Description
A super-telephoto zoom G Lens™ that expands the limitation of telephoto expression
The FE 400-800mm F6.3-8 G OSS is Sony’s first*1 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.
Versatile zoom lens covering 400mm to 800mm
E-mount 400-800 mm super-telephoto zoom
The FE 400-800mm F6.3-8 G OSS is the first*1 α Lens that covers the 800 mm super-
telephoto zoom range. Optional 1.4x and 2x teleconverters are available, with the 2x
teleconverter able to extend that range up to 1600 mm. Super-telephoto focal lengths are
ideal for birds and wildlife, sports, aircraft, and other subjects that can’t be approached
closely, as well as scenes that benefit from telephoto compression.

Internal zoom and optimised zoom control
Internal zoom means the length of the lens does not change while zooming, and the center
of gravity stays within a small range for stable handling. Smooth, easy zoom ring rotation
allows quick zooming to any focal length in the range, while careful design reduces the
possibility of accidental focal length changes.
High image quality that enables unique super-telephoto expression
Superb quality throughout the zoom range
Six ED (Extra-low Dispersion) glass elements effectively control chromatic aberration that
can be a problem at super-telephoto focal lengths. Flare and ghosting are also thoroughly
suppressed. An 11-blade circular aperture helps to create beautiful ball bokeh amid
exceptionally smooth background bokeh when shooting with a narrow depth of field.
1.7 m minimum focus at 0.23x magnification
Offering remarkable close-up capability for a super-telephoto zoom, the FE 400-800mm
F6.3-8 G OSS features a minimum focusing distance of just 1.7 m (5.58 ft) at the wide end
of the zoom range and a maximum magnification of 0.23x. This level of close-up
performance dramatically expands the potential uses of this versatile lens.
Fast and precise AF for both stills and movies
Fast, precise AF captures quick subjects
Two precision linear motors drive the lens’s focus group for fast, accurate focusing.
Tracking easily keeps up with the 120 fps*2 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.

Continuous shooting speed may vary in the AF-C focus mode.
Precise manual focus
Full-time DMF automatically engages manual focus when the focus ring is operated,
making it easy to apply fine manual adjustments or change the focus entirely. Linear
Response MF ensures that the focus ring responds directly to manual focus control, with
focus ring rotation translating directly to a corresponding change in focus.
Minimal focus breathing for movies
Advanced lens technology reduces focus breathing as well as focus and axial shift when
zooming. Changes in angle of view and other image shifts are minimised for smooth, high-
quality movie footage. The breathing compensation function*3 provided in compatible α
bodies is also supported, further reducing unwanted image shifts while focusing.

Not available when shooting stills.
Angle of view and image quality may change slightly when this function is used. Effective compensation
may not be achieved in all situations.
Built-in Optical SteadyShotTM
Shooting handheld at super-telephoto focal lengths is made easier by the built-in Optical
SteadyShot image stabilisation. MODE 2 is ideal for panned shots, while MODE 3*4 provides
improved viewfinder stabilisation for easier framing of active subjects. Even better
stabilisation plus enhanced body-lens communication and control are available when used
with compatible α bodies*5.
*4. MODE 3 is supported by the latest body software version. Please refer to the appropriate support web
pages for information on body compatibility.
*5. Please refer to the support page https://www.sony.net/dics/fnc1002/ for details of compatible
cameras. Correction effect depends on the lens.
Operability and reliability
Durability and ease for tripod shooting
The tripod mount foot provides 1/4-20 UNC and 3/8-16 UNC screw sockets for
compatibility with a wide range of tripods, and can be quickly rotated for horizontal or
vertical orientation. Durable components, optimised balance, and a non-removable design
maximise reliability and performance in challenging conditions.
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.
Extra reliability for outdoor shooting
Internal zoom coupled with a dust and moisture resistant*6 design provide ample reliability
when shooting outdoors. The front element features a fluorine coating that repels
contaminants and makes the lens easier to clean. The lens hood is a new design with a lock
button for easy attachment and removal, and a filter opening for easy operation.

Social responsibility
Environmentally conscious
Sony's environmental plan "Road to Zero" aims for a zero environmental footprint by 2050. The environmental footprint of this product has been minimised from development through supply chain, production, and packaging. We are also transitioning to non-plastic packaging materials. Plant-based non-woven fabrics are used for product bags.
