The iPhone 17 Pro introduces an advanced 8x optical zoom with a 200mm focal length, a first for Apple iPhones. This new telephoto lens, part of a 48MP Pro Fusion camera system, ensures consistent image quality across all rear cameras (main, ultra-wide, telephoto) at 48MP. The optical zoom provides sharper detail and better color fidelity than digital zoom, with an ƒ 2.8 aperture enhancing low-light performance for zoomed shots. Users can easily select zoom levels from 0.5x to 8x within the Camera app.
