A refined, lightweight flashgun with power and capabilities that belie its compact frame, Canon's Speedlite 430EX III-RT improves on prior models with an enlarged display screen, simplified controls and the introduction of radio-based wireless TTL - previously the remit of the much higher priced 600EX-RT.
The 430EX III-RT also boasts optical triggering, a guide number of 43 with 24-105mm coverage, movable head with integral reflecting panel and a 3.
2s cycle time.
All in all, on or off camera the 430EX III-RT is a wonderfully capable tool: Brilliant for portraiture, enormously cost-effective and packed full of photo-making possibilities.
