A powerful, compact wireless flash designed for creative lighting on and off camera

The Canon Speedlite 430EX III-RT is a versatile external flash built for photographers who want reliable power, intuitive control, and advanced wireless functionality in a compact design. Compatible with Canon E-TTL and E-TTL II, it integrates seamlessly into the EOS system for consistent, accurate flash exposure.

Powerful Performance in a Compact Body

With a Guide Number of 43m (ISO 100), the Speedlite 430EX III-RT delivers enough power for a wide range of shooting situations. Despite this output, it remains highly portable at just 295g and 113.8mm in length, making it easy to carry in any camera bag.

Powered by four AA batteries, the flash offers fast recycling, returning to full power in approximately 3.2 seconds, with a recycle time range of 0.1–3.5 seconds.

Advanced Wireless Flash Control

The Speedlite 430EX III-RT supports both 2.4 GHz radio transmission and optical triggering, offering flexible off-camera lighting options.

• Radio triggering allows control from up to 30m without line of sight
• Optical triggering works up to 10m using compatible EOS cameras or optional transmitters
• Supports master and slave operation
• Control up to 15 flashes, organised into 5 groups across 15 channels
• Optical mode supports unlimited flashes across 4 channels and 3 groups

This dual system makes it easy to integrate into existing Speedlite setups.

Intuitive Controls and Clear Display

The control layout mirrors that of EOS cameras for a familiar shooting experience. Shortcut buttons and a multi control dial allow quick adjustments, while a lock switch prevents accidental setting changes.

A rear LCD panel displays shooting information clearly and includes backlighting for low-light environments.

Flexible Light Shaping for Portraits and Events

The flash head tilts up to 90° and rotates 150° right and 180° left, allowing light to be bounced off walls or ceilings for softer, more flattering illumination.

Additional features include:

• Built-in bounce panel for catchlights
• Included bounce adapter for softer light
• Colour filter to better match indoor ambient lighting
• Zoom range of 24–105mm (14mm with panel) to match lens coverage
• Light distribution modes: Standard, Guide Number Priority, and Even Coverage

High-Speed Sync and Precision Control

The Speedlite 430EX III-RT supports:

• High-speed sync
• First and second curtain sync
• Exposure compensation of ±3 EV in 1/3 or 1/2 stop increments
• AF assist beam with a range of up to 13.1 ft
• 10 custom functions and 8 personal functions

Fresh batteries provide approximately 180 full-power flashes.
