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.

UPDATE – FEB 2017 – The YN600EX-RT II are now available.

 

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’ve had one on order for a month and it looks like it just hit customs. I already have 5 600-EX-RT plus both the Canon and Yg triggers. I’m hoping I can add a few more flashes to my arsenal with these, Hopefully they will be reliable.

    yep, in french! Waiting for a proper review.

    The company I ordered changed the estimated delivery dates twice and the first email they sent me was in short: ” we will send you you order asap”.
    As soon as i saw that I filed a claim with Paypal and they got my money back immediately. The second email gave me an excuse that they were waiting on another customer to send a flash he was not happy with to fill my order! I don’t know if it was someone with a poor grasp of English or it was what he actually meant to imply !
    On their Ebay listing they say they have 5 available and 15 sold and the estimated delivery is between Nov 25 and Dec 10th. That was the 3rd estimated delivery dates. Also the price is quoted at 250.00. That has not changed. – See more at: http://flashhavoc.com/yongnuo-yn600ex-rt-now-available/comment-page-1/#comments

    Got mine yesterday, works great, behind walls etc. over 100 ft range. I am happy

  5. Ben 5 years ago

    What voltage does the external battery port have and how many ampere does it need? I’m thinking about using power cables for the flash.

  6. Jse 5 years ago

    Hallo, i looked for the yn-600ex Rat but it seems not to be available? Soldat out???;-)

  7. morow 5 years ago

    Got mine today, the build quality is not the that great, the ETTL is not that accurate. From 10 shot I am getting one overexposed. It is little bit wobbly on the camera, is not wobbly when is on the “foot” from Yongnuo. Didn’t get time to testing it off camera. It’s for sale now.

  8. Adrian 5 years ago

    Ok, I have mine in hand but have not done a full trial yet.

    I can say that I love the fact that they took away the need to push a button to swivel and or tilt the head. That button is a pain.

    I also really like that there is a battery meter. I mean, come on Canon, we are pros and we need to know if the batteries in our flashes are low or full.

    Now for the disappointments. TTL does not work in group mode on pre-5dMKIII cameras. All channels instantly switch to M as soon as you half press the shutter button. That is actually a downgrade from the Canon as you can get off “one” perfectly working shot with the Canon 600 EX RT before it realizes what camera it’s on and takes you out of group mode. You can turn everything off and back on and take another shot time and time again, you just have to “reset” between every shot.

    I also did some quick tests on a 5d MKIII and everything seems to work fine in all manual mode. There are problems in ETTL while in group mode though as the Master (the YN flash) fires witht he camera and then the slave flash (Canon) fires a few seconds later.

    I am thinking or possibly hoping that there is a problem with mine. I will test it more and if it is faulty, return it (I hope).

      Thank Adrian,

      I’ll give this a try as well.

      I don’t really agree on the flash head button though. Did you notice how the YN600EX-RT twists in the camera hotshoe when you try to swivel the flash head?

      If there was a button like the Canon flash, at least there is no pressure needed to swivel the flash head, even if the flash foot is a bit sloppy.

      For off camera use its not really an issue.

      Hi Adrian,

      I can confirm the Group Mode only works in manual on pre-2012 cameras. This appears to be intentional though. It would be a major bonus if it did work in ETTL as well like the YN-E3-RT.

      I’m not sure about the ETTL and Group Mode on the 5DIII as I haven’t been able to try on that yet. This could well be something to be addressed with firmware.

      In general the flash appears to be working very well with the RT radio so far though.

      Also regarding the loose foot in the camera hotshoe, it does have quite a bit of side to side movement, but the clamp does actually stop the flash from tilting forward like the YN-E3-RT or Pixel Mago, so it may not be as much of an issue on camera as I had expected.

  9. Adam 5 years ago

    Any clue when the Nikon users will get an updated flash from Yongnuo that has both high speed sync and external battery port?

      Flash Havoc 5 years ago

      Hi Adam,

      I would hope they are working on a similar 600EX style flash but with YN-622N transceivers built in. But I really don’t know what they actually have planned there.

      Shanny already have the SN600N for Nikon for just $92 shipped though. And the SN600SN to come soon. They both have HSS and external battery port.

  10. Mithilesh 5 years ago

    Are these available in Amazon? I want to get these : )

  11. Yuppa 5 years ago

    @morow

    You can get variances in TTL with the SAME subject, SAME settings, SAME distance…same EVERYTHING. TTL is computed EACH time the flash if fired and is controlled ENTIRELY by the camera’s meter. The only acceptable way to test flashes comparatively is in manual mode ONLY.

