Designed for APS-C mirrorless camera sensors, the black E PZ 16-50mm f/3.5-5.6 OSS II Lens from Sony offers a versatile full-frame equivalent zoom angle of 24-75mm within a compact design. A variable aperture of f/3.5 to 5.6 helps keep the lens's size and weight to a minimum while accommodating most use cases. When the camera is powered off, the lens retracts to just 1.25".
