Hi, I use three RF-603c II's with my 6d. I use one on the camera as a trigger, and two as receivers on two flashes (Yongnuo YN568EX [which also has five contacts] and a Neewer TT560). They only work on the TRx mode, but they've been working perfectly so far. You've checked that the channels on the trigger/remotes are s… see more Hi, I use three RF-603c II's with my 6d.

They only work on the TRx mode, but they've been working perfectly so far. You've checked that the channels on the trigger/remotes are set to the same combination? I can't think of anything else that could be a problem. Like I said they work perfectly with my 6d. So much so that I'm about to order two more RF-603C II's to go with another flash that I just got. Hope you get it sorted out. Best of luck. see less

Yes it will. I've used them with my 6D numerous times.

Yes, it does come with a sync cord for Canon EOS cameras. In this case I also have a 7d and it works perfectly.

All Canon flash mounts are identical.

--yes, C1 cable will help you use RF603 trigger as a wired and wireless shutter releaser. if use as flash trigger,
By Mckenna on May 8, 2018
They will work as long as you have the right cord for the camera
By Mr imperfection on May 10, 2018
It doesn't have HHS or any high sync speed but it will work on canon Dslr also you can't control your flash with the camera manue only on the flash

603 can help 5DIII trigger the YN560II. but flash mode have to do setting on the flash light itself.

These flash triggers do exactly what they are supposed to do and more. Since they work also as a shutter release you can fire the flash with the transceiver that it is attached to while also activating the shutter with out ever touching the camera. This means I can hold a speedlite in my hand with a RF-603 attached to it and fire the speedlite with the test button on the transceiver and it will fire the flash and activate the shutter on the camera. this make doing composites a lot easier. this little bit of information wasn't in the description but i did find it buried in the manual.

My RF-602 triggers are aging and that CR2 battery is a real PITA, so I thought I'd try picking up a set of the RF-603II triggers not only for the numerous improvements (locking ring, on/mode switch on the SIDE of the unit, the test button working in hand, etc.) but because these would be compatible without modification with my micro four-thirds camera (Panasonic G3). Worked great out of the box on both my Canon and Panasonic cameras. But. Whether I got a bad unit or a bad cable, I don't know, but the set could not be used as a shutter release with my 50D and 5DMkII, so I am returning them. In addition, I could not get another feature that was mentioned in the specs to work at all, which was the use of the PC port as a triggering input (from, say, a camera's PC port or a light meter) in Tx mode. I like to use a small optical slave in conjunction with the pop-up flash of my Powershot S90 to do radio off-camera flash triggering sometimes (I'm just weird that way), and it works fine with my RF-602s (which are old enough to still have the PC input port on the Tx unit). Couldn't get it to work. And the manual that came with the triggers describe the PC port as an output only (just like on the Mk I 603s). So if this was the feature you wanted the triggers for, you may want to wait and see if anybody reports success on this. Other than that, the triggers were great are popping off remote flashes in my testing, and I'm sorry the other features didn't work as I expected them to.

I'm using these to trigger multiple Yongnuo YN560 IV speedlight strobes with built-in receivers and they work flawlessly. Since the speedlights have the receivers built in, you only need one of these mounted in the camera hot shoe. If using a speedlight without a compatible receiver built in, you can use the second RF-603 II to fire it. I just keep the second one as a spare trigger. I also have the Yongnuo YN560-TX flash commander which triggers the same strobes, but also allows you to adjust the flash output and other flash settings. The YN560-TX also sits in the camera hot shoe but is considerably larger. However, it will still make all the flash adjustments even if it's not mounted on your camera. So I find it useful to make the adjustments using the YN560-TX commander which I can keep in my pocket and put the RF-603 II on the camera and stay streamlined.

Just received my new RF 603C and was very excited to try off camera flash for the first time. I initially had some problems, but after receiving some advice from a pro photographer I discovered that the problem was not with the RF603C at all, that it was that my flash was not recycling as fast as I was pressing the stutter. I have put new batteries in everything and am not shooting so fast and am not having any issues. I am enjoying these RF603C and will probably purchase another set so I can have 3 flashes set up simultaneously. :) It would be nice in future iterations of this unit if Yongnuo would place the on/off switch in a different location so that it might be accessible while on flash and if some type of simple locking mechanism could be incorporated into the design. That being said, I really like these units.

They arrived packed very securely in 2 per box in 1 package. I was immediately impressed with the packing and thickness of the boxes. I opened them, installed the 2 AAA batteries in each (they do not come with any so have some ready) got my Canon 580EX II out and started taking pictures right away. There is a small instruction manual with each kit, but unless you just want to know the names of the parts, setting the RF-603 up is a breeze. After shooting several pictures around the house, I attached the cable to make it work as a wireless trigger for my camera--worked like a charm. Several have commented that there is no locking mechanism for attaching it to the hot shoe on the camera--while that it true, I found that all 4 of the RF-603 transceivers I received fit snugly on the camera. I intentionally shook the camera to try to get it to slide back and it stayed firmly in place. I have absolutely no complaints about the transceivers. They work as described and saved me a whole lot of cash.

