Helping to reduce the intimidation of flash photography, the Speedlite 470EX-AI from Canon is a unique on-camera light featuring Auto Intelligent Bounce technology. This function measures the room you are working in, along with the set focus distance, in order to automatically tilt and rotate the flash head to produce even, diffuse, and clean bounce flash results. This function can be used in full-auto mode, where the flash automatically determines all settings, or in semi-auto mode, where you can set the angle of the flash and it will automatically rotate depending on the specific camera position or orientation in use.

Beyond its distinct automated capabilities, the 470EX-AI is also distinguished by its apt flash specs, including E-TTL/E-TTL II compatibility, a guide number of 154′ at ISO 100 and 105mm, a zoom head with coverage from 24-105mm, and a pull-out diffuser to widen this coverage to 14mm. Manual stepless adjustment over bounce is possible with a tilting range up to 120° along with +/- 180° rotation, and off-camera triggering is possible using the optical slave mode.
