Product Reviews

I love them!

These are amazing. I have been using them for around 4 years for professional portrait and real estate photography. They hold up extremely well, I have dropped them many times on hard ground and even in water and they still work. The range is strong and they are small and simple. I actually prefer these over more expensive triggers such as pocket wizards for 2 reasons.1: They are small and mount to your camera and flashes easy. Where as things like pocket wizards are bigger and often hang off of your strobes.2: These are super cheap! And I don’t have to worry about losing them, breaking them or having them stolen.3: Okay had to add a third one. I used these on a shoot along side pocket wizards and they actually preformed better. My photographer friend was amazed because he is always trying to get me to buy more expensive gear, but he liked these better than his pocket wizards.I just bought some more recently sense I bought more strobes. :)

The solution that I was looking for in my real estate photography….

I have used a number of different trigger setups with my a6000 as I work through my real estate photography business. I don’t like the built-in WIFI app because the range is limited when you need to set the camera up outside and trigger from inside the house with your flash to brighten the windows one-by-one. I also don’t like the length of time the WIFI app takes to recycle and get ready for the next shot. I also don’t like the fact that the app doesn’t have the ability to shoot brackets. So I had to seek a new solution.Next I upgraded to the Godox/Flashpoint lithium-ion speedlights and got the fat boy R2 flash trigger. If I didn’t want to touch the camera though, I had to trigger the actual camera with a $10 infrared remote. The problem with that is that the receiver on the a6000 is right under the main shutter release button. So if you set the camera up in one part of the room and the angle between you and the camera is such that the lens is between you and that receiver window….you can’t trigger the camera! This happens half the time. Every time you’re standing to the left of the camera.That brings me to these RF-603c-ii flash triggers. I was able to mount one of these to the hot shoe of the camera and then connect it to the camera to use as a shutter release with the Pixel CL-S2 cable. With both of these triggers set to “TRX” I can use the second one from anywhere in the room to trigger the camera. And since it’s traditional radio triggering, it reaches further.What about triggering my Godox flashes? Well I got the Godox XT32C flash trigger. I attach it to the Yongnuo trigger that I keep in my pocket to trigger the camera in the hot shoe and use a Male-to-Male Flash Sync cable to connect the two. While this may seem complicated the result is I have remote control in my pocket that can wirelessly control the flash power of my speedlight groups and when the button on the Yongnuo trigger is pushed…..the camera fires and the flashes trigger and we’re good. Love it.

Work perfectly. Very flexible.

I bought these to replace the long sync cable I was using to trigger my vintage studio strobes. At this point I’m using the Yongnuo units just for that purpose, and these transceivers worked perfectly out of the box. The fact I can also use them to remotely control my camera from 100 meters away is a bonus. (Canon owners: One of Yongnuo remote-control cables has an “N3” designation. It has NOTHING to do with Canon’s proprietary N3 remote-control port. In Yongnuo’s naming convention, “C” signifies Canon, and “N” signifies Nikon.) Manual was very poorly translated from Chinese, but these are simple enough to figure out, and there’s plenty out there on the Internet to answer any questions. Also, note that there is an older version of this Yongnuo wireless flash trigger. On this date in September 2016, the current version is designated with the Roman numeral II. Make sure you get the current version.

I was able to get good shots. I don’t know if I’m the reason …

They work now… At first I could not install onto the camera, or into the flash stand nor into each other, I checked all part numbers and do have all correct items for canon units, I had to file both units lock pins with a small file until they would slide into each other then into the camera. After installing batteries and set up the units per instructions I was always getting shots that were way over exposed no matter what I did with the camera settings. Once setting the flash (speedlite 430EX) into manual and turning down the flash output to ¹⁄₆₄ which is my min. I was able to get good shots. I don’t know if I’m the reason yet so I have to test some more before I judge that, I will return with more info once that happens. I still gave 3 stars for now because they are working wirelessly like described and with the camera in manual they seem to work good even with the flash at min, and I try to give a very fair review when I give one.

Awesome, usable transmitters

Pretty nice little transmitters that actually work! You can’t beat these for the price. I use Eneloop and EBL rechargeables in mine and they last a long time. I have on occasion, experienced some misfires. It’s hard to tell if it’s due to the transmitters or the flashes I use. These sync up no prob with my Canons. I’ve had one break due to it falling and breaking the metal piece off. (Connected to a flash and umbrella, wind blew it over) Not the end of the world tho. Inexpensive enough to buy a couple more. You really get some usable transmitters that are low profile and actually work! It’s hard to spend 2x or even waaayyy more on some transmitters out there. If you need a wireless setup, you really should give these a try.
