Love the YN-E3-RT for what it is, but with a few caveats.

Reviewed in the United States on December 3, 2016

Verified Purchase

I've had mine since May '15 so I've put mine through the ringer a bit. I bought mine mainly because of the price and the AF assist beam compared to the Canon ST-E3. Was seriously considering the Canon version when I dumped my 580EXII for 600EX-RT but I don't regret not buying the Canon version a bit. It works perfectly with my 1Dx/5DIIIs controlling 3x 600EX-RT. The AF beam proved to be clutch, even with its somewhat off-center, funky-looking pattern.

Now, for the negatives: The AF assist beam doesn't seem to work with I mount the unit to my 1Dx MkII. Everything else works but that's just unfortunate. Really hope Yongnuo can update the firmware to address this bug. Also found out the YN-E3-RT will trick the 1Dx mkII into limiting the shutter to its flash sync at 1/250 even if the transmitter is turned off. Which means you'll have to remove the unit (instead of just turning it off) from the camera if you want to shoot at a higher shutter. It's no big deal if you're just shooting around, but it's an annoying extra step while shooting a event. Was going to order a second one but I am going to wait until it'll work properly with the 1Dx Mark II.

... had this for about a month now and I love it compared to what I use to use

Reviewed in the United States on January 27, 2015

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.

Requires firmware to work with 430ex iii-rt

Reviewed in the United States on April 18, 2016

Verified Purchase

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.

A nice product for a great price (also works with 430 EX III RT)

Reviewed in the United States on February 27, 2016

Verified Purchase

I bought this to control both my Canon 600 EX RT's as well as my Canon 430 EX III RT's. I contacted Yongnuo and they told me it will work w/ 430 RT as long as I got the latest firmware. I updated the firmware and matched the 4 digit ID but it wasn't until I changed the channel to "auto" that everything worked fine. Now all the flashes and this affordable accessory talks just fine.

Some other things to note. The AF assist cluster is not well thought out but it's nice to have. The cluster is noticeably off center towards the top of the camera and doesn't cover all the focus points. Still, it's nice to have but I think it could have been designed better.

The battery door is a bit stiff and the unit sits on my 5D Mk III with a little play but overall, the build quality is not bad at all.

Won't work with Fuji X-T1, but works flawlessly with a Canon.

Reviewed in the United States on June 2, 2015

Verified Purchase

I was really hoping this would work with my Fuji X-T1 to trigger my Canon 600ex-RT flashes. Well it triggers them, but the shutter goes off first and then the signal gets to the flash or flashes. If you have two remote, it will fire the first one and then the second one, both delayed from when the shutter activated. Bummed. You would think it would fire at the same time, but must be something to do with the Fuji hotshoe.

When paired with the Canon Camera (5DMKIII), it works flawlessly. Sync's right up to the flashes. Works just as good as the Canon version, plus it has infrared so you can have a red beam of light go out to focus in dark situations. It feels and look just like the Canon, but the buttons are cheaper and there is a less positive feel to the way the buttons and dials work. Hey, it was only $100 so can't complain. Not sure if I'm going to return it. It may come in handy during a reception at a wedding or to give to my second shooter at weddings so we can use the same flashes.

Working flawlessly for me!

Reviewed in the United States on March 6, 2017

The only thing to be aware of, in my opinion, is that currently the AF assist beam does not work with the 5D Mark IV. I've used it to trigger the Yongnuo YN600EX-RTII flash, Canon 600EXII-RT on the 5D Mark IV and the 5Ds.
The inclusion of the AF assist beam on the Yongnuo transmitter is GREAT as the Canon transmitter does NOT have it (which is ridiculous, IMO). The range of the Yongnuo transmitter is 100 meters whereas the range of the Canon transmitter (ST-E3-RT) is only 100 feet. So the Yongnuo transmitter will work more than 3x the distance vs the Canon.

YN-E3-RT - Funkgesteuerte Blitzsteuerung zum günstigen Preis

Reviewed in Germany on June 8, 2018

Verified Purchase

Der Yonguno Transmitter YN-E3-RT ist Insgesamt ein sehr gut gelungene Kopie des Originals von Canon. Im Normalbetrieb absolut ok – ich würde ihn auf jeden Fall weiter empfehlen. Eindruck der Qualität: Nicht ganz so wertig wie Canon, aber trotzdem gut.
Aber 2 Schwächen sind dennoch vorhanden, welche hoffentlich in naher Zukunft durch ein Firmware-Update behoben werden. Deshalb vergebe ich nur 4 Sterne. Nachfolgend sind die von mir momentan vorhandenen Schwächen des Transmitters aufgeführt. Nur die erste halte ich für gravierend, ist aber umgehbar.

Für die Tests verwendete Ausrüstung:
Canon 5DMIII/2x Canon 600EX RT/Yonguno YN-E3-RT (aktuelle Firmware 2.15)
Aufteilung der 600EX RT: 1 Blitz in Gruppe A / 1 Blitz in Gruppe B.
Alle anderen Gruppen sind ausgeschaltet / Einstellung beider Gruppen auf ETTL

Fehler Belichtungskorrektur - folgende Situation:
Wird am YN-E3-RT eine Belichtungskorrektur eingestellt z.B. -1 für die Blitze in der Gruppe A und alle Blitze der Gruppe B wird das am Blitz selbst (nach erfolgter Auslösung) nicht angezeigt. Die Aufnahmen werden jedoch korrekt um 1 Blendenstufe weniger belichtet.
Ist allerdings an den Blitzen selbst eine Belichtungskorrektur eingestellt, scheint es so zu sein, dass sich die eingestellten Werte am Blitz und am YN-E3-RT addieren. Eine Einstellung am Blitz auf +3 und eine Einstellung am YN3-E3-RT auf -3 liefert normal belichtete Bilder.
Erfolgt die Belichtungskorrektur am Blitz auf +3 und am YN-E3-RT auf +3 erhält man total überbelichtete Bilder (3+3=6= Blendenwerte).
Also darauf achten, dass an den verwendeten Blitzen keine Belichtungskorrektur eingestellt ist.

