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 operations are a dot-matrix LCD and a Multi Dial for smooth maneuvering of the menu settings. Also, it offers enhanced Flash Exposure Compensation and Light Distribution settings for making very specific adjustments to the output settings. A color filter and bounce adapter are included as well for adjusting the color temperature and brightness of the flash for more balanced lighting. And, it runs on 4 AA batteries. Light Distribution settings allow for Standard, Guide Number Priority, and Even Coverage settings. Using optical transmission it can be set as a slave with an unlimited number of flashes within 4 channels and 3 groups. Fresh batteries will provide approximately 180 full-power flashes.
