Canon radio flash capabilities are trickling down from their flagship model with the integration of a 2.4 GHz wireless triggering system with master and slave capabilities in the mid-range Speedlite 430EX III-RT. Much like its predecessor, the E-TTL / E-TTL II unit has a guide number of 141' at ISO 100 and 105mm along with a zoom range of 24-105mm and a wide panel that extends coverage down to 14mm. Bounce has been expanded with the ability to rotate 150° right and 180° left as well as tilt upwards 90°.

Enhancing operation are a dot-matrix LCD and a Multi Dial for smooth maneuvering of the menu settings. In addition to the newly implemented radio system for wireless flash, optical slave transmission is still available for greater functionality. The 430EX III-RT's electronics have been sped up with a faster recycle time of 0.1 to 3.5 seconds along with a Quick mode that shortens this to just 2.5 seconds.
