In 2012, Canon introduced remote radio control into its flashes with the introduction of the 600EX-RT speedlite. Canon master/slaves flashes in this system now include:
- 600EX-RT II
- 430EX III-RT
And there's a headless transmitter (master) unit, the ST-E3-RT.
3rd-party speedlights and transmitter/receivers that can be used in conjunction with Canon's RT system include:
- Yongnuo YN-600EX-RT (speedlight master/slave)
- Yongnuo YN-E3-RT/RX (transmitter/receiver)
- Phottix Laso TTL transmitter/receiver
The only missing piece in the system seems to be built-in radio transmitters in the camera bodies.
Does Nikon have an equivalent built-in radio triggering system for its flashes? If so, is there any 3rd-party support?
