The Sony FE 300mm f/2.8 GM OSS is a fast telephoto prime characterized by an impressively lightweight, portable design. The 300mm f/2.8 design excels for photographing indoor sporting events as well as close-range events, journalism, and even wildlife subjects. As part of Sony's esteemed G Master series, this lens is designed to achieve a balance of impressive resolution and sharpness along with distinctive and pleasing bokeh. Nano AR Coating II has been applied to interior lens surfaces to suppress reflections that cause flare and ghosting. A dual XD (Extreme Dynamic) Linear Motor System quietly and quickly focuses on fast-moving subjects while shooting at high speeds. Full-time DMF supports manually adjusting focus simply by turning the focusing ring, regardless of the focusing mode, and Linear Response MF provides a natural and responsive focus feeling for more precise manual control. Optical SteadyShot image stabilization compensates for the effects of camera shake to better enable making sharp shots when working handheld. Three different stabilization modes can be used depending on the shooting situation: Mode 1 for general shooting, Mode 2 for panning shooting, and Mode 3 prioritizes accurate framing when photographing and tracking fast and erratically moving subjects. Measuring about 3.2 lb without the tripod mount, this 300mm f/2.8 has a truly lightweight design that suits handheld shooting applications and benefits those carrying multiple lenses and camera setups at an event. Compared to the FE 400mm f/2.8 GM OSS, this lens is around 50% lighter and 43% smaller. In addition to the weight-saving optical design that limits extra elements, the internal components of the lens also are made from lightweight yet durable magnesium alloy.
