YONGNUO – YN600EX-RT Now Available!

YN600EX-RT_300

 

The very long awaited YongNuo YN600EX-RT flashes are now available from around $105 on Ebay, and from the YongNuo Store on Ebay.

Like the YongNuo YN-E3-RT transmitter, the YN600EX-RT flashes are directly compatible with the 2.4GHz RT radio system built into Canon’s own 600EX-RT flash, and ST-E3-RT transmitter units.

 

YN-600EX-RT

 

Features -

 

  • Guide Number 60m (ISO-100, 200mm)
  • Canon RT Wireless Support (Master and Slave Modes)
  • Electronic zoom head 20–200mm
  • E-TTL and Manual Power Control
  • HSS (High Speed Sync) to 1/8000 Second
  • Canon and Nikon Optic Wireless Slave Modes
  • S1 and S2 Optical Slave Modes
  • PC Sync Port
  • External High Voltage Battery Port
  • USB firmware updates

 

Also like the YongNuo YN-E3-RT, the YN600EX-RT flash units provide most of the major functions of the original Canon flash.

And over time there may even be extra functions added. Already Optic Wireless Slave modes for both Canon and Nikon flash systems are supported in the YN600EX-RT flash.

The YN600EX-RT are also YongNuo’s first flash unit available with both HSS (High Speed Sync) functions and an External HV Battery Port in the same flash.

 

YN600EX-RT

 

YN-622C -

PLEASE NOTE - The YN600EX-RT flashes are not directly compatible with the radio system used by the popular YongNuo YN-622C TTL triggers.

Though the YN600EX-RT will still function with the YN-622C system, provided a YN-622C as receiver is also attached to each YN600EX-RT flash foot.

    i have a pair of YN600EX-RTs and i was putting them through their paces and testing all of the functionality. Everything works except wireless optical slave Sc, S1 or S2.

    i am trying to use the built-in camera flash with the them and and they won’t fire. The yongnuo’s are set to Sc, Ch 1 and Group A. The master is the built-in in flash of a canon 70D. The 70D is set to wireless flash enabled, external flash enabled, ETTL, Ch 1, A:B mode and ratio 1:1. I’ve also tried the yongnuo’s in S1/S2 and the 70D in manual instead of ETTL as well.

    Are my flashes defective or do they not support the canon 70D built in flash

    The same camera settings triggers a phottix mitros+ in optical rx mode.

    • Ahmed Agbabiaka 1 year ago

      Nevermind. It was a fluke. For some reason when i tried SC last night, the two leds that indicate optical wireless slave is on weren’t flashing. When i tried today, they were flashing and now the yongnuos work with the built-in flash of the 70D.

      Thanks for playing.

    I just received my first YN-600EX-RT. When using eneloop batteries I get a strange color cast. When using regular non-rechargeable batteries no such issue. Anyone else experience problems using eneloop batteries? I using a Canon 5DIII.

    • Ben 12 months ago

      yes, becasue they dont have the same voltage compared to regular batteries 1.2V vs 1.5Volts.- they also drain faster and heats up faster – I used to have 4 dozen rechargables – now, I just buy 2-3 packs of 36 pack batteries, namely, off brands from Home Depot, they got 1.6volts.

  4. andy 1 year ago

    Question:
    I have 2 5D III. If i have each Canon 600ex-rt on each camera as master ( I shoot dual cameras, by the way), can they trigger slave YN600EX-rt (as slave)?

    thanks.

    • Scott 1 year ago

      You mean third flash off camera? If so, I don’t think two masters can sync to a slave, so one of the cameras could fire the third.

  5. steve 1 year ago

    How do I link the yn600exrt with the yn560tx. This is very hard not liking it

    • Scott 1 year ago

      Don’t think you can. The older one uses the older sync method, the 600ex-rt uses the new RF linking. You can link to the other RT devices.

  6. andy 1 year ago

    to Scott, sorry for late response.
    Yes, I mean each 5DIII has Canon 600ex-rt, and several YN600ex-rt off camera as slave.

    I only to fire master flash on camera one at a time. Based on your suggestion, sound likes it works fine if I don’t shot both master at the same time.

    One question: If i change power level to the slave from one master, then later on i want to change power level of the slave from another master, does it work?

    Thanks very much

    Yongnuo released Firmware 1.8.6 From the change log:

    V1.8.5:
    Fixed:When using the YN600EX-RT and Canon 430EX III together,wireless shooting does not work.

