Yongnuo YN685 vs YN660 vs YN600EX-RT

All three flash units use different RF systems.

The YN-600EX RT and YN-E3-RT are compatible with the Canon 600EX RT and ST-E3-RT.


The YN-685 has a built in YN-622 receiver. It can be used with a YN-622C on Canon cameras or with the appropriate YN-622-TX on either Canon or Nikon cameras.


The only reference to the YN-660 I can find is this one. It appears that this flash is an upgraded YN-560 IV that can use 6 groups instead of 3 and the GN has increased from 58 to 66.
