RF-603 II 16-Ch Wireless Flash Trigger for Canon 3-Pin Connection 1D/5D/7D/10D/20D/30D/40D/50D Cameras, 2.4GHz, 1/320sec Sync Speed

simple and it works. These are manual triggers and I debated on purchasing a trigger set that was ETTL enabled for my Canon system but in the end I decided that I end up shooting almost exclusively off camera lighting in manual mode and these would do the trick. I have had zero issues with these triggering each other (when connected between my DSLR and my Canon 580 EXII). They work flawlessly.Also, I then decided that I needed another speedlight and went with the new YONGNUO 560 III for less than $100. This is a manual flash ONLY, but the cool part is that it doesn't need a RF 603II attached to it because it has a receiver for this trigger BUILT IN to the flash head. Now I have one trigger on top of my CANON DSLR, and the other attached to my Canon 580 EX II. The Yongnuo 560 III doesn't need a trigger and I can use a two speedlight setup like this. If I need a third light later on, I will most likely get another 560III to work with these triggers. The YN 560-TX controller works with these 560III flash heads and is good manually control your lighting groups, but seriously, right now my lighting is all within several feet of my reach and I'm not that lazy. The controller in this case would be a good idea if your speedlight is INSIDE of a softbox and you have to open the box to adjust the power, but otherwise with umbrellas and other types of light modifiers that you can access your speedlight easily, these RF 603II triggers are a simple, reliable, and effective way to trigger off camera flash.They arrived exactly as described, in new packaging, in a timely manner. I am very happy with my purchase.

I wasn't sure how good these radio remotes would be, but they work perfectly with my setup using Sony mirrorless cameras (A7, a6000, RX10) using the Yongnuo YN-560 flashes with those set to manual, configuring power and zoom to my liking, usually shot through Wescott umbrellas. Having taken around 100 shots, since receiving these, there were no misfires using the "TRX" setting on the side switch. This is the setting for hotshoe mounting of the flash on the remote. When test firing the "TX" setting is used on the triggering unit and "TRX" on the flash mounted unit.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. I even dropped one on a concrete basement floor with no visible damage and no impairment of function.

BE CAREFUL!!! These are great products when they work, however, while attached to my camera the safety pin became stuck in the down position. I was unable to remove the device from my camera & had to disassemble it to get it off. My camera's hotshoe was damaged in the process. Upon doing some research I learned this issue is not uncommon & many people have faced the same solution. I had to return them & am too afraid to give them another shot.

Let the confusion begin. I placed an order for the Yongnau RF-603 II wireless trigger for a Canon 3-pin (1DX Mk2). The box that arrived stated that it was a Yongnau RF603N II wireless flash trigger and on the side of the box was a red sticker stating for "N" which encompasses the likes of the D3000, D5000 etc. These are Nikon cameras and the "N" on the box obviously means for Nikon. However on the other side of the box along with a barcode was a white sticker that stated this was a Yongnau RF603 II 3 pin for Canon 1D, 5D, 7D etc. cameras. So which is it? Nikon or Canon?Opening the box I found that it indeed was for Nikon cameras and not the 3 pin connector required for Canon cameras. Obviously the wrong type and not as stated on the Amazon page (although I can see the confusion given the two different stickers on the box).What you get in the package is two flash triggers, a short trigger cable and a manual. You will need to purchase 4 AAA batteries separately for the triggers (2 in each).Anyway, after looking at the manual that comes with it I thought I would give it a try anyway as perhaps you don't actually need the trigger cable. I have an older Yongnau YN560-III speedlite which has IR wireless built in so I thought I would try to remote trigger that. After putting in the batteries, attaching the trigger to the camera and turning it on to its TX (transmit) setting, I turned on my speedlite, set it to wireless mode and it worked no problem. I have tried this with a Canon 1DX Mark 2, Canon EOS 70D and also with a Sony A7, all three working as a standard wireless flash.Going through the menu system on the 1DX Mark 2, although there is a menu for external speedlite controls (3rd menu in) it does not however recognize this flash unit so you cannot set the zoom, sync speeds etc. through the camera menu. As such I have to put the flash in manual and just use the triggers as a remote firing mechanism. There is a newer version of the Yongnau, the YN600EX-RT which is TTL and would work with the 1DX Mark 2 (it can also sync to 1/8000 however these triggers only sync to 1/320).Range on the triggers is excellent with it easily remotely firing my flash unit at over 100ft away (manual states that maximum range is just over 330ft).Now as luck would have it, I already had a shutter release cable for my 1DX Mark 2 so I could test everything in one go, remote flash and remote shutter release that having two (or more) of these wireless triggers provides. Attach the flash to one, the camera to the other, insert the sync cable (shutter release cable), set both the triggers to TRX (transmit multi mode) and press the button on the end of the trigger. Worked perfectly. Both the camera and the flash fired.You can buy multiple RF603 triggers and as long as they are on the same channel (a set of dip switches you find in the battery compartment) you can set multiple speedlites to remotely fire at the same time as well as triggering the shutter on your camera. Whilst not as well manufactured or have as many options as other brand remote triggers (Pocket Wizards) such as supporting ETTL you have to look at the price point. Where else can you get a pair of remote triggers for under $30?One thing I will say about these version 2 triggers compared to the version 1 is the placement of the on/tx/trx switch on the side is much better then it was on the version 1. However in saying such, one bad thing about these triggers is that when you put the 3.5mm cable in, you can't push it all the way in till it locks for a connection to happen. If you find your remote shutter function not working, try taking the 3.5mm plug out a little bit and trying again. At first I thought both units were broken until I accidentally ran across this.If you are in the market for cheap but working remote triggers then you can't go wrong with this pair for the price point.