    V1.8.6£∫
    Fixed:Sometimes turning off the YN600EX-RT,the speedlite can not save the setting.

    I have installed this — works fine with Canon 7D MkII — still not with Fuji X100T (see other threads on this)

  8. sal 1 year ago

    Hi,
    someone have user experience about YN 600 ex rt and Canon 5d MK2?
    They are fully compliants or they have limitations: i.e. ETTL, HSS, SCS, 5 GR, Master and Slave functions on RT or Optic pulse, etc?
    I am much confused about pro/cons of this flashes: YN 600EX RT, SHANNY SN 600 C-RT or RF? EXRT or EXRF, Godox TT 685 (or V860?).
    I read each these three flashes have some problems (i.e.
    – hot shoe problem for YN 600 and Godox 865,
    – no optic master mode for YN600 (only radio)
    – unlike godox tt685 that seems actually more complete under this aspect master/slave with both radio and optic functions but seems to have some TTL overexposure problems specially in HSS.
    – Shanny seems to have not hot shoe problem, but no firmware updates availables (though USB is present) and no clear strategy for RT or RF ways: it seems they have stopped the RT develop vs RF).

    I think the best mode for the choice is other’s user experience, because any advanced feature is useless if it does not work on own canon 5d2.
    I need firstly a hot shoe flash with ETTL, HSS, SCS and then a second flash with same functions, whith mix use both ETTL and Manual modes mantaining HSS, SCS, etc.

    I must change my actually old Starblitz 300 DFC (canon Eos) but the camera menu read it as TTL but it works only in manual mode….

    Someone can help me? Thanks!

      Hi sal,

      The YN600EX-RT can not provide GR Group mode with the 5D MKII unfortunately. So you can not have 5 groups, or mix TTL and Manual groups. That is the same situation with the genuine Canon RT speedlites though as well.

      The YNE3-RT transmitter can provide GR Group mode though with the 5DII and pre 2012 cameras.

      The Godox TT685 and Shanny RF flashes currently have basically the same limitation, and using any camera year model.

      The Phottix Mitros+ do allow mixed TTL and Manual Groups though with cameras before and after 2012.

      My personal preference if only needing a few speedlites, and a TTL flash on camera, would be to use a genuine Canon RT flash on camera (600EX-RT or 430EXIII-RT), and just use the YN600EX-RT as remote slave flashes.

      Though you have to live without the GR Group mode then (that’s why I went with a Canon 6D myself instead of the older 5D II).

      Most people using pre-2012 cameras just live with the limitations, as people used the optic wireless system with the same limitation for a long time before that.

      Maybe the Mitros+ will suit you though.

      • sal 1 year ago

        hi,
        thanks for the quick reply and for the advice, I did not know Phottix Mitros+ and I read the flashhavoc review there. As you correctly said,this is a great flash, well built, that best meets my expectations, but unfortunately in version + is more about 3 times over my budget, and in the standard version more than 2 times.

        So I have to get off to a compromise; I try to summarize my needs and my criteria on which the purchase option in order of priority, noting that I have not already other canon flash to drive:
        1. within a tight budget for non-professional use
        2. solid mounting on hot shoe, preferably with quick locking like Canon (except TT685)
        3. compliant with 5d2, but open to future upgrades vs. 6d or 5D3
        4. to use as “first” master on camera, which has especially accuracy on TTL exposure indoor/outdoor with HSS and SCS
        5. to be able to add them (later) a slave radio, initially without an external trigger
        6. The GR group and ttl and manual mix, would put it into the background at the moment, waiting for camera upgrades.

        For this reason I had identified a short list of 3 flashes: Godox TT685, YN600 EXRT, SN 600 EX RF (I think better than RT?) , or low budget SN 600 C -RF (or RT).
        Now for what I read here, were it not for hot shoe problem and af assist issue, I could choose Godox TT 685 or YN 600 EX RT (but not optic master and with same hot shoe issue, perhaps but less important than Godox TT685?)
        For removing the play on YN 600EX RT, have you considered as reliably the solutions showed on you tube through a 30 mm rubber oring? Have you seen this video at link ?
        https://youtu.be/44k-7GY1tuo
        It seems the genial solution but we can see some stress on the lever locking? If this could be a positive solution, a remaining lack of YN 600EXRT may be is no optic master for more flexibility of use (unlike TT685).

        Thanks
        Sal

          Hi Sal,

          I’m not sure if the Godox TT685C foot may have been corrected already or not. In the worst case you could file the front edge down a little yourself.

