In addition to its ground-breaking AI Bounce feature*, the Speedlite 470EX-AI is a remarkably agile and high-performing flash. From its powerful light output to its AF assist beam for low-light focusing, the Speedlite 470EX-AI is equipped with numerous features for versatile flash photography.
Maximum Guide Number of 47 (154 ft./47m), Wide Zoom Range of 24–105mm**
Boasting the power and flexibility for numerous shooting situations in a compact and lightweight package, the Speedlite 470EX-AI has a guide number of 47 (when focal distance is at 105mm) and a broad flash distribution range of 24-105mm**.
AF Assist Beam for
The Speedlite 470EX-AI is designed to help achieve sharp focus, especially in situations where the camera’s AF system may experience difficulties.
Infrared Beam System
When you need to be more discreet, using the infrared beam can ensure sharp focus by emitting a steady infrared beam toward the subject, even during bounce shooting.
The Speedlite 470EX-AI emits a small series of flashes. Since illumination reaches the entire picture area, this AF-assist beam mode is effective when a peripheral AF frame is chosen.
To help you change the balance of light between subject and background to your liking, the Speedlite 470EX-AI's exposure is adjustable within a range of ±3 stops in 1/3 or 1/2 step increments. A dedicated dial makes it fast and easy to make these adjustments on the fly.
Flash Angle Range
The Speedlite 470EX-AI has a flexible and wide bounce angle range of up to 120° upward and 180° horizontally. With AI Bounce, angles within this range can be maintained regardless of camera orientation.
Wireless Receiver Function
With wireless flash, ambitious lighting setups can be created almost anywhere, without the need for extra power sources or connecting cables.
Off-camera flash is quick and easy with the Speedlite 470EX-AI, which can serve as a receiver unit as part of an optical wireless flash setup at distances of up to 49.2 ft./15m (indoors).
Soft Lighting with a Bounce Adapter

Ideal for providing diffused soft light, the Speedlite 470EX-AI’s Bounce Adapter SBA-E4*** helps ensure even more natural-looking, detailed images with suppressed shadow effects. Bundled with the Speedlite 470EX-AI, the Bounce Adapter SBA-E4 can be an indispensable tool for portraits and group photographs.
Distribute Light to All Corners with the Wide Panel
The Speedlite 470EX-AI’s wide panel expands coverage even further. Especially suitable for use with an ultra-wide angle lens, this wide panel provides diffused light distribution for focal lengths as wide as 14mm (with 35mm full-frame sensor), minimizing vignetting even in the corners of the composition.
