST-E3-RT works fine with only 3 groups, i’m ok, except that no group at all.

        Thanks

        • Author
          Flash Havoc 6 months ago

          Ok the flash needs to be set to radio slave mode. Once there it shows ETTL on the display to start with, and you have no option then of changing that mode to manual on the flash itself.

          But when you set the corresponding group to manual on the YN-E3-RT transmitter, and then press the test fire button (or take a shot while the transmitter is mounted on the camera) then the flash should change to show manual mode on the display as well.

          Try doing this with the transmitter off of the camera hotshoe as well, just in case this is possibly an issue with the 1Ds III camera.

          Maybe you should try updating to V1.13 on the YN-E3-RT if you still have the issue. I’m not sure if I ever used V1.12 to see an issue like this.

          I should have V1.13 here if you haven’t found that firmware.

          Yes 3 groups are ok, its just that you can’t mix ETTL and manual groups without group mode. I don’t like the A:B C ratio in ETTL that much either. But 3 groups in manual are fine without group mode.

          • Andy 6 months ago

            Hi Flash Havoc,
            I’ll try again, but i doubt it works as you described. I didn’t expect RT system is complicated like that.
            I downloaded FW V1.13 here, but i still need the driver download which i couldn’t connect to Yongnuo site (timed out connection). Very frustrated with their website though
            http://yongnuo.com.cn/usermanual/pdf/YN_Trigger_Updater.zip

            Thanks.

            • Andy 6 months ago

              UPDATED:

              I’ve just tested them again. On M mode, i can see power level changed on Canon 600EX-RT when i change it on YN-E3-RT, except E-TTL mode.

              1Ds III has max speed sync to 250. But i’ll see tiny black line when i shoot at 1/250. With 1/200, everything is fine. Based on Canon manual, 600EX-RT will have less 1 stop if used with pre-2012 camera. I thought it only happens when use 600EX-RT on camera, not wireless…confused!

                Thanks Andy,

                I’m not sure if they may be just an issue with your 1D IIIs or not.

                I see you have given up on the RT system though anyway.

                The YN-622C may suit your camera better.

                • Andy 6 months ago

                  Hi FlashHavoc,
                  There is nothing wrong with 1Ds III. The problem is 600EX-RT restricts ETTL in wireless triggering while M is fine. Also, speed sync is 1 stop lower than original sync speed. In my case, 1/250 becomes 1/125.

                  Anyway, the only way to work around is using YN-E3-RT. Unfortunately, my purpose is to use 600EX-RT on camera and trigger YN600EX-RT as the background lights. This is not working, unless i replace my camera to newer model :)

                  So, I’ll stick with YN-622C (already ordered 2 set from Amazon) and hopefully they will work well with 560TX.

  32. tomK 6 months ago

    I kept the one YN E3 RT unit I purchased, but now only keep it in the Emergency bag (in my auto trunk), for the following reasons …

    1. I didn’t find the AF assist light to be as affective as a Canon 600 speedlight for the times I really needed it (wedding reception dancing).

    2. When the transmitter unit breaks signal with the speed lights, both the transmitter AND the speedlight have to be rebooted to reestablish the connection. With the Canon STE3, one only needs to reboot the transmitter to require. Not sure why, and I think I have the latest firmware.

    In my main bag are two STE3’s.

    • Author
      Flash Havoc 6 months ago

      Hi Tom,

      That’s interesting. I haven’t really had to reboot anything to regain a link connection. Usually moving closer to the slave flash restores the link eventually, and its usually restored by the time I reach a slave flash anyway.

      I guess it would help to just switch the transmitter on and off to regain the link without moving position. The other thing I do in this case is to use the auto channel and just do another channel scan. And that generally restores the link again.

      The YN-E3-RT’s limited range is also part of the issue here. I don’t know if that has improved with the latest model though.

  33. michaelv 5 months ago

    I have question for those who has pre-2012 camera that used YN-E3-RT (i have 1Ds III)

    Does YN-E3-RT control both M and ETTL mode for each group? I know Canon ST-E3-RT won’t trigger slave flashes wirelessly in ETTL mode (only M mode).

    I am thinking of getting 4 YN600EX-RT and YN-E3-RT to use at the reception and the event. I want to be able to control different group in either M or ETTL.

    Thanks.

    • Author
      Flash Havoc 4 months ago

      Hi michaelv,

      Unless you’re referring to a specific issue with the 1Ds III, the Canon ST-E3-RT should trigger the slave flashes in ETTL or Manual with pre 2012 cameras. What the Canon ST-E3-RT wont do is allow GR Group mode, where ETTL and manual groups can be mixed.

