Flash Trigger
Yongnuo has made various triggers over the years with various protocols, with each protocol improving the functionality of the last. It has made its product line segregated, causing it to lose out on the competition against Godox's Wireless X system. Yongnuo's wireless ecosystem comprises 4 protocols, namely the 602, 603, 622 and E3 protocols. Early triggers such as the 600, 601, 602 and 603 transmit the fire signal only, while later triggers used the improved 603 protocol, essentially known as the 560 mode, to implement the ability to transmit Flash mode, TTL, HSS, Group, ID and Power data. The 622 protocol was created as a stopgap to implement the transmission of TTL, HSS, Group and Power data, but was not backwards compatible the 603 protocol and thus making the product line segregated. The 622 protocol ultimately failed to gain traction, as most of the flashes integrates the 603 protocol, including the YN200. Yongnuo realized that to compete with Godox's Wireless X system, it needed to enhance the 603 protocol. This led to the creation of a unified ecosystem with the introduction of the YN560-TX Pro, which uses the improved 603 protocol (560 mode). The E3 protocol is used exclusively to integrate with Canon's proprietary wireless radio protocol only.
The flash triggers produced by Yongnuo are famous for being compatible with Canon, Nikon, Sony, etc. RF603 recognized by photographers, RF603 II has become the benchmark for flash triggers.
