Yongnuo YN-E3-RT Wireless Speedlite Transmitter for Canon

The Yongnuo YN-E3-RT is a wireless speedlite transmitter designed for use with Canon cameras, offering full compatibility with Canon’s RT radio transmission system. It mounts to the camera’s hot shoe and enables wireless control of compatible speedlites operating in master and slave configurations. The unit supports E-TTL/E-TTL II automatic flash metering, high-speed sync (HSS), and second curtain sync, providing a broad range of creative flash control options. Flash groups can be managed independently, allowing for flexible multi-flash setups, and ratio control between groups is supported for precise light balancing. The transmitter features an LCD panel for straightforward navigation of settings and is designed as a transmitter-only unit, meaning it does not emit flash output itself.
