Canon has just announced the upcoming release of the latest addition to their speedlight lineup – the 430EX III-RT.  While still having the same zoom range (24-105mm) and guide number (141 ft at ISO 100) as the 430EX II, the updated unit is more compact and lightweight (10.41 oz vs. 11.6 oz) with updated controls.
