Speedlite 470 EX-AI is world’s first flash equipped with Canon’s new Auto Intelligent function - AI Bounce which takes the guess work out of choosing the right lighting angle so you can focus on creative output rather than set-up.

World’s first AI Bounce does the thinking for you
AI Bounce or Auto Intelligent bounce, calculates and moves the flash head automatically to optimize lighting angles for outstanding images

Why bounce flash?
Direct flash can cause harsh lighting and shadows behind your subject. Bouncing flash off ceilings or walls delivers softer, more evenly distributed light

AI Bounce Full Auto takes away the guess work
In full auto mode, the 470EX-AI finds the optimal bounce angle and the flash head will automatically move to the optimal position

AI Bounce Semi Auto speeds up workflow for advanced shooters
In semi auto mode, the flash head will automatically correct bounce angle as you move between horizontal and vertical shooting

Focus on getting great shots
Stay in the moment and let AI Bounce take care of lighting angle. A simple double press of the shutter button triggers AI Bounce so you can get more shots

Simple and easy to operate
A large rear LCD and intuitive user interface makes choosing the correct settings easy

Optical wireless 
470EX-AI works as an optical wireless receiver for off camera flash shooting when paired with a Canon camera or Speedlite with transmitter function

Strong flash output
Flash distribution range of 24-105m is wide allowing distribution of light to all corners of the picture and powerful enough to shoot with telephoto lenses
