Speedlite 470EX-AI: Automatic Bounce Flash

Shot with AI BOUNCE Take Hold of the Beauty of Bounce Flash Photography

Bounce flash photography may be difficult to master, but the Speedlite 470EX-AI takes the guesswork out with its incredible AI Bounce function*. By calculating the optimal bounce angle and moving itself into place, the Speedlite 470EX-AI can determine both the appropriate camera exposure and flash output for beautiful and natural photography. The bounce settings you’ve selected can also be automatically maintained when switching from horizontal to vertically oriented compositions, helping you stay ready for the ideal shot.

Master Bounce Flash Photography with Ease

AI.B Full-auto mode helps make bounce flash photography fast and easy by taking the guesswork out of setting up and automatically creating a brilliant light source for the situation at hand. First, it fires a preflash to calculate the distance from the flash to the subject, then points the flash head up to determine ceiling height up to 23 feet. Using this information, the Speedlite 470EX-AI determines the optimal bounce angle and exposure parameters before moving itself into an ideal position to capture just the right amount of illumination.

Push Your Bounce Flash Creativity Further

For seasoned flash photographers, the AI.B Semi-auto mode can maintain the specified bounce angle when the camera's orientation is changed. This means you can store the bounce angle you’ve defined in the flash’s memory, and can direct the flash to recreate that angle when switching between vertical and horizontal compositions. Registered bounce settings are then easily restored by simply pressing the shutter button twice. AI.B Semi-auto can be a huge time saver, enabling you to focus on the your subject and composition without having to return to flash settings every time the camera’s orientation changes. It also lets you experiment with creative lighting, such as bouncing the flash off the wall, while still providing beautifully natural results.

Press the "ANGLE SET" button to store the angle.



The Speedlite 470EX-AI automatically maintains the optimal bounce angle even when the camera’s orientation or angle of view is changed.

Even if you switch your camera between horizontal and vertical orientation…
… the Speedlite 470EX-AI will compensate to maintain the optimal angle so you get the results you want.
