The Sony FE 400-800mm f/6.3-8 G OSS is a full-frame, super-telephoto lens for sports, wildlife and bird photography and videos. Dual linear motors help the lens focus quickly and quietly, perfect for fast-moving subjects. The built-in stabilization reduces camera shake, especially at long zooms, for clearer photos. The lens can take a 1.4x or 2x teleconverter to increase the focal length further. For increased lens stability and sharper imagery, a fixed, rotating tripod foot is included on the lens. The lens has a minimum focus distance of 1.7 m (Wide) and 3.5 m (Tele) and weighs 2.47 kg.