Fehler bei Multi-Blitz Funktion:
Zwar wird die am Transmitter angezeigte Frequenz (Hz) an den verbundenen Blitzen angezeigt, aber nicht die gewählte Anzahl der Blitze. Die Funktion ist nur im manuellen Modus der Kamera verwendbar, im Bulb-Modus (B) werden die Einstellungen ignoriert (funktioniert wenn der Blitz direkt auf der Kamera montiert wird). Man kann also nicht nach der Aussendung des letzten Blitzes über die Einstellung B sofort die Belichtung beenden.

Bei allen anderen getesteten Funktionen verhält sich der Transmitter wie erwartet. Entfesseltes Blitzen gewinnt eine ganz neue Dimension!
Nicht getestete Funktion: Linked Shooting

YN E3-RT ottimo con 5D MKIII + Speedlite 600EX-RT + Yongnuo 600EX-RT

Reviewed in Italy on July 18, 2017

Arriva in una bella scatola come da foto, in cui tutto il contenuto è ben compatto, senza compromettere danneggiamenti.

Il trigger vero e proprio è contenuto in un astuccio da trasporto identico all'originale Canon (ma senza brand, naturalmente) con all'interno una piccola quanto utile bustina di silice anti-umidità.
Nella scatola oltre al trigger con custodia da trasporto si trova: cavo di aggiornamento firmware e cavo sincro-flash, libretto istruzioni inglese/cinese, certificato di garanzia in cinese.
Risolvendo il problema del libretto inglese/cinese semplicemente scaricando quello originale dal sito Canon, ci si semplificherà parecchio la vita, in quanto le istruzioni originali sono decisamente più esaustive.

Per quanto riguarda la qualità costruttiva posso dire che mi sembra più che adeguato per svolgere la funzione a cui è destinato; l'attacco a slitta ha lo stesso concetto della nuova serie di Speedlite (guarnizione in gomma e serraggio con pulsante); il vano batterie va richiuso con delicatezza per evitare di forzare la leva metallica incastonata nella plastica; pulsanti e ghiera hanno la stessa "risposta" dello Speedlite 600EX-RT (la ghiera è forse leggermente più morbida, nel senso degli scatti in rotazione).
Una volta acquistato l'ho dovuto aggiornare con il firmware del 2017, preventivamente scaricato dal sito Yongnuo; facile ed immediato.

Il display ha la stessa qualità dell'originale Canon e le funzioni direi che sono molto simili (a giudicare dal confronto con il libretto di istruzioni originale); forse nel menù personalizzato si poteva aggiungere qualche piccola funzione come la colorazione del display o il maggior contrasto dei cristalli liquidi, ma si tratta di un semplice parere personale.

Ho notato che equipaggiando la mia EOS 5D MKIII con Speedlite 600EX-RT e YN 600EX-RT, premendo il tasto di prova DoF (profondità di campo), questa si attiva sullo Speedlite ma non su YN; credo sia dovuto ad un limite del flash YN, piuttosto che ad un limite del YN E3-RT.

Usato in combo con almeno 2 flash, permette di dare ai propri scatti la creatività che il semplice flash montato on-camera non può dare!
Funziona anche con i modelli EX di Canon (580EX I e II, 600EX, e via dicendo).

Spero che la mia recensione ti sia stata utile. Se per te lo è stata, ti prego di manifestarlo col pulsante qui sotto.

I am impressed. Had my doubts but I am glad I bought this.

Let me start with the delivery. Ordered 31st August-2016.
Initially the forecast delivery date was Wednesday 7 September. Lo and behold, the item was delivered on Sunday (yes, that's right, Sunday) 4th September.

I took my time in testing it. But I checked the box contents immediately I received it just to ensure all items were included.

On Monday I proceeded to setup and test (when family had gone about their daily tasks so I had enough time and space).

First thing I did was to ensure firmware was up to date. I realised that the coiled cable included in the box actually had micro USB at both ends: one to plug into the Yongnuo YN-E3-RT, the other end to plug into the USB port of the computer. Hmm. Scratched my head. Fortunately I remembered that the Canon 5D Mark III had a micro-to-proper-USB end so I used it instead.

Connected successfully and updated the device with no problems. You have to look around on google for a link to the landing page for firmware because Yongnuo home page is all in Japanese.

Anyway, ready to configure and test.

Yongnuo YN-E3-RT (+2 batteries)
Canon 5D Mark III
Canon Speedlite 600EX III-RT (+4 batteries)
Canon Speedlite 430EX III-RT (+4 batteries)

Config setup was easy. Why? Loads of YouTube clips showing step by step
One of these: https://youtu.be/e14UhoCOloA

Testing was successful and I'm happy with this purchase.

If I need more Speedlite strobes / flash I will definitely consider buying a Yongnuo one (reasonably cheaper than top branded version).
