Canon Speedlite 430EX III-RT

Canon Speedlite 430EX III-RT is a Canon hot-shoe speedlight with E-TTL II metering, radio wireless and high-speed sync. It sits below Canon’s larger 600-series flashes, but adds a useful mix of portability and control for event work, portraits and travel kits. The head tilts and swivels for bounce flash, and the built-in wireless system supports both Canon RT radio control and optical wireless use, which makes it flexible as a master or slave unit in compatible setups. At 43 m guide number at ISO 100, it has enough output for general on-camera and bounced-off-ceiling work without becoming as bulky as the top-end units. Power comes from four AA batteries, so running costs are low and spares are easy to source. In use it is light enough to keep on-camera for long sessions, yet still feels like a proper Canon accessory with sensible controls and a compact body. When buying used, check the flash tube for cracks or discoloration, confirm the hot shoe foot locks securely, test the zoom head and tilt/swivel movement, and make sure the battery contacts are clean with no corrosion or leakage damage.
