Canon Speedlite 430EX III-RT

Pop-up flash and high ISO only go so far indoors. The Speedlite 430EX III-RT gives you a proper bounce-capable flash with a guide number of 43m at ISO 100, in a body small enough to stay on the camera all evening at a wedding reception, party or corporate event.

The head tilts up 90° and swivels 150° left and 180° right, so you can bounce light off ceilings and walls for soft, natural-looking results instead of harsh direct flash. Coverage zooms from 24 to 105mm, with a pull-out wide panel for 14mm, while E-TTL II metering handles exposure and high-speed sync allows wide apertures in daylight.

The real advantage is the built-in 2.4GHz radio. The 430EX III-RT can act as a master or a slave in Canon’s RT system, controlling up to 15 slave units at around 30m without needing line of sight, and it still works as an optical slave with older setups. Four AA batteries deliver recycle times from 0.1 to 3.5 seconds.
