Powerful, yet compact enough to take anywhere
A guide number of 43 (m, ISO100) means there’s enough power for most occasions. The Speedlite 430EX III weights just 295g and is only 113.8mm long, so there’ll always be room for it in your bag. Powered by readily-available AA batteries, the flash recycles following a full-power flash in just 3.2s.

Simple controls and an intuitive interface
The controls on the Speedlite 430EX III echo those of many EOS cameras. Shortcut controls give access to key features, and a control wheel allows quick adjustments to be made. A lock switch prevents settings from being changed accidentally. An LCD screen shows settings and shooting information at a glance, and is illuminated for low-light conditions.

Shoot flattering portraits using bounced light
A movable flash head allows light to be bounced from large surfaces, like walls or ceilings, creating soft, shadow-free lighting that’s perfect for portraiture. A built-in reflector panel can be deployed to create sparkling ‘catch lights’ in a subject’s eyes, bringing their expression to life. Fit the included Bounce Adapter to soften the light even more. A coloured filter is also supplied, which aims warm up the colour temperature of the flash’s output so that it more closely matches the colour of indoor ambient lighting. The Speedlite 430EX III can zoom its flash output to match the angle of view of the lens being used.

Wireless flash triggering
The Speedlite 430EX III can be fired while off-camera using optical triggering, giving photographers huge versatility. Optical triggering allows EOS cameras featuring a built-in Integrated Speedlite Transmitter (e.g. EOS 760D, EOS 70D and EOS 7D Mark II) to fire the Speedlite 430EX III-RT from up to 10m away, without the need for extra equipment.