The price/function combo of these triggers is fantastic. I have used them as flash triggers on up to 3 flashes at once with no problems. I recently used 3 of them in a homemade photo booth at my daughter's graduation party. One on a flash, one on the camera with the included cable plugged into the camera to enable shutter function and one in the hands of someone in the picture to trigger the shutter. It does not need line of sight, so the trigger could easily be hidden. It was a big hit. Great product.

If you are looking for a budget flash trigger, look no further. For the price, these just can't be beat. Some of the things I really like about these: Small, takes AAA batteries Work at great distances, a 100m actually seems accurate Triggers each time (tested for two days, about 1000 shots and fired every time) Each trigger can be used as a transmitter or transceiver (transmit and receive), great for when you want to use a light meter On and Off switch on the side (actually switch between OFF, TX, TRX) 1/320 sync speed, I could only test with my Canon 7D at 1/250th Comes with cable for triggering camera remotely, make sure to get correct model for you camera (C1, C3, N1, etc...) Has a Nut so it can be tightened to camera and/or flash Works with Yongnuo 560III So far I have not found anything I don't like about these. Make sure to get Yongnuo RF603 II, the originals RF603 do not have the same options. Ok, so I've had these for several months now, they are still working great, I've even ordered a few more, have about 8 now. The distance that these triggers work is amazing, inside and outdoors.

I am very happy with these flash triggers. I have had no problem with the trigger setting off the flash when I am not taking a picture, a problem I had with a different brand. Occasionally the flash will not trigger but I think that is to be expected. They have a solid build and are low profile. My only complaint and why I did not give 5 stars is that I can not trigger the flash for meter readings unless the unit is connected to the camera and I have half pressed the shutter button and then push the test fire button. Its a pain to do all that with one hand while I hold the meter in front of someones face with the other. I would buy these again.

I was excited to see Yongnuo introduce a new model - I love their flashes, the CTR-301P transmitters and the RF-602 transmitters. The RF-603 is their newest generation of wireless flash transmitters -- they look similar to the RF-602 receivers, but go for a new route. Rather than a Transmitter and Receiver, these are "Transceivers" - meaning they do BOTH. If you buy 4 of them, you can put 3 on different cameras (as transmitters) and 1 on a flash (as a receiver), or put 1 on a camera (transmitter) and 3 on flashes (receivers), or any combination. With the RF-602's I bought 3 receivers and 3 transmitters (for the times I use multiple cameras), this would have allowed me to purchase fewer. Similar idea to the PocketWizards. The RF-603's (like the 602's) can also act as a wireless camera shutter release -- plug the release cable (one is included -- make sure you get the right one for your camera) into a receiver and connect it to a camera, and use the other transceiver to trigger it (by pressing the button on it --

Great product, very reliable when you know how to use it, giggles. I will not detail technical specs and tests I have made, but one thing is for use, if you want these remotes to fire as much as you want them to, please use high quality alkaline batteries and have spares! I have been using the remotes for less than two months and in a testing session they would not fire more than 3 times in a row. My Canon camera got the horrid 99error and I thought it was dead or some major problem was going on. Took me time to realize the Young Nuo 603 needed batteries replacements since the greet light from the units were always green. So I found out about alkaline batteries. Follow my advice it will save you time and brain cells. I have bought this pair of receivers twice, so I have 4 units and they have been working great indoors and outdoors.

I was a little skeptic in buying this product but once I did I was really surprised with how easy it is to use and how well it work. The first time using this product I was shooting an engagement shoot and the only issue I found was that there was another photographer at the venue. it seemed that he had either the same transmitter or was transmitting on the same frequency as I because I was noticing that my 430X II was being triggered when I was not taking pictures. I was able to work around it. This may be a problem depending the situation but it was something I saw this may be an issue for some people. My photo session was outdoors and the flash was being used as a fill light.

Picked these up with the Yongnuo YN 560 III flash and am pleased with the flash trigger function when I have the flash off-camera (the 560 has internal receiver so only one camera-mounted RF-603 is needed here). The wireless shutter release was a function I wasn't planning to use but have used quite a bit to sharpen landscape shots by getting my finger off the camera's push button. The wireless shutter release function also worked great during the holidays to hold one RF-603 while posing to take family photos, eliminating the need to run back and forth to reset the camera's timer function. I'm not a professional photographer and some of my family photos now have me with one of these RF-603 in hand, oops. Overall these units exceeded my expectations.

