Does this work with the 430 exiii-rt?

  • I just got this unit (Feb 2016) after contacting Yongnuo..the latest firmware is needed but it does now work fine w/ 430 RT. Just make sure you set the ID to match and also set the channel to auto.

will this work on sony a6000 with the yongnuo yn600ex-rt? I have a cheap trigger but need to adjust the power of the flash, have the adapter too

  • It will ineed, however, if you have the black model of the a6000 and not the silver, you'll need to remove some of the black paint from the metal on the hotshoe to get it to trigger.

Does this work with yn-622c to control an older canon flash like the 580ex for ttl mode?

  • Hi Ka Chun Wong, our YN-E3-RT can work with YNE3-RT to control Canon flash 580EX for TTL mode, not with YN622.

    Bought this to replace Canon's ST E3 RT which does not have IR Focus Assist for some dumb reason they took it off. Anyway this Yognuo has the IR and works perfectly. if your hands hurt at the end of the day and you are tired of keeping your flash on-camera during low light the wedding receptions get this one instead. ///////6MONTH Update: Product seems to work fine but display backlight seems to have failed which is quite frustrating in the near dark of a wedding venue. I am hoping there is warranty service available.

    Quite impressed with this unit. Has worked flawlessly with the Yongnuo flashes I also purchased. Bought these when my faithful 580EX took an unexpected fall and quit working. The build of the wireless controller is great and it was very easy to get up and running. Also have some other Yongnuo wireless triggers and while they work well, it seems the buttons to switch channels get bumped often and you have to change them back to the correct channel frequently. The YN-E3-RT doesn't have this issue at all. It just works. I use this mainly for portraits on location triggering multiple flashes on light stands with soft boxes.

    Just adding one more confirmation, without firmware update it did not work with my 430ex III-RT at all, but after firmware update it's working perfectly with my 430ex III-RT (III has wireless, unlike II) I had to download two programs from the yongnuo website (I downloaded them onto a virtual machine so no virus/malware could be on my main one, it's often a bad idea to install obscure chinese software on your main computer), plugged device into usb and updated the firmware on it. 5 seconds later it was perfectly controlling both my 430ex III-RT wirelessly just like the official device, and for something like a quarter of the price. A few minutes of extra work is certainly worth saving three hundred bucks in my own opinion. Though the real drawback is I've heard if the device does malfunction sometime in the future, the cost of shipping to china, questionable repairs and wait time may make it easier to simply buy a new one. Of course, if the alternative costs as much as 4-6 yongnuo transmitters, it's hard to be mad about eventually having to buy a single cheap replacement or two.

    Surprisingly this transmitter works as well as the Canon... and it has the AF assist beam which is huge for dimly lit wedding receptions. The reason I didn't give it 5 stars is because the range isn't as good as the Canon's, and the scroll wheel is a bit finicky. Otherwise, it looks and works just like the much more expensive Canon version. As is the case with most aftermarket replications, it doesn't work 100% like the original, but does the job... and even gets the shot where the Canon cannot. Edit: After almost a year of use, we grab the transmitter before we do the Canon. The reason being is the AF assist beam. While the scroll wheel will drive you crazy at times, once you are setup, you don't have to touch it again. What does matter is getting the shot, in which the Yongnuo will do a better job of. If we're out in the field in bright sun, we'll take the Canon, but more times than not, our flash work is done in dimly lit reception halls. Pros - AF assist beam - Cost.. which can be huge Cons - Cheaper build quality - Scroll wheel - Reduced range - After market firmware isn't guaranteed to work with newer devices - Foot mount doesn't seem level or perfect fit While the cons list is larger than the pros, this receiver is simply a better buy than the Canon one. The price of the AF assist beam is worth a lot.. and considering its cheaper than the Canon... its almost a no brainier. I would start out with this receiver, and add the Canon to your kit if you're finding that range is an issue.

    Exceptionally well built, but does NOT work with their 560 III or IV or 603 RF triggers/flashes. Otherwise, just as good as Canons, perhaps better?

