Canon's mid-range Speedlite flash, the upgraded and more compact 430EX III-RT features dual built-in radio or optical wireless triggering, with the gun acting as either master or slave. It has a new illuminated dot matrix LCD display and a multi-control dial which provides shortcuts to the main functions. Other useful inclusions are a catchlight panel to add extra sparkle to portraits and an orange filter to balance the flash output with ambient tungsten lighting.