          I don’t think there is any great issue with the YN600EX-RT foot. The first small batch were VERY loose, though after that they were corrected and I don’t think there is excessive movement. The rubber o-ring is probably a nice idea though as well.

          The real issue is more that the YongNuo and Godox flashes do not have a locking button on the flash head like the Canon flashes, so there is no pressure on the flash foot as you twist the flash head. The Canon flashes are just more refined there. Though if you’re not using the flash for continual professional use its generally not really a big issue.

          You sound like you want to be in this for a while and progress with new gear eventually, so another big consideration I would be thinking about is if you are going to want to include larger lights like the Godox AD360 / II as well? If that’s the case then the Godox master flash (TT685C or coming V860II-C) would really be worth considering.

          We have been trying to get Godox to add the GR Group mode to the TT685C and V860II-C, though I don’t know yet if that is going to happen (and would likely be for 2012 onwards cameras anyway).

          If you just want speedlites then on your budget the YN600EX-RT are a nice option. The best thing there is you can add a genuine Canon flash as the master later if you get more serious about event style photography.

          Personally I have become wary of Shanny and their products at the moment. They have had a lot of failures, and since Amanda left they do not know how to help customers directly. They have just signed Omega Brandness as the USA distributor though, so it may be safer now for US customers at least.

          So personally I would go with Godox if you’re interested in a larger system with bigger lights as well. YongNuo YN600EX-RT if you’re happy with speedlites (and possibly get a Canon master flash later).

          I would also have more faith the Godox speedlites will still be going in a few years. That’s not to say large percentage of the YongNuo flashes hold up well over time as well.

    Does this Yongnuo 600 EX RT work with Nikon D7200?

    • Author
      Flash Havoc 1 year ago

      Hi Atanu,

      Not really as anything more than a basic manual flash when mounted on a Nikon cameras hotshoe. The 600EX-RT are Canon ETTL compatible flashes, not Nikon iTTL.

      If you just want an on-camera TTL flash for Nikon the main option from YongNuo is the (somewhat outdated) YN-568EX.

      If you’re looking at on and off camera flash with radio, then the Nikon version of the YN685 would be the way to go once they are available. YongNuo have mentioned they will be coming soon (likely in the 2nd 1/4 of 2016). They have the YN622N radio receivers built inside.

    We were using yn600 ex RT it for four months but suddenly it started to indicate lock sign with high temperature signal, we tried to release it but we doesn’t able to reach menumenu option , could anyone pls suggest some solution

    • scruff 75 11 months ago

      1. Open trash compactor
      2. Drop flash in.
      3. Close trash compactor.
      4. Press start button.
      5. Walk away.

      I’m not sure about that issue sorry. Probably best to contact YongNuo.

      They do provide 12 months warranty from date of manufacture, though you will need to pay for return shipping to China. (Unless the dealer you purchased from offers a better return / warranty policy).

  11. pwp 11 months ago

    A friend just dropped over with a new Yongnuo EX-RT. We tested it against my two Canon 600 EX-RT Speedlights and at full power the Canon’s consistently gave 1/2 stop more output. Is this usual?

    • Author
      Flash Havoc 11 months ago

      Hi pwp,

      I generally find the YongNuo flashes are all around 2 to 3 tenths behind the Canon 600EX-RT.

      That’s generally the case with many of the 3rd party flashes though.

  12. Ken 10 months ago

    Hi,

    I have purchased three Yongnuo 600ex-rt flashes and I find they all have an exposure problem. I am using a Canon 7DII and Canon 100-400mm f5.6 L II lens for this test with one on camera flash. I am using software ver. 1.8.8 in all three flashes.

    I am finding that all three of these flash units used singly on the camera overexpose by about 2 stops if I shoot a gray scale image that is about 30% of the frame or smaller (subject is a gray fence post) . If I shoot a gray scale image that is 100% of the frame then the exposure is correct. I use the camera histogram to access the exposure.

    I compared the histogram to a YN568EXII and to a Canon 430EXII on the exact same target and both get the exposure correct irregardless of the subject size while the 600ex-rt overexposes 2 stops.

    I have the 600ex-rt set to ETTL mode with 0 exposure compensation for this test.

    What is stranger still is if I turn on the radio control (set the flash to master) then the exposure is much closer to being correct which makes not sense. ( I am not using a slave flash.)

