Yongnuo YN622C II wireless triggers for Canon. This is the mark II version of the world’s most popular radio triggers for multiple flashes photography. Build quality is improved over already well built original YN622C so YN622C II triggers now come with quick release lever locking hotshoes, USB port for firmware updates, as well as an easily selectable 560-RX mode and slightly more flush mounted buttons. YN622C II triggers support e-TTL (II), HSS, manual, multi modes, Flash Exposure Compensation (FEC), Flash Exposure Bracketing (FEB), modeling Flash, E-TTL group ratios and much more… Pair them with YN622C-TX master controller and you will have all the same functions as much more expensive Phottix Odin, Pixel Kings pro or Pocket Wizards.