    • morow 5 years ago

      You should see what the Pixel X TTL flash was doing on camera, the exposures were all over the place, I don’t think that was the camera issue. I’v had few Canon 600’s and the exposures are more less accurate. Still think it’s not a bad value for the YN 600 flash. If I need manual flash I prefer cheap YN 560’s.

      • Yuppa 5 years ago

        My point–going to your other post–was that 1 miss out of 10 is actually good for TTL–it’s not infallible!. The camera controls TTL, but that doesn’t mean there isn’t an issue with the flash translating those singles. If 90% of my TTL flashes were correct (which can be subjective), I’d be hard pressed to blame either the camera or the flash.

        I will just have to buy one and see for myself 😉

  12. kevin 5 years ago

    can the yn600ex-rt work in ttl in group mode when it’s off-camera provided i’m using a yn-e3-rt to trigger it? i can’t wait to order mine once it’s available here locally in my country

    i’ll be using it on a 7d

    • morow 5 years ago

      TTL in Group is working with YN E3 RT (5D MK3)

  13. Denton 5 years ago

    Got mine, seems to work OK in Group Mode which is what I need (after I remembered to change the channel lol). This is with the Canon controller btw. I paid $188. I really wanted a pair but wanted to make sure it worked before I ordered a second one. However the price seems to have gone to $250 meanwhile. I think I’ll wait and see what happens. The manual is in Chinglish btw

  14. Ryan 5 years ago

    Seems like the demand is high and supply is non existent right now. Thinking about picking up two of these for remote flash at weddings. Any ideas when they will get restocked?

    • Yuppa 5 years ago

      They’re to be had on Ebay right NOW…for double, triple, quadruple the price.

      • Ryan 5 years ago

        Yeah I’m thinking normal price 🙂 Maybe at the official store! For that price is buy the canon version!!

        • Yuppa 5 years ago

          Yep. I personally don’t buy ANY Yongnuo products unless they are on Amazon and the ITEM is fulfilled by Amazon (buyer protection) with Prime shipping. I have a feeling I will be waiting awhile for these.

          On Ebay, I’ve seen listings as high as $800.00, as if they have NO clue that this is a Canon knockoff and it’s “parent” is ~$500.00.

    whats the AF assist beam like on the YN 600 ex in very low light? I know my YN 565 is redundant if its any way dim 🙁

      Hi John,

      The initial batch sold out pretty quickly, though they were available for a couple of weeks.

      There seems to be some delay in the second batch, so I’m not sure how far off they are now. Prices were around $180 even in the official YongNuo store, so there should be no reason to pay more than that once stocks are available again.

      • Ryan 5 years ago

        Flash Havoc,

        I saw on this video that a reseller told the reviewer that there were some issues which caused them to stop production. Since then he has got word that production started again 2 days ago. Have you heard from any of your contacts any details on this and or what the issues were?

        http://youtu.be/wcs5qyY-Fj4

        • Author
          Flash Havoc 5 years ago

          Hi Ryan,

          YongNuo and others always do a limited first production run so that they can address any issues that may arise before starting larger production. So I don’t think there is much out of the ordinary here, its just taken them a while to address whatever was needed.

          I have 2 YN600EX-RT and they are working great so far. I’d love to think they would be improving the foot so that its more secure in the camera hotshoe, but I wouldn’t count on that happening.

          I would agree with what the reviewer said, these are mostly ideal inexpensive slave units to complement a genuine Canon 600EX-RT on camera. The YN600EX-RT still functions ok on camera, but as a slave where the flash foot and connections are irrelevant is where they are ideal. They appear to have better range, and recycle faster as many third party flashes do now.

          There are none available at the moment, we just have to wait for the second production. We won’t know when they are really ready until they are actually shipping to dealers etc.

  19. Yuppa 5 years ago

    @John,

    All you can do is bookmark the Yongnuo Store @ Amazon and check it every four hours or so–sorry, “them’s” the breaks. When i posted the availability of these, they were in stock for about six hours–seven of them. So they were there for the taking for some time.

    I paid $178.99 with free two-day shipping (I have a Prime account) and you can’t beat that on Ebay–no way!

