The Z 9 features intuitive subject detection, thanks to an algorithm that uses deep learning to automatically detect and track a wide range of subjects. Easily track people, pets, birds, automobiles, bikes, train and planes, no matter if your recording video or capturing stills or videos. Auto focus and auto exposure calculations are made by the camera at 120 cycles per second, making it so you can easily track unpredictable subjects like flying birds. Enhanced Eye AF will automatically track the eyes of people, birds, cats and dogs no matter the situation or obstruction.
