Polaroid introduces SONAR automatic focusing

Life doesn’t just sit there waiting for you to focus. So Polaroid has invented a way for sonar to focus for you automatically. You press one button and that’s all. Within a split second inaudible sound waves dart to the subject and back, and the lens whips into focus. With Polaroid’s new Sonar OneStep Land Cameras you can get sharp, precisely focused pictures every time. And see them in minutes.
