Introduction

Introduced March 2015.

The Yongnuo YN-E3-RT is a compact radio transmitter which sits on the camera’s hotshoe and can control speedlites such as the Yongnuo YN600EX-RT II or the Yongnuo YN968EX-RT. The YN-E3-RT uses the Canon RT radio system and is therefore compatible with the newer range of Canon’s radio-enabled speedlites such as the Canon 600EX II-RT, 600EX-RT and the 430EX iii-RT.

Using a dedicated radio transmitter on your camera has the advantage of being much smaller and lighter than using a master speedlite to control slave flashes and it’s also cheaper. The YN-E3-RT has a range of up to 100m, supports E-TTL II and high speed sync. It can control up to 5 groups and up to 15 speedlites and has an infra-red autofocus assist lamp.

As many people will realise, the Yongnuo YN-E3-RT is almost an exact copy of the Canon ST-E3-RT transmitter.