  20. Yuppa 5 years ago

    Has anybody updated the firmware on theirs yet? How did it go? I have been unsuccessful thus far. I have had NO issues updating my YN622C-TX.

    From what I’ve seen thus far, it’s one heck of a flash. This issue I have is I’m running firmware 1.3 and it’s up to 1.7 on their website, so I’m missing out on some key fixes.

  21. John 5 years ago

    Maybe in the next batch they might fix some of the concerns mentioned by some buyers, loose hotshoe etc.,.

  22. Yuppa 5 years ago

    The easiest thing to fix is the foot issue, but NO.

    They must have inventory to burn through first. With a twist locking ring, you can at least minimize the play. But with Canon’s quick lock, nope–it’s worse.

    Too bad: this is a silly thorn in their otherwise outstanding line for sure.

  23. Yuppa 5 years ago

    i don’t get it. Why waste so much time trying to duplicate the ULTRA complicated/sophisticated Canon 660EX-RT when they just could’ve released their OWN (copied 580/430 EX) flash compatible with the 622 system?

    They did it with the 560 series:

    560 III = built in receiver.
    560 IV = built in transceiver.

    Come on Yongnuo: give use a straight forward TTL/HSS flash–like the ones you offer that work reliably–with the 622 system radio BUILT-IN.

    AND FIX THE LOOSE FOOT ALREADY!

    • doood 5 years ago

      Ugh. I think you might have just burst my bubble. Does HSS only work with the YN600EX-RT when it’s on camera?

  24. Jamesy 5 years ago

    Is there a v2 of this flash shipping yet with a fix for the foot issue?

  25. Jamesy 5 years ago

    It looks like eBay has stock of these flashes again – all around the $178 U$D mark…

    • Author
      Flash Havoc 5 years ago

      Thanks Jamesy,

      Looks like they are back in stock in the YongNuo Ebay Store as well.

  26. John 5 years ago

    Yongnuo need to make a statement regarding the loose foot issue and whether a new fixed batch has been produced. If a product is deemed faulty, its irresponsible of a company to continue selling it. Otherwise, will probably wait for the YN 600 EX RT FF (Fixed foot) model.

    • Author
      Flash Havoc 5 years ago

      Hi John,

      YongNuo have been using the same size foot on their flashes for years now, so I’m not sure they would even agree that there is an issue.

      The Shanny flashes are quite secure in the camera hotshoe though, so a little bit of competition may hopefully see YongNuo give this some more consideration eventually.

      If anyone does see a difference in latest YN600EX-RT foot please let us know though. Thanks.

  27. John 5 years ago

    Any reviews of the AF assist beam in low light?

  28. Yuppa 5 years ago

    From what I remember, the AF on the YN600EX-RT was as crappy as any of my other YN products:

    1. It’s too high.
    2. It’s too spaced out.

    The BARE minimum requirement of ANY A/F assist light is that it work flawlessly with the center A/F point (other points are icing on the cake).

    YN doesn’t meet that requirement. Pity.

  29. John 5 years ago

    Damn, that was the decider for me. If you are doing nite club photography in low light and you can’t focus on the person 2-3 foot from you, then there’s no point . They need to improve the AF beam, up to the level of the canon 580 ex2!

  30. Yuppa 5 years ago

    Sorry for not providing more to help you decide:

    Here’s my situation. I have a 60D and use the center point almost exclusively. The YN A/F assist light is VERY focal length dependent. Wide, it’s tight (albeit too high): the center point works by catching the bottom 1/4 of the pattern. But around a mere 55 mm or so, it becomes unusable as the gap between the lines is simply too wide.

    If you have a body full frame sensor or a larger center A/F point area, or you can expand your center A/F point a bit (the 60D’s points are too far apart to make that practical for me), you “should” be OK.

    If you don’t need radio right now, I’d go with the Shanny SN600SC. I’ve got one and I’m quite impressed. It’s essentially a Canon 600EX (the non-RT model). You will be able to add-on radio via a receiver module (available early in 2015). The SN’s A/F assist light and pattern are certainly worse than Canon, but it’s better–with crop sensor 60D–than Yongnuo’s pattern.

    • Author
      Flash Havoc 5 years ago

      Yes the focus light is generally ok if you’re using the center focus point, and reasonably close to the subjects, but not too close within a couple of feet (or the AF pattern may be a little high).

      Though my main concern with the YN600EX-RT for on-camera flash use would be the loose foot anyway. We’re yet to hear if the latest version have made any improvements there.

