Sony FE 400-800mm f/6.3-8 G OSS Lens

Go long with the first¹ α Lens: 400-800 mm super-telephoto zoom

The FE 400-800mm 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 the 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’s focus group for fast, accurate focusing. Tracking easily keeps up with the 120 fps² maximum burst speed of the α9 III, and continues uninterrupted even while zooming so important moments are not lost. A focus-range limiter (FULL / 10m-NEAR / ∞-8m) can be used to optimise operation for different subject distances. Focus breathing is suppressed for refined movie quality and quiet operation expands the gamut of possible applications.

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-resistant 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.

FAQs

1. Can I use a teleconverter with the Sony FE 400-800mm lens?

Yes, this lens is compatible with Sony's optional 2x teleconverter, which extends your maximum focal length to an incredible 1600mm.

2. Is this lens suitable for handheld shooting?

Absolutely. Despite its massive reach, it weighs just 2475g and features an internal zoom and Optical SteadyShot (OSS) to ensure stable, shake-free handheld operation.

3. Does the lens extend when zooming?

No, it features an internal zoom design. The physical length of the lens does not change, meaning the centre of gravity remains stable for better handling on a gimbal or tripod.

4. How fast is the autofocus on this super-telephoto lens?

Powered by two precision linear motors, the autofocus is remarkably fast and precise. It is designed to easily track subjects and keep up with the 120 fps maximum burst speed of the Sony α9 III.

5. Is the lens weather-sealed for outdoor use?

Yes, it features a dust and moisture-resistant design, alongside a fluorine coating on the front element to repel water, oil, and other contaminants.

Applications

* Wildlife Photography: Capture birds in flight or timid wildlife from a safe distance without compromising on sharpness or autofocus speed.

* Sports & Action: Track fast-moving athletes across large fields or tracks, utilising the 120 fps-compatible autofocus and focus-range limiter to lock onto the action.

* Aviation & Airshows: Easily pan and track fast aircraft with the stable centre of gravity and built-in Optical SteadyShot.

Care Instructions

• Wipe the fluorine-coated front element gently with a clean, dry microfibre cloth to remove fingerprints, oil, or dust.
• Ensure the lens mount is kept clean and free of debris when changing lenses in the field.
• While the lens is dust and moisture resistant, avoid prolonged exposure to heavy rain or extreme environmental conditions without a dedicated camera rain cover.
