CANON SPEEDLITE 430EX III-RT £269/$249

Mid-range but feature-rich, complete with a built-in wireless RF transceiver

The mid-range 430EX II was a top-seller, packing powerful performance into a compact yet robust build, all at an attractive price. The headline upgrade in the more recent III-RT is that, like Canon’s range-topping 600 RT series of Speedlites, it adds a built-in RF (Radio Frequency) transceiver. So whereas the previous model could only act as a wireless slave with an infrared range of around five to eight metres, the new model can act as an RF master or slave with a transmission range of about 30 metres in master mode. That’s when using it in the camera’s hotshoe to trigger other ‘RT’ compatible flashguns.

Another improvement over the previous edition is that the control panel and menu system are redesigned. They’re much more user-friendly and intuitive, for quicker and easier operation. Similarities to the Mk II include a motorized 24-105mm zoom head, with 0-90 degree bounce and 150/180 degrees of swivel to the left and right. The accessories include the usual carrying pouch and stand, but adds a high-quality diffusion dome and tungsten colour-matching filter.

Performance

We’re used to seeing excellent TTL accuracy with own-brand Canon Speedlites and the 430EX III-RT is no exception. With four batteries instead of two, recycling speed is better than from the EL-100, despite the greater max power rating. Even so, our measured max output at the long end of the zoom range is a little down on most other flashguns on test.