    I also note that all three 600ex-rt flashes report the flash distance range as 1.7-4 feet when the zoom lens is set at 130mm or less and does not change when the ISO or aperture is changed in the camera as it should, but when the zoom lens is set to 130mm-400mm the correct range is shown eg. 10-60 feet.

    I am an electronics technician and experienced photographer. There is clearly a problem with these units.

      Hi Ken,

      I’m not much help as my flashes are still on 1.8.3, and I don’t have a 7DII.

      Though I just tried this with the 7D and couldn’t see the overexposure issue. Its not something others have commented on yet either, so I would guess its possibly an issue when using the 7DII, or even possibly in combination with the 100-400L II (if you’re not having the same problem with other lenses as well).

      Also have you tried changing the flash metering mode from Evaluative to Averaging to see if that’s more comparable to the Canon flash?

      Regarding the ISO and Aperture, yes I see its not changing on the flash scale, though the exposures are still ok (in my case).

      Regarding the radio master, its actually normal for the on-camera flash exposure to drop 1 stop in radio master mode. Though I see the Canon 600EX-RT is only doing this once you have an A:B ratio set, even if its still at 1:1 ratio. Where the YN600EX-RT is dropping a stop in radio master mode even with no ratio set (or “ALL”).

      I would suspect your main overexposure issues are likely specific to the Camera and or lens, or longer focal length used though.

      • Ken 10 months ago

        I have tried changing the metering mode to Average with no change. Indeed I suggest that the problem is that the flash is averaging and not using the evaluative. This would explain why full frame gray target is correct but smaller gray targets which would average less light coming back hence more exposure is the cause. I will try other lens and cameras.

  13. pwp 10 months ago

    Hi Ken, FWIW I’ve always found the ETTL exposures on Canon Speedlights a bit under, and found a default of +1/3 is a good starting point. This goes right back to the old 540EZ. With your Yongnuo’s, I wouldn’t see this as a bit issue so long as they are consistent with the exposure.

    • Ken 10 months ago

      Hi pwp,

      My error is closer to +2ev, I would not complain if it was .3ev. Clearly there is something wrong!

  14. Fritz 10 months ago

    Hi Ken, I’m trying to duplicate your results .I’m not an exact match for setup. but here is mine: Canon 7D Mkii, YN 600 ex firmware 1.8.6, Canon 70-300 L.

    The first thing I noticed is if I point at the subject 20 feet or so away and zoom the lens with the shutter half pressed, at 70 mm the flash reports the right distance range (18 – 60 feet) at 100 mm it switches to 1.7 – 4 feet and then at 135 mm it switches back to 20 – 60 feet. It has the same behavior when pointed a subject 5 feet away.

    Are you seeing any exposure difference at different focal lengths?

    So I can match your set up, where in the frame is your ” gray scale image that is about 30% of the frame or smaller (subject is a gray fence post)”? middle, left, right? (Does it matter?)

    Last what’s the general brightness of the rest of the scene? I was thinking of testing with an all white background and then an all black background…

    Fritz

  15. Ken 10 months ago

    Hi Fritz,

    Thanks for the response.
    I did the test again just now with a gray card. (card is a bit lighter than middle gray but close enough)
    The target was a gray card 15 feet from a gray concrete block wall inside my garage. I used 100mm lens zoom. Lighting was the same on the wall as the target, (basically full shade). If I shoot full frame eg fill the frame with the gray card exposure is correct (hump in the middle). If I then step back so the target is small in the frame eg 25%-30% the width and height then the exposure is 2 stops under. This is consistent across all three Yongnuo 600ex-rt flash units. I got the same result with 200mm lens zoom setting also.
    The Canon 580EXII and 430EXII however produce a correct exposure on both target distances and focal lengths.
    The fact that the flash is reporting the distance info wrong is disconcerting as Canon flash uses the distance info if the target is small in the frame hence little preflash light is reflected from the target but I suspect there is some other issue also.

  16. Ken 10 months ago

    I just tried the same test with a 70D rather than the 7DII body. The 70D produced a correct exposure at both target sizes with the Yongnuo flash units, but the distance info on the flash is still incorrect, suggests there is something different in the 7DII.

  17. Fritz 10 months ago

    Hi Ken, thanks. I hope what I write helps.

    I came as close as I can to matching your set up — my gray card is perhaps a bit dark and instead of concrete block, I have a gray garage door. Similar light on both target and background. and about 15 feet separation from target to background. My frame filled target and stepped back photos were equally exposed as I look at the histograms. I have not downloaded into Lightroom because your difference was pretty obvious to see.

