Yongnuo flash triggers

Yongnuo flash triggers are the best way to achieve off-camera lighting. In most cases, you will need 2 flash triggers to remotely trigger 1 flash (1 trigger has to be mounted on camera hot-shoe – transmitter, 2nd trigger has to be mounted on flash speedlite – receiver). if you want to trigger 2 flashes, you will need 3 triggers etc. The exceptions are flashes with built in wireless receiver like Yongnuo YN600EX-RT with built in Canon RT system, Yongnuo YN685 with integrated Yongnuo YN622C or Yongnuo YN560 IV or Yongnuo YN660 with integrated Yongnuo RF-603 receiver.
Yongnuo offer two categories of flash triggers: TTL flash triggers like Yongnuo YN622C II for Canon and YN622N II for Nikon and Manual flash triggers like Yongnuo RF-603C and RF-605C for Canon and Yongnuo RF-603N and RF-605N for Nikon
