Radio Transmitter
The Speedlit 430EX III-RT supports not only optical but also radio transmission for off-camera wireless flash shooting. The radio system gives users greater flexibility, thanks to the slave unit's superior freedom of placement, controllability and functional range. (430EX III supports only optical transmission.)

Bounce Shooting Function
The heads of the Speedlite 430EX III and 430EX III-RT are able to turn freely up to 90° up, 150° to the left, and 180° to the right enabling the flash to fire in almost any direction. Referred to as bounce shooting, firing the flash towards ceilings or walls delivers softer and more natural lighting
