    Yongnuo RF-603II C1 reviews

    RF-603C II Wireless Flash Trigger Kit for Canon 2.5mm Connection is rated 4.7 out of 5 by 36.
    Rated 5 out of 5 by from Does as it states First do not compare these to ones that are 10 times as much. These do as they say and do it well. I love that they are receivers and triggers all in one. They work great with Holga Manual Shoe Mount Flash, they will not work with my sigma 500 series flash. That is not a problem I bought a couple of holga flashes and a old canon film camera flash and they work perfect. These are not line of sight, I set them up in the living room and went out to garage and test fired them ,they worked perfectly. They do what they say and do it every time. For the money I think these kick butt. For anybody tight on cash these are well worth the money.

    Rated 5 out of 5 by from Sony A6000 and Yongnuo speedlight yn560 III compatable A bit of history: After doing some research on triggers I came across the Nikon yongnuo ( the RF-603N II ) in numerous videos and articles that said they work. After buying them they did not work, no matter what I did. Defeated, I came across these after watching one video that used the canon ( RF-603C II ). Since these are only $bucks I thought, Yeah, sure, OK ill try these as well. They work. Not one issue. (though I did take all the paint off my hot shoe previously for the Nikon version, you may have to do this --but not sure!) The pins connect without tightening down and are snug, so attachment and release is slick. I hope I save someone $bucks by not buying the Nikon ones for their a6000. Cheers!

    Rated 5 out of 5 by from Fantastic value Small, light, east to use, and such a good price. I almost wish I had ordered 2 more, because I now realize the potential of a multi-flash setup. You can even use them as a remote trigger for your camera. Very versatile product. I was shooting northern lights and used a flash to light up a church in the foreground. With a 30 second exposure, the flash went off a few times (not sure why), so I simply removed the trigger from my hotshoe and just fired it once during the long exposure and it worked fine. That also allowed me to move the flash during the exposure to better light the building. I also made a multiple exposure effect by zooming in a bit, firing the flash off again, and repeating. Neat effect.

    Rated 5 out of 5 by from Work perfectly! I actually got these for a Pentax K3-ii -- the wire is a pretty standard cable release, as opposed to the weird proprietary ones used on some Canon cameras.� I'm using these for remotely triggering the camera for light painting, and they work great.� So much better than Pentax's official remote, which is IR instead of RF. These allow remote shutter release with precise timing, from any angle. Half-press for auto-focus works great too.� Closest thing to a drawback is that the TX/TRX switches don't work quite like I would expect them to. The only way I could get it to trigger the shutter was if BOTH units were in TRX mode. I would have expected to have the transmitter in TX (transmit only) mode. But once I figured that out, everything is awesome.

    Rated 5 out of 5 by from Love These, Great triggers if you don't need TTL I got this set of triggers to go with my Yongnuo Yn560-IV Speedlite and my Sony A6300 camera (Both from B&H). The work great and are quite versatile in what I can use them for. Firsts they work with the flash so I can use one of the to remote trigger the flash. In other reviews I have seen these go a longer distance than I would ever need. This alone makes them wort the price. If needed I could trigger another brand of flash as well. I also purchased a Vello 2.5mm to Multi-terminal cable (B&H # VERCCS225 ) and by plugging in the 2.5mm end to the trigger I can use the other remote as a remote focus/shutter release for my A6300 camera and/or fire flash. I have even used it as a wired shutter release cable by holding the trigger in my hand while it was plugged into the camera using the cable. Love these.

    Rated 5 out of 5 by from just great. Got these to work with my Fuji xe1 and they work perfect. Also work great on my 5d. Using them with my yn560 iv's best deal ever.

    Rated 4 out of 5 by from good wireless distance best used for distance wireless remote camera trigger, with a good accuracy of 100% out of sight remote trigger
    Date published: 2015-03-22
    Rated 5 out of 5 by from Great Flash Trigger set This is a great flash trigger set, especially for the cost. I was able to walk around a large room without it misfiring. If you're looking for a simple trigger/receiver set, then look no further. I also really like that they can be used as a wireless shutter release. This is my first Yongnuo product, but I've heard great things about them. I will definitely consider them for other products I buy.
