Panasonic LUMIX S PRO 70-200mm F4 O.I.S. L Mount Camera Lens

It offers a constant f/4 maximum aperture, maintaining consistent illumination throughout the zoom range. One aspherical element and one ultra-high refractive index element help minimize distortions and spherical aberrations, ensuring edge-to-edge sharpness and illumination. This lens also features a dual AF system with linear stepping motors, optical image stabilizer, weather-sealed construction, and a removable, rotating tripod collar. With three ED elements and one UHR element, chromatic aberrations and color fringing are greatly reduced, producing a high degree of clarity. This lens can also be used with APS-C models, providing a 105-300mm equivalent focal length range.