    Ive had this for about a month now and I love it compared to what I use to use, which was just some cheap wireless triggers off of ebay. I have been using this to control my Canon 600ex rt off camera outside on location in 32F give or take weather. The range is great, I have not exceeded the range of this. Power consumption, I got about 400 shots before the two rechargeable AA's died, so not bad but not great. The display has gone bezerk a few times, but keeping in mind I am using this in freezing conditions, hopefully that wont happen during the summer. And when it gets really cold the screen is slow to update as you change the power settings. This seems to be worse in manual mode than auto. My only problem is that the power adjustor is hidden in the manual mode, you have to press a few buttons before you can change the power, it should be on the home display. ETTL is a bit easier to adjust the power, you only have to press one button instead of a few. Other than that, this is a great device, well worth the $100.

    Although I did not purchase this particular product from , I do own it and use it regularly. The YN-E3-RT is compatible with Canon Speedlites that have built-in wireless remote capabilities. This list includes the 600EX and 600EXII series, the 580EXII and the 480EXIII series. It also works with the YongNuo YNE3-RX wireless flash receiver. For all other Canon compatible speedlight units without wireless remote, the RNE3-RT receiver will allow these speedlites to be used wirelessly. The ETTL features will also be available if the speedlite has this capability through the hot shoe. The only reason for the 4-star rating is that this trigger has a wonderful feature not found on the Canon or other flash triggers compatible with Canon. that feature is that the YNE3-RT has an Auto Focus Assist Beam. When it works, that is. I have contacted YongNuo and their reply is that this is a known issue and they are working on a firmware fix. If they fix this, I will change to a 5-start rating. I must comment on the AF Assist on this unit, it is not just a blob of light transmitted , but a pattern of crosses that the auto focus in the camera locks onto quickly. Canon, take note, this is a much needed feature!

    I just got one directly from China. It took 10 days to be delivered, but it was 25% cheaper than what I could get delivered in 2 days from Amazon Prime. It came preloaded with the latest firmware version: 1.14 (on their website, today, they only have 1.13 for download) It works flawlessly with my original Canon 600EX-RT. Despite what I read on the previous reviews, mine fits perfectly on the 5Dmk3 hot shoe. I don't see any difference between the original Canon flash and this trigger.

    I needed a cheap but working solution to wirelessly fire off 3 flashes. I looked at canon ST E3 RT and while its nice I found it to be expensive. I then did some research and found the YN E3 RT. At first I was hesitant to make the purchase because I read reviews how it would work for a couple of days then stop. Well I just got down taking 435 photos and the flash popped off every time. So maybe the other people got a bad copy? Only downside about this is that you need to perform a firmware update for it to work with the new Canon 430ex RT III. Also, you cannot do the update from the Mac.....It's PC only. Other than that I am happy with the transmitter,

    Bought this for use with my Canon setup but didn't want to pay the big bucks for a Canon remote flash trigger. Works perfectly. The only downside would be the instructions - not very clear. But don't fear there are plenty of helpful forums on the internet and you tube videos explaining how to use this. Not to mention it is fairly straight forward if you know how to use a flash. Product was exactly as described and worked perfectly. Even looks almost identical to the Canon version that is at least $100 more.

    Works Perfectly with my Canon 60D and Canon 600ex/rt speedlight. I think I will purchase one of their equivalent flashes (to the Canon 600) as as second light, since it has worked so well.

    Completely happy with this. Handles multiple flashes -- Yongnuo 600EX-RT, performs as advertised and allows me to control off-camera flash from the camera. Works great! They buttons are small so if you got BIG fingers you may struggle. But I can't imagine the Canon unit is any different. Love it. Changed my life :-)

    Outstanding wireless flash sync for radio controlled flashes like the 600EX-RT. Not only one third the price of the Canon unit, but better (as it includes low light focus assist). Perfect rendition of the Canon flash menu, so if you know your 600EX-RT, you'll know this. I've used it with only two flashes so far, but excellent performance. Only drawback is that it does not quite fit snugly in the hotshoe of my 70D or 6Ds. Close but not quite. Great seller too, very good follow up.