      Shanny have also appear to have mentioned they may have a new AF module more like Canon’s. We should see next week if that is the case.

    Hi I’m wondering if anyone can give me the dimensions of the flash head or if it is similar in size to the 580 ex ii canon ?? I have a coco ring flash adapter similar to the ray flash that I am wanting to use it with ..

    • Author
      Flash Havoc 5 years ago

      Hi Bianca,

      They are slightly different shapes. At the widest points the YN600EX-RT are 79mm x 51mm, while the 580EX II are around 76mm x 50mm.

      So the 600EX-RT stofen style caps will not fit the 580EX II, though if your ringlight has a little extra tolerance that may still be ok.

    Is their any alternative close in price ?
    Why not just buy the pro foto b1 since they now have hss? Or ? Errrrr help! Why isn’t their a speedlite system that uses lithium ion batteries with hss off cam wirelessly ? Should I just get a paul c buff einstein or are they a pain to carry ?

      Hi Jason,

      YN have not stopped production, the second production run of YN600EX-RT are available now.

      Shanny are the other coming alternative, and the will have a flash with RT radio slave mode only in a few weeks for around $130 (the SN600C-RT).

      There are Lithium-Ion powered speedlites with HSS available with Godox V850 and V860.

      The Einstein and VML are very large to lug around compared to a speedlite, but that is why the Godox AD360 are very popular now. You can still fit on in a regular camera bag if needed.

      The AD360 are also Lithium-ion and HSS enabled. TTL models will come next year.

  33. Donald 5 years ago

    I have both the Canon 600EXRT and Yongnuo 600EXRT… does anyone have this problem as well?
    The Canon version can LOCK at 90/45/180 degrees and you need to press the side mechanism to change the orientation.
    The Yonguo version has the side mechanism but maybe it’s just for visual, with some strength I can just move the orientation 45/90/180 degrees manually… it doesnt need for me to press the side mechanism to change

    Is this normal?

    • Author
      Flash Havoc 5 years ago

      Hi Donald,

      Yes this is normal, there is no button lock in the YN600EX-RT head.

  34. Donald 5 years ago

    I read a review on another website and the previous comment I had can be confirmed normal. I have one question left about quality control… does the SEL/SET button on the Yongnuo 600EXRT move around when rotated or freely when touched upon? The Canon one doesn’t, but the Yongnuo does. Thanks.

    • Author
      Flash Havoc 5 years ago

      Hi Donald,

      If you mean the SEL/SET button rotates with the dial, then yes that is normal.

      I don’t think its any practical issue though is it?

  35. Donald 5 years ago

    Sorry, another question. I have 2nd batch of Yongnuo 600EXRT and it BEEPS everytime it recycles… the Canon one does NOT do this… how do I turn it off?

    • Author
      Flash Havoc 5 years ago

      Hi Donald,

      I only have a couple of the first batch here, but if the the second batch is the same, you just set custom function 20 to OFF.

      I have a question for you though, does the flash still have quite a bit of movement in the camera hotshoe if you twist the flash from site to side like you were trying to swivel the flash head? Thanks.

  36. Donald 5 years ago

    Hi,

    I don’t know what the hotshoe issue is about but guessing from what I’ve read about I’m guessing the bottom half the flash is literally twisting on the Yongnuo version when you twist the top head. I put the Canon and the Yongnuo one on my hotshoe and and twisted both of the heads normally; the bottom does not twist on the camera hotshoe. There is tiny slight movement but that is same with the Canon version I have.

    • Author
      Flash Havoc 5 years ago

      Ok thanks Donald.

      That’s a good sign then that YongNuo may have modified the flash foot on the second run YN600EX-RT. Thanks.

      The first run and previous YongNuo flashes have all had a smaller foot than Canon flashes, so you can twist and basically rattle the flash in the camera hotshoe.

      Hopefully someone will eventually be able to measure the width of the foot with some vernier calipers to confirm the foot has been updated.

      • Donald 5 years ago

        I dont have the tools to measure it but I just held the Canon and Yongnuo versions side by side and the metal foot seems to be the same size; I dont have the first batch so maybe this is inaccurate. The metal foot on the Canon is slightly thicker but length and width wise both versions are the same

  37. Donald 5 years ago

    A big difference to note for me at least between the Canon and Yongnuo version is that the Canon version will beep ONLY when it actually needs to recycle so if you’re popping 1/1 full power shots you will hear the beep but if you’re popping 1/128 power shots you won’t hear it. The Yongnuo version beeps after every flash pop, no matter what power it is shot at.

