Canon Speedlite 430EX III-RT

With the introduction of the Speedlite 600EX-RT, one thing was inevitable – more radio-enabled flashes from Canon should be expected. Surprisingly, the 600EX-RT remained Canon's only radio-enabled flash for more than three years. The (seemingly long overdue) introduction of the Speedlite 430EX III-RT means that Canon's mid-range flash lineup has finally received its much-anticipated refresh. While radio functionality was a reasonable expectation in the 430EX II's replacement, the biggest surprise in the 430EX III-RT's announcement was the flash's ability to act as a radio master flash. Now budget-conscious consumers who do not require the higher power of the 600EX-RT have a lower-cost, smaller and lighter, yet full-featured alternative with the ability to control other off-camera flashes.
