The A6400 introduces an advanced ‘Real-time Eye AF’, the latest version of Sony’s acclaimed Eye AF technology. Features artificial intelligence-based object recognition to detect and process eye data in real time, resulting in improved accuracy, speed and tracking performance of Eye AF. In all autofocus modes, the camera now automatically detects the eyes of the subject and activates Eye AF with a half press of the shutter button, and when in AF-C or AF-A mode, the preferred eye (left or right) of your subject can be selected as the focus point. Choices include Auto / Right Eye / Left Eye, and a Switch Right / Left Eye function can be assigned to a custom function as well. This exciting new technology completely frees the photographer to focus solely on composition with full trust that focus will be tack, sharp and smart.
