AF Assist Beam for
Low-light Focusing

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.

Intermittent Flash

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.

Flash Exposure
Adjustment Range

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.
