Canon 470EX-AI Speedlite

470EX-AI Speedlite

Canon’s all-new Speedlite 470EX-AI is engineered to change the way you think about flash photography. As the world's first flash with an AI Bounce function (Auto Intelligent)*, the Speedlite 470EX-AI is equipped to detect the distance to your subject as well as the ceiling in order to calculate the ideal angle for the flash to achieve desired results, automatically. The flash head swivels in multiple directions to formulate the ideal bounce flash angle while you simply watch it work.
The Speedlite 470EX-AI can even maintain defined exposure and bounce angles when you’re alternating between horizontal and vertical compositions. In addition, it boasts a powerful maximum guide number of 47 (154 ft./47m) at ISO 100, a zooming flash head and numerous features for versatile and powerful flash photography.