    Tested my new YN-E3-RT transmitter with a 5D MKIII and a 6D and three original Canon 600EX-RT flash units. It came with 1) a fitted nylon pouch (no belt clip) 2) English + Chinese(?) manual (PDF copy on manufacturer site for download too) 3) two coiled remote cables (remote release from a slave flash unit) with a male mini USB on the one end (goes into the YN-E3-RT) and a Canon specific male on the other (two different ones for 1. the 60D and T3i etc cameras and 2. for the 6D, 7D, 5D etc cameras). You will need / not coming with it: 1) Two AA batteries 2) USB cable (computer to mini USB) for updates Manual mode, TTL and High Speed Sync work great on all channels. The build quality is pretty good, although the YN-E3-RT unit sits a little bit lose on the camera hotshoe. Nothing to worry about, but just a little bit of a dislike here (it 'wobbles' a bit around when dialing the wheel but does not lose the connection). The display and menu is a stunningly exact copy of the Canon menu. The color, fonts, icons and buttons cannot be told apart from the Canon product. The YN-E3-RT is a total replica of the ST-E3-RT unit. If you would scratch off the Yongnuo brand logo I wouldn't notice that I'm not handling a Canon product. +++ Problems +++ Okay, this thing didn't work out of the box for me: The YN-E3-RT was firing my 600EX-RTs but they were out of sync. Weirdly they worked in Hyper Speed Sync mode (shutter speeds 1/250 and shorter) but on any longer shutter speed the flash fired too early or too late. Resolution: Firmware update (after the update to version 1.07 everything worked great together). This was a bit of a pain for me so let me guide you through the process. 1. Check for software of unit: "Menu 4" > "Ver." 2. Go to their website HKYONGNUO dot com > Flash Equipment > YN-E3-RT 3. Download "driver & software" and the latest firmware (two different zip files) 4. Unpack the zip-files and install the driver (in the "Driver" folder), Windows otherwise won't recognize the product as of now 5. Start the trigger updater software 6. Connect the YN-E3-RT with a USB cable (not provided) to your PC 7. Hold the "MODE" button and turn the YN-E3-RT on, display will say firmware update 8. Follow instructions in the trigger updater software I'm pretty happy with the transmitter for now given the high price difference between the Canon original and this one. Will update this review in the future when I have more field-experience to share (product was just released a few weeks ago). ++++ UPDATE 4/2014 ++++ Product works great, tested on several photo shoots and 2 weddings. Nothing to complain. ++++ UPDATE 10/2014 - compared to ST-E3-RT ++++ I got myself a Canon ST-E3-RT and after using the genuine Canon product I lowered the star rating to the Yongnuo down to 4 stars, still taking the low price into account. The most obvious difference between the Yongnuo and the Canon is the built quality, the Canon sits on the hotshoe like a rock. Also what annoyed me a little bit with the Yongnuo was the fact that it often "jumped" out of the menu when scrolling the wheel to adjust flash power. Definitely not a deal breaker but the Canon does not do that. The Canon does turn on significantly faster and the connection to my 600EX-RT flashes is established within less than a second, while the whole process takes about six or so seconds with the Yongnuo. The more important difference between the two is when it comes to reliability. While I found that the Yongnuo works excellent with one flash or maybe two, it really falls short in a setup with 3-4 600EX-RT flashes. Often one of them would not fire or only when used in close distance to the Yongnuo. When using the Yongnuo with just one flash (probably the most common setup) the reliability is pretty good, not remarkable though. It means that in 95% of cases it will fire the flash but then once in a while it will need to be turned off and on again. As for the working distance, I did not do any side by side comparison but would go out on a limb saying that the Yongnuo is not as good as the Canon here. With the YN-E3-RT I had problems firing through walls on distances of 30 feet and more. Nothing of the above is a absolute reason to pay twice as much for the Canon, but then if you have a couple of 600EX-RTs you have paid so much for them that the $150 price difference is not worth any possible headaches. At this moment Yongnuo has announced but not released their copy of the 600EX-RT flash. Maybe the YN-E3-RT will work better with those.
