    Advanced Flash Photography Made Simple

    For stunning flash photography even in complex lighting environments, Canon's new Speedlite 430EX III–RT offers a fantastic combination of advanced features and simple operation. Compact in size, yet powerful in range, the Speedlite 430EX III–RT not only provides a portable light source, it has easy to manage features that can enhance contrast, color temperature, brightness and focus of light for more natural–looking photography. Whether bouncing the light source off a wall or ceiling, using its integrated Catchlight panel to brighten up a subject's face, or using its bounce adapter to soften the intensity of the flash beam, the Speedlite 430EX III–RT is impressively versatile. With convenient custom and personal functions, speedy recycle times and advanced wireless photography options, the Speedlite 430EX III–RT can be an indispensable accessory for photographers ready to take their flash photography to the next level.

    Compact, Portable & Indispensable

    For advanced flash photography on the go, the Speedlite 430EX III–RT is efficiently designed to incorporate a number of options in a compact, lightweight and portable package. It's considerably smaller than its predecessor, has a compact head with a redesigned optical zooming mechanism and, like the 600EX–RT, has a refined exterior for good looks and intuitive operation.

    Power, Over a Wide Range

    The Speedlite 430EX III–RT has a maximum guide number of 141 ft./43m at ISO 100, and flash coverage of 24–105mm, 14mm with its integrated extendable wide panel in use (full–frame). Whether taking portraits or group photos, working close or from a distance, the Speedlite 430EX III–RT has the power to illuminate the subject at hand.

    Simple Advancements for Enhanced Results

    The Speedlite 430EX III–RT incorporates a number of features designed to provide excellent results, simply. Its built–in, extendable Catchlight panel can softly brighten faces for a more natural look and can better capture facial expression. Plus, it helps reflect illumination from the flash onto the subject's eyes. The Speedlite 430EX III–RT's Dot–matrix LCD has a clear, easy to read Graphic User Interface (GUI) so all settings can be seen. Its new, easily operated Control Dial makes selecting and changing flash settings a breeze.

    More Flexibility for Increased Bounce Options

    By aiming the head of the flash at a wall or ceiling, a broad, soft and even illumination can be achieved for more natural–looking photography. The Speedlite 430EX III–RT has an improved bounce range: it can be moved up from 0–90°, can be rotated 150° to the left and 180° to the right. With this flexibility, it's easy to experiment with bounced flash, and to find just the right setup for compelling portraits, still life or other creative photographs.

    Dynamic, Flexible Wireless Functions

    For comprehensive lighting setups on the go, the Speedlite 430EX III–RT offers a number of options for both wireless flash and multi–camera operation. When used with a compatible flash, or flash driver mounted on camera, the Speedlite 430EX III–RT can serve as a slave unit in an optical setup, at distances of up to 49.2 ft./15m (indoors). In addition to optical wireless flash, the Speedlite 430EX III–RT is capable of radio transmitted wireless flash where the flash units need not be in visual proximity to one another and transmission distance is extended up to 98.4 ft./30m. Among cameras with the Speedlite 430EX III–RT attached, setups of up to 15 flash and camera units can be synchronized to take photographs simultaneously, making multi–angle and multi–directional photography setups simple. Additionally, remote shutter release can be achieved when the Speedlite 430EX III–RT is used as a slave unit with a compatible EOS digital SLR.