    I can see why Canon would program it that way though.

    • Author
      Flash Havoc 5 years ago

      Ok thanks, yes I see the same result. Where you able to turn the beep off ok?

      This is a bit annoying for on-camera use, hopefully YongNuo can possibly revise this.

      • Donald 5 years ago

        Yeah, I am hoping they can fix this through a firmware update.

  38. Donald 5 years ago

    By the way I just found out that you can find out when your 600EXRT was made; just twist the head 180 degrees and there will be a sticker somewhere with the date check off.

  39. Doug 5 years ago

    Any idea if there are plans for any manual triggers to bring both studio strobes and Yongnuo’s other products into this mix?

    I keep looking for the best system to buy into, which so far from compatibility looks to be Phottix, but from price Yongnuo and now Shanny look interesting, they just need compatibility.

    • Author
      Flash Havoc 5 years ago

      Hi Doug,

      After much harassment Shanny have said they would intend to produce an RT receiver unit for other manual studio lights etc by around mid 2015. I wouldn’t rely anything definitely happening though until they are actually available (as they have changed plans many times already).

      I haven’t asked YongNuo, because as we have seen, even if something was already developed it could still be another 12 months or more before anything is actually available.

  40. Brian 5 years ago

    I am new to using flash, besides renting a 600 ex rt to use on my hot shoe for indoor sporting events… currently I have a 1 dx for sport events indoors and want to expand into portraiture and looking for a system where i can get a trigger on my hot shoe and 2 flashes off camera radio- triggered-….Even if i ordered YN 6000 ex-rt they won’t ship till january, all the review s here and elswhere appear to indicate that the Shanny will be better than YN’s version and even better than C’s version?

      Hi Brian,

      I wouldn’t say the Shanny gear is better or even comparable quality to Canon’s, though still quite decent considering the price difference. Apart from the lower resolution LCD screen the Shanny flashes appear to be built a little nicer than the YN600EX-RT, though we have to see yet how reliability goes over time with either. The SN-E3-RT is being revised before full production starts.

      As far as features, YongNuo have been able to engineer in some extra features in the YN-E3-RT, where Shanny have just simplified the interface and added he LCD screen. Also added the optic wireless master if that is of interest. But in general they have not engineered any new features as yet.

      The SN600C-RT with RT slave mode only should be available in January. The full SN600EX-RT may be available late February before the Chinese Spring Festival. If they don’t make it before the holiday than it could possibly stretch out to March – April etc.

    how about a speedlight or other studio strobe with TTl and HSS with radio transceivers/receivers with option to plud into the wall and or use Lithium ion batteries?!?!?

  42. Micke 5 years ago

    Hi!

    Got my YN 600 EX-RT yesterday, I already have two of the Canons EX600’s and I must say they are very similar. The Yongnuo seems to function as good as the Canons, however the Yongnuo drains the batteries overnight. I put new batteries in the flash yesterday and had to replace them in the morning. I only fired a few test flashes. My Canons don’t have this issue.
    Maybe this is due to old firmware in the Yongnuo. I tried to update the firmware, but the update software is not working properly. I’ve tried several times without success on my pc. My main computer is a Mac and I really hope we will se an updated version of the Firmware update software for OS X soon!

      Thanks for the feedback Micke.

      I haven’t noticed the battery drain issue, but will put fresh batteries in tonight and check this tomorrow.

      Was the flash switched off, or in standby / sleep mode?

      • Micke 5 years ago

        The battery drain happened even though the flash was shut off. But it’s doesn’t happen all time, only occasionally.
        I’ve still not got the firmware update to work, probably because I’m using 64 bit windows as stated in another comment below.

        My unit has Firmware 123 and the date is 2014-12-08, maybe I already have the latest firmware. The serial number of my unit is 66000770, does anyone know if this is the first batch or the second (or else)?

          Hi Micke,

          I’m not sure about 66000770, my 2 flashes from the first batch are 66000013, and 660000217.

          My original firmware are just stated as 2 and 1 3.

          Is the flash very loose in the camera hotshoe? If not its likely the second batch.

  43. Jamesy 5 years ago

    I would be interested to hear from someone who picks up a version 2 who already has a version 1 in order to confirm the hotshoe issue has been fixed.