      The YongNuo YN-E3-RT will allow Group mode with pre 2012 cameras, with ETTL and manual control. Though again I’m not sure if there may be any specific issues with the 1Ds III.

      The range is generally not as good with the YN-E3-RT transmitter though, so you may need to consider having the Canon ST-E3-RT as a back up as well.

  34. Tone 3 months ago

    I have 7 x 600EX-RTs used in three groups via an ST-E3-RT on a 5D MkIII.

    Has anyone tried using the YN-E3-RT on an Olympus OMD EM1 using 600EX-RTs in manual mode?

    I travel a great deal by air to commercial locations and excess baggage costs are becoming an escalating problem (perhaps I should just give up my profession and go skiing).

      Hi Tone,

      I can’t confirm the Olympus OMD EM1s specifically, though this should work with single firing pin and non Canon cameras in general, as long as you use the original Canon 600EX-RT as the slave flashes.

      The main issue at them moment is that this does not work when using the YongNuo YN600EX-RT as slave flashes.

      Yes it is possible. Though you need the amazing little YNE3-RX receivers to attach to each YN-568EX II.

      You can use any of the YongNuo or Canon RT units as master on the camera, not just the YN-E3-RT.

      Do you have another flash etc with an AF light, that is working if you swap it straight over using the same camera settings?

      Things like having the cameras in the wrong focus mode will disable the AF light, it can’t be in AI servo etc. If the issue may be something like that.

    I have a a yn 600 ex rt and a canon 600d. I plan on buying this to control the my 600 exrt remotely. I would like to know if the simple yn 560 iv is compatible with this as both have radio modules enabled. Needless to say i do not expect ttl of it but at-least be able to remotely control the power. pls let me know if this is possible.

    • Author
      Flash Havoc 3 months ago

      Hi Eshan,

      Sorry no the YN560 IV are not compatible with the RT system.

      The most you could do is use a YNE3-RX receiver to simply fire the YN560 IV flash.

      If its just one extra flash you’re after then the most economical and practical option is simply another YN600EX-RT.

      If you were looking to get quite a number of extra remote manual flashes, then it may be worth trying to run 2 transmitter units for both systems. Or just keep the YN600EX-RT for on camera use, and start building a separate YN-560 system for remote manual off camera use.

    UPDATE – June 2015 – I picked up a recent version of the YN-E3-RT transmitter, and the range has improved greatly from the early model I have from last year.

    The YN-E3-RT range now appears pretty well equivalent to the Canon ST-E3-RT when using the original Canon 600EX-RT as the slave flashes. And around 10% or so less with the YN600EX-RT as slave flashes.

    No misfires at all so far within the working range.

    As far as I understand the main update to the YN-E3-RT transmitter was from January 2015 build units.

  39. danikaze 2 months ago

    I think it’s not possible but… can I trigger flashes mounted on the yn-622c with a yn-e3-rt?
    The thing is I already have two yn-622c, and it would be nice having a yn-e3-rt to control them, and the new flashes without needing extra yn-622c using a yn622c-tx///

    • danikaze 2 months ago

      Of course when I say control the new flashes with the yn-e3-rt, I’m talking about the compatible ones ;)
      So it would be something like

      Camera + yn-e3-rt
      C430EX II + yn-622c
      C600EX-RT without transceiver
      YN-560 EX II without transceiver

      if not possible, I would need the following (and safe) configuration:
      Camera + yn622c-tx
      C430EX II + yn-622c
      C600EX-RT + yn-622c
      YN-560 EX II + yn-622c
      but makes me buy an extra yn-622c

        Hi danikaze,

        No, the RT and RF radio systems are not compatible in any way at this stage. So you would need to go with your option 2.

        Otherwise possibly start making the transition to the RT system, and trade your YN-622C for YNE3-RT receivers for your non RT flashes.

    OK, for people having issues downloading from the YongNuo website, I have uploaded the YN-E3-RT firmware update files to DropBox.

    Firmware version 1.18 is now up on the YongNuo site.

    I have also uploaded it to Dropbox here –

    Firmware V1.18
    https://www.dropbox.com/s/rl9r8lhf9djh8vq/YN-E3-RT_FW_V1.18.zip?dl=0

    From what I understand this is mainly a fix for transmitter units built after July 1st 2015. If those units are installed by the user with earlier firmware that will cause an error in the LCD display. Updating back to V1.18 will fix that error.

    So all units manufactured before or after July 1st 2015 can be updated to V1.18.
