Sony FE 400mm F4.5 GM OSS Lens

A mobile G Master 400 mm prime you can shoot handheld

G Master image quality and advanced AF combine in a 400 mm prime lens that redefines super-telephoto prime potential. With a compact E-mount body you have a perfectly balanced, mobile system that can capture sharp details when shooting wildlife, sports, trainspotting, and more with unprecedented ease, even when handheld. Explore a new world of super-telephoto freedom.

The compact, lightweight, easy super-telephoto prime

This high-performance 400 mm F4.5 super-telephoto prime lens is the world’s lightest11 at just 994 g (35.1 oz., minus tripod foot). An extraordinary combination of G Master optics and the latest mechanical design achieves remarkably low weight, smooth handling, and minimum fatigue while delivering outstanding image quality when shooting handheld. Overall length is just 242 mm (9-1/2 in.) for outstanding mobility.

Superb G Master sharpness for breathtaking detail

Super ED (Extra-low Dispersion) and ED glass elements in an advanced optical design minimise aberration for high resolution that befits the G Master brand. Sony’s original Nano AR Coating II effectively suppresses flare and ghosting for superior clarity and contrast in backlit conditions. An 11-blade circular aperture and individually optimised spherical aberration contribute to smooth, creamy G Master bokeh.

AF that reliably captures challenging subjects

Two of Sony’s high-thrust XD (extreme dynamic) Linear Motors work with an advanced algorithm to bring out the full AF speed and precision potential of the latest camera bodies. Focus and subject tracking are fast, precise, and quiet. Erratic wildlife movement and sports action are reliably tracked and captured, even when shooting 120 fps bursts with the α9 III body, for example.

Enhanced shooting freedom and control

Optical image stabilisation with selectable modes delivers sharp images when shooting handheld. The lens and a compatible body can work in concert for even more effective stabilisation. Four focus hold buttons and a function ring14 can be customised as needed, while Full Time DMF and Focus Range Limit switches offer flexible focus control. Focal length can be extended to 800 mm with an optional teleconverter.

Reliable in challenging outdoor conditions

A dust and moisture resistant design ensures high reliability in outdoor conditions where light rain and airborne dust might otherwise be a problem. The front lens element features a fluorine coating that prevents contaminants from sticking to the lens surface while making it easier to clean.
