Zoom to 800 mm for the beauty beyond the reach of the naked eye
The FE 400–800 mm F6.3–8 G OSS is Sony's first1 α Lens that zooms to 800 mm, with a range that is ideal for distant subjects as well as the creation of telephoto compression. The fast, precise AF lets you capture subjects that can't be approached closely, such as wild birds and wild animals, and draw them into the full picture. The internal zoom design minimises centre-of-gravity shift for smooth handling.

When going the distance still isn’t enough, you need the right extension to push further. Wildlife photography is all about getting as close as possible, and this lens takes you there—effortlessly.
FEATURES
Go long with the first1 α Lens: 400–800 mm super-telephoto zoom
The FE 400–800 mm F6.3–8 G OSS is the first1 α Lens to cover a 400 mm to 800 mm super-telephoto range. An optional 2x teleconverter can extend maximum focal length to 1600 mm. The internal zoom means the length of the lens does not change, and the centre of gravity stays within a small range for stable handling. Smooth, easy zoom ring rotation allows precise zooming, while careful design prevents accidental focal length changes.
Cutting-edge optical design gives high resolution and natural bokeh throughout the zoom range
Six ED (Extra-low Dispersion) glass elements effectively control chromatic aberration. Flare and ghosting in backlit conditions are also thoroughly suppressed. An 11-blade circular aperture helps to create beautiful ball bokeh amid exceptionally smooth, creamy background bokeh when shooting with a narrow depth of field.
Fast, precise AF captures even fast-moving subjects
Two precision linear motors drive the lens' focus group for fast, accurate focusing. Tracking easily keeps up with the 120 fps1 maximum burst speed of the α9 III, and continues uninterrupted even while zooming so important moments are not lost. A focus-range limiter (FULL/10 m–NEAR/∞–8 m) can be used to optimize operation for different subject distances. Focus breathing is suppressed for refined movie quality and quiet operation expands the gamut of possible applications.

Focus hold buttons offer flexible control
Three focus hold buttons at 90° increments around the lens barrel allow instant focus hold operation in either horizontal or vertical orientations, whether the camera is being held normally or upside-down. Functions other than focus hold can be assigned to the buttons as needed.
Solid support for handheld or tripod-mounted shooting
The optically stabilised FE 400–800mm F6.3–8 G OSS extends to 800 mm, but weighs just 2475 g (87.4 oz) and can be used handheld without shake-induced blur. Stabilisation is even better with an α body that includes image stabilisation. When using a tripod, the mount foot can be quickly rotated for horizontal or vertical orientation. Durable components, optimised balance and a non-removable foot maximise reliability and performance.
High-level control and reliability for any situation
Three focus hold buttons at 90° increments around the barrel allow easy access in any orientation. Other functions can be assigned to the buttons as needed. Internal zoom and a dust/moisture resistant3 design maximise reliability. The front element has a fluorine coating that repels contaminants and makes the lens easier to clean. The lens hood is a new design with a lock button and filter opening for easy operation.
