Yongnuo RF-603C II Reviews

Simple to use and works well

By Dan

Date: 2021-06-08

I've used these triggers for a while now (including the previous model, which had a stupidly-placed on/off switch - the new ones are much better), and they've been great. While not offering ETTL metering or the ability to dial in the flash intensity, it's rarely been a problem, as I typically run the speedlights in manual mode and adjust the output manually. I have two pairs of these, for a total of four units, and this works perfectly for team photos as I have one on the camera, one for each of my two speedlights, and one in my hand as a remote shutter button. Hard to go wrong with these, until you're ready to move up to ETTL remote triggers.

Simple, Cheap, Foolproof

By Matthew
Rated 5 out of 5

A simple, cheap, and foolproof way for anyone wanting to enter the (often intimidating) world of off-camera lighting without having to strap a GameBoy-sized gizmo to their hot shoe. I've had these now for over 2 years, shooting once or twice a week, and I've yet to replace the batteries or have a strobe fail to fire. For anyone curious if these will work with SONY bodies, the answer is yes and no. YES they will fire an external flash; NO they will not work as a remote trigger (no 3-pin connector on the SONY).

Low cost, great performance

After years of only shooting with a flash mounted on the camera - and often being frustrated by the technical and creative limitations of not having the option to move it off camera - I finally decided I needed a wireless option and found these Yongnuo flash triggers were available, for a very good price. Super easy to use, just flick the (tiny) switches in the battery compartment to the same channel and they're ready to go. After four months of use, they have not let me down once. The flash fires every time and I doubt most people would ever reach the limits of the range in normal shooting - works great even from several rooms away. And plugging in the included cable turns it into a remote shutter release which is quite handy. It's great to have the camera on a tripod and have the flash in your hand and move it around freely while taking shots to quickly get lots of different lighting looks. The shutter release feature can also be used with no flashes involved. All in all, an essential accessory if you have a flash unit and are wanting to get it off the camera body without spending tons of cash. I have not encountered any problems with it yet and will probably be buying another pair in the future so multiple flashes can be added to the mix.

Stopped working in the middle of a shoot

By Robert

Date: 2020-06-07

Ordered in April 2020, died in the middle of a shoot June 2020, the first time I tried to use them for a shoot after doing some perfunctory testing beforehand. Was using them as a remote shutter release when one of the radios lost contact for no apparent reason. Replaced the batteries, changed channels, etc., nada. Fortunately I always carry an alternative but disappointed because I can no longer return them. I'll get over it as they are cheap, in every sense of the word, but I would warn people not to rely on these.

Great connection for camera to flash

Simple, reliable, versatile and they use AAA batteries. Each trigger can be used as a transmitter or a receiver. Easy switch for on/off, transmit or receive and a four pin switch in the battery compartment to select frequency. Incredibly reliable as I use four triggers for capturing images of hummingbirds.

Little workhorses

I have 5 of these little guys and I love how small and simple they are to use. Only one has died in about 6 years. I use them as both flash triggers and shuttter releases. Very simple to change the channels and switch between transmitter and transceiver mode. I also love that they work seamlessly with Yongnuo flashes without needing another trigger mounted to the flash. I love these things

question

Can these sync faster than 1/320 when using a leaf shutter?
Asked by: Anonymous
Unfortunately, no, it cannot. Due to the slight delay when using a radio wireless trigger for wireless flash usage needs, the maximum flash sync speed avaialble when using the radio remote system is often lower than the camera's maximum flash sync speed. With many cameras, the maximum sync speed when using the Yongnuo RF-603C II would be 1/250 sec, but the maximum flash sync speed possible would be 1/320 sec, regardless of the type of shutter used by your camera.

question

Will this work on a Leica M10 to trigger a YN560 set in manual mode?
Asked by: Anonymous
Technically this should work with the Leica M10 and a manual flash. The radio sync has a standard hot-shoe so it will fit the flash and the camera’s shoe. Note, it has not been tested specific with that camera and flash combined.

question

Will these triggers work with a Canon EOS Rebel t5 and a Nikon SB-28? And will they wake the SB-28 from sleep mode?
Asked by: Sam E.
This trigger will work on a Canon T5 to fire a Nikon flash off camera but in manual mode only. In order to keep the flash awake, that is a setting in the flash itself. The trigger will not keep it awake.
