Sony FE 400mm f/4.5 GM OSS Lens - Sony
Loading product options
This high-performance Sony FE 400mm f/4.5 GM OSS Lens is the world’s lightest 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.
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.
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*2 with the α9 III body, for example.
2. Sony tests. Maximum continuous shooting speed may be lower in some conditions.
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.*3 Four focus hold buttons and a function ring*4 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.*5
3. Refer to Sony’s support site for compatible camera body info: https://www.sony.net/dics/fnc1002/
4. Functions that can be assigned to the Function Ring will depend on the camera used. Refer to the corresponding camera Help Guide for details. Some functions may not be available with some cameras; in such cases Power Focus is assigned by default.
5. SEL14TC and SEL20TC teleconverters supported.
A dust and moisture resistant design*6 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.
*6. Not guaranteed to be 100% dust and moisture proof.