    I am far from an expert on evaluative metering in the 7dMii, but my loose understanding is it gives more emphasis to the zone where focus is. Have you tried switching focus zones to see if it makes a difference?

    Again I’m on the older firmware 1.8.6 and I dont have any experience with the Canon brand flash to compare it too.

    I dont know if you want to try (or if it is possible) to back firmware down on one of the YN600 to 1.8.6 to see if it changes anything.

    Fritz

  18. Ken 10 months ago

    I do not have the older firmware and cannot seem to find it on the Internet. I will continue to test though as I need a resolution.

    • Author
      Flash Havoc 10 months ago

      I’ve only got 1.8.4, though someone will have later versions on their computer somewhere. The actual firmware are only small files.

      I would suspect the issue is probably more related to the 7DII though as you mention, than an issue with current firmware.

  19. Fritz 10 months ago

    HI Ken, here is 1.8.6

    https://dl.dropboxusercontent.com/u/12834410/YN600EX-RT_FW_V1.8.6.zip

    Let me know if you want me to test anything else. I understand your frustration.

    • Ken 10 months ago

      Thanks Fritz, I will try the software today. In the mean time I have set up a page (work in process) with some of my test images. The images are a gray pipe shot at 100mm with a background of concrete block 20 feet away.
      The first two images compare the 7DII to the 70D with the YN600ex-rt flash at 0 comp.

      http://kennewcombe.com/flash comparison.html

  20. Ken 10 months ago

    I tried going back from firmware 1.8.8 to 1.8.6 but the result was the same. The amount of over exposure on the gray pipe test is about +1.7Ev with both firmware versions.

  21. Ken 10 months ago

    I tried using two other lens, a 100mm Canon macro and the 18-135mm zoom with the same over exposure result. The most revealing test today was using the Canon 580 ExII and switching the 7DII menu item, Flash Control, ETTL II metering from Evaluative (default) to Average. The image exposure was now identical to the Yongnuo 600ex-rt. That is they were both over exposed by the same amount. This is expected behavior for a flash averaging the light value when the subject is small in the frame with a distant background. It appears to confirm my thought that the Yongnuo is not using the Evaluative metering but is still Averaging even when set to Evaluative. Probably a software over- site that was missed in testing.

  22. Fritz 10 months ago

    Ken, I think you have your answer — and also, let me share an observation — but maybe it doesn’t matter. In your 70 D example, you are in ONE SHOT, and in the 7D you are in AI Servo. In an old thread about the original 7D

    http://www.dpreview.com/forums/post/37463930

    There is discussion about evaluative metering in AI servo and how focus is determined. Could this also play a role? You have more flash experience than I do, my test shot (at 166 focal length) is here.

    Hi guys,

    Probably I had used my YN600 too extensively in wedding so now my speedlight is dead. When I switch it on, it shows the overheating symbol and it does not go away for months. I got it working for few minutes after cooling it down placing it in refrigerator :-) and use this lucky moment to update firmware first to 1.8.6, then to 1.8.8 version. No success, same overheating symbol. I saw in changelog that in older version 1.8.1 there were some fix to that but it seams to me that it is not fixed. Took to local repair, the man there said that all the electronics is ok but controller is sending this f.. overheating symbol. Does anybody have any ideas? Or You had the similar issue?

    to Gundars & others firends have this YN600exrt problem : i have the same problem, i have May 2015 batch, firmware v1.8.5 ( currently after a job use , it show up heating icon!!! , can NOT use or flashes, just freeze like that. try update firmware to v1.90, no luck, the problem still there….

    i brought it on online @Taobao, email them : hkyongnuo, no reply..

    anyone can please help here..?????

      Hi shutterboy and others having overheating problem on YN600:
      I got an e-mail reply from Yongnuo guys, they said (as always): put newest firmware, if it does not help most probably your speedlight is dead. As I wrote, my local technicians said that electronics are ok, so.. I guess my 120 USD are gone.
      I did not try firmware 1.9x but I feel it is waste of time…

    Hi, I am after some advice, I have the yongnuo triggers yn-622C (I am using a Canon 6D) and I would like to trigger them from an on camera flash without having to put another trigger under the on camera flash. So is there a flash unit that is compatible and also has an external power port and will do HSS? It seems that even the Yongnuo 600EX-RT isn’t compatible unless I mount a trigger between it and the camera, is this true? Kind regards, Steve
