Compatible with Canon E-TTL / E-TTL II, the YN686EX-RT is able to benefit from direct communication with the camera for automatic exposure. Also, it is equipped with a Canon-compatible 2.4GHz radio system, allowing it to be easily integrated into existing systems as either a master or slave. Furthermore, the flash offers optical transmission as a master for Canon flashes or as a slave for either Canon or Nikon systems.
Powered by a rechargeable lithium battery pack, the YN686EX-RT benefits from fast recycle times of just 1.5 seconds at full power and the ability to get over 600 flashes on a single charge.
The flash features a powerful guide number of 197^27 at ISO 100 and 200mm as well as a zoom range of 20-200mm with a pull-out diffuser available for 14mm coverage.