    Thanks in advance!

      I would be very interested as well. Or if anyone with the latest version can measure the foot width with some vernier calipers, that would answer the question as well.

      I have 2 of the first version already, so I’d prefer not to buy another just yet.

    as soon as the shoe is fixed, we now have a battery drain issue! ??

  45. Howard 5 years ago

    My two units arrived from China two days ago

    I have the battery drain issue too

    Leave batteries in the units overnight and next morning they are completely flat. Tried both alkaline and rechargeable.

    Units were left out of the cases with the power switched off

    Just waiting to hear from seller – guess they may be heading back to China

    I have the 2nd version, testing the battery drain issue now… will report tomorrow

    • Steve 5 years ago

      If you look in the manual in the basic functions Part 2 you will see at the end that it says to take out the batteries after turning off the speedlite. Maybe they knew about this issue from the start.

      • Yuppa 5 years ago

        From page 2:

        “Please take out all the batteries if not use this product for a long time.”

        The restatement on page 15 might be a translation issue.

        • Steve 5 years ago

          Looks like to me the statement on page 15 was a better English translation than page 2.

    Hy Flash Havoc
    I have Nikon D7100, which one is the the best for me yn568ex or yn600ex. i used in mostly portrate and wedding field.

  48. Howard 5 years ago

    Interestingly, when I sent them back the ebay seller implied that the batteries should be removed every time the flash is turned off and this was from Yongnuo.

    I told them this was unacceptable as it made them unusable – especially given how quickly they drained when left in (but turned off)

    We shall see if they try to take this position when they arrive back in China

    • Yuppa 5 years ago

      It seems to me the ball is clearly in Shanny’s court right now. If YN actually expect us to take out the batteries after each use–when this isn’t true of ANY of their other flashes, let alone the competition–then they’re out in my mind (even though their distribution is VASTLY superior to Shanny at this point).

      I’m excited about Shanny’s up and coming RT (Canon) and RF (their proprietary system) triggers and flashes–we’ll have to wait and see. My SN600SC has be flawless so far.

  49. Donald 5 years ago

    Sorry for the late report. Since my last post 4 days ago I have left Eneloops in my Yongnuo 600EX 2nd run version with FW 123 dated 12/04/2014 and the battery is still good… I even popped 1/1 power bursts to check. Must be just yours or your battery… =/

    I have spent half a day working out how to update frmware on this unit. Just to save others the pain the current setup file doesn’t run on x64. You need to find a 32 bit windows 7 (confirmed works) to get the setup to work.

    I did the update on the 30th Dec 2014 and upgraded firmware to version 123 (not sure if it was version 123 before but these steps should help others regardless

    1. Download setup app http://yongnuo.com.cn/app/YN600EX_Update.rar
    2. Download firmware http://yongnuo.com.cn/app/YN600EX-RTFWV1.8.rar
    3. Run the updater software and click driver. It will prompt you to install the driver. If it doesn’t you have some issues and I would suggest trying it on another computer.
    4. Then follow the instructions in the word doc which are in sequence (Open > File – you will need to browse for the hex file in the rar you downloaded previously > Update. This will update the camera flash and you can confirm this by looking on the flash screen. Once the update starts the computer will tell you USB device not recognised.
    Once the update is finished you will see “Update complete please reset” on the flash screen.
    Pull out the usb connector and turn off the flash
    Turn it back on and go to C.Fn 27 and you will see Version Query. After installing firmware update 1.8 the flash itself shows firmware version 123 and timestamps the system with the date it was updated.

    I have sent an email to Yongnuo to ask that this is correct (flash showing FWV 123 and will let you know if this is correct. If it is incorrect I guess it is back to the drawing board..

    • Yuppa 5 years ago

      The firmware update nonsense–not to mention my flash would NOT turn off–is a big reason I sent it back. The updater DOESN’T work on x64? YN, are you kidding us? How will we know when that gets fixed? I’m not touching another one of these until I know for sure:

      1. It DOES turn off when I turn the switch to, “OFF”.
      2. The firmware updater works flawlessly on x64 machines (like their trigger updater does).

      These have been available on Yongnuo’s official Amazon store for SOME time now (currently @ $180.00). They don’t seem to be moving.

      • Donald 5 years ago

        This is the 2nd batch Yuppa… they probably made an abundant amount. The first run batch was limited supply and there was no stock for a while causing sellers to raise the prices to $250 ish range.