I almost forgot what I bought this for. This thing has so many uses. I bought it for the wireless remote flash capability but it also works as both a wired or wireless remote for the camera. The buttons on it are two stage which is easy to feel and they work just like the shutter button on the DSLR, at least they do like on my Canon 50D. The remote flash capability works fine. I am please with the ability to move the flash closer to the subject or use it for back fill. Like the Yongnuo wired remote flash this set is well made. It doesn't feel cheap or lightweight. There is no slag or rough edges. I am not a professional photographer, just a serious hobbyist, as such I'm very happy to get a this set that lets me experiment with moving the flash around without spending a lot of money.

Excellent wireless flash trigger for the price. Since my interest was in learning/using off-camera flash, whether hand-held for more interesting light effects or remote placement to under-light or back-light a shot, I just needed a simple trigger. Any flash power adjustments I make manually before the shot. I'd have given five stars but the instructions were somewhat unclear and minimalistic. I spent quite awhile thinking the triggers didn't work and searching the web for solutions. The lights on them showed connection and the flash "should" have gone off...

These are great. I was stuck with a flash and a camera that could not operate in "master" mode and considering buying an expensive master flash. I knew these type of things existed, but most are in the hundreds of dollar range. These are an amazing value, well made, and very reliable. HOWEVER, there is no hot shoe lock. No lever, no screw down, so they very easily wiggle out of the hot shoe and cause the flash not to function. I learned to push the trigger in to the hot shoe on my camera before each shot, but that is a bit tedious. I am not sure why it won't lock; it's fine with a flash on a flash stand, but one has to go on your camera hot shoe and should be able to be secured. Regardless, I would highly recommend these, I'd had many pros tell me they are just as good as the "big names!"

These things are awesome! Work perfectly with my Canon EOS 7D and the Neewer SpeedLight flashes that I use. I attach one on the bottom of both of my flash units, one on the hotshoe of my 7D camera (with the trigger cable attached that comes with the set) and use the fourth wireless trigger to fire my camera remotely for self portrait shots or even just shake free photos. Again these triggers are awesome. Easy to figure out how to use, the instruction booklet is very straight forward, most complicated part is open the battery cover and assigning the same "code" to all the triggers - but even this is very simple, just make sure the number sequence matches on how ever many triggers you intend to use. Simple really.

Everything seems to work quite well. They use normal AAA batteries and use dip switches to change the channel. One LED represents the powered-on state, and the other represents when the flash is "ready" (shutter button down halfway for example). There are two minor problems, both with the physical design. First, EVEN WITH YONGNUO'S OWN FLASHES, the on/off switch is placed such that it cannot be switched once a flash is attached. It's blocked. They could have put the switch ANYWHERE else to allow me to switch the units off without disassembly. Second, there's no way to secure the shoe mount to the camera. It's pretty light and holds in there relatively well on its own, but it's hard to trust it. It slides right out with the slightest tug. This isn't a big deal using the transceivers on off-camera flashes, because off-camera flash mounts have clamps that hold onto the shoe mounts, but it's a minor thing that would have made it seem much sturdier. But other than those two minor physical annoyances, the actual FUNCTION of these units is perfect. I haven't had a single issue, and the "ready" light is great to visually tell that the flashes WILL fire when the shutter is released without actually doing so.

I ordered these along with a YN560 III flash, turns out you only need one of them because the flash has a receiver integrated (which is great) and in theory you can use the extra transceiver as a shutter release remote... and here is the thing, for this feature to work you need a cable connected from the transceiver you place in the hotshoe to the shutter release port in your camera and in this package the cable provided does not fit my SL1 it only fits high end Canon cameras like the 7D... anyway, I'm yet to figure if I get the right cable would if actually work, which I think it will... Other than, and for its intended primary purpose the transceivers work great!

I'll put it simply. These are terrific, never missed a shot triggers. The best part is they are supplied with a shutter release cable for your specific camera. I have ordered 3 sets total so my daughter and I both have 3 each...one on the camera, for both shutter release and flash, second on the flash itself and third one for the hand held remote trigger. However, there is no securing lock or screw...whatever you call it...that secures it to a base on a light stand. It also does not have a screw hole in bottom for a light stand. Great trigger that I think they will redesign to add those problems I've seen reviewed elsewhere. Buy them anyway. Inexpensive and operates flawlessly.

They work perfectly with my setup.Having taken around 100 shots, since receiving these, there were no misfires using the "TRX" setting on the side switch. I have enough confidence in these to have just placed an order for another set. The fact that these are multi-functional "transceivers" that can play either a receive or send function you get a lot of value for the dollar, especially when you consider that a pair of Pocket Wizard X units run $180. For me in buying two sets that's a $300 savings. Although I haven't had the opportunity to test the range, it is listed at 100m and I can't see my use ever getting to that range as I'm usually in a studio or at short range outdoors, using to either complement or overpower natural lighting. Again, for the enthusiast, or even the professional, you really won't believe the quality and performance of these thirty-dollar radio remotes.
