Yongnuo speedlites (flash units) and the Yongnuo transmitter are compatible with each other and also with the Canon radio controlled speedlites and transmitter and can be used interchangeably. Compared to Canon radio controlled units, they are super inexpensive and I love my Yongnuo system pictured above. But there are some warranty issues you should be aware of, so before you purchase a Yongnuo speedlite or transmitter, read my article Radio Controlled Speedlites: Yongnuo YN600EX-RT vs Canon 600EX-RT
Yongnuo Speedlite Wireless Transmitter YN-E3-RT This radio transmitter sits on the camera and controls one or more off camera Yongnuo YN600EX-RT-II speedlites and/or Canon 600EX-RT speedlites.
