Outstanding resolution at ultra-wide 16 mm angles of view

Outstanding resolution in ultra-wide views

Two AA (Advanced Aspherical) lens minimise field curvature and astigmatism for stunning
image-wide resolution at all apertures. One Super ED (Extra-low Dispersion) glass element
and three ED elements suppress chromatic aberration, while an optimised coating
minimises flare and ghosting. This is an ideal lens for creating spectacular wide-angle
images.

The beauty of G Lens bokeh at F1.8

When beautiful bokeh is the goal, this G Lens really delivers with its large F1.8 maximum
aperture, 11-blade circular aperture mechanism, and carefully controlled spherical
aberration.

Eye-opening close-up performance

Close-up performance is excellent with a minimum focus distance of 0.15 m / 0.5 ft and
maximum magnification of 0.25x when using AF (0.13 m / 0.43 ft, 0.30x for MF). The ability
to get that close with an ultra-wide lens makes it possible to capture dynamic perspectives
with deep, exquisite bokeh.

Large-aperture ultra-wide performance in a compact lens

Large-aperture, ultra-wide, and compact

Aspherical lens elements, including Sony’s high-precision AA (Advanced Aspherical) lens,
result in a full-frame ultra-wide lens that is 73.8 x 75 mm (3 x 3 in) and weighs just 304 g
(10.8 oz). It is compact, lightweight, and mobile while delivering spectacular imaging
performance for a wide range of subjects including landscapes, architecture, night scenes,
and more.

Fast, precise autofocus supports high-level imaging

Advanced AF supports high-level imaging

Two XD (extreme dynamic) linear motors ensure fast, precise AF and tracking. A dedicated
control algorithm achieves enhanced response with minimal delay and vibration so that
the lens’s large focus group is driven smoothly and quietly. All of this makes it easier to
capture the most important moments when shooting active, fast-moving subjects.

Refined, stable performance for movies

Focus breathing is controlled so that angle of view shifts are minimised for smooth movie
footage. The breathing compensation function^*1 in compatible α bodies is also supported,
and in-body Active Mode^*2 image stabilisation makes it easy to shoot stable movies while
walking. The lens accepts 67 mm filters, and is compact, lightweight, and easy to balance
on a gimbal.

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.
*2. Compatible models only.

Comprehensive control and solid reliability

Comprehensive control

In addition to the normal focus hold function, other functions can be assigned to the focus
hold button via the camera controls as needed. A focus mode switch conveniently located
on the side of the lens barrel makes it easy to switch between auto and manual focus
without having to take your eye off the viewfinder.

Natural linear manual focus response

Linear Response MF ensures that the focus ring responds directly and linearly to subtle
control when focusing manually. Focus ring rotation translates directly to a corresponding
change in focus, so control feels immediate and precise.

Aperture ring with click ON/OFF switch

An aperture ring provides on-the-fly aperture control, and a click ON/OFF switch optimises
aperture ring operation for different types of shooting. The click stops can be turned ON to
provide tactile feedback when shooting stills, or OFF for quiet, continuous aperture control
when shooting movies.

Iris lock prevents unwanted aperture changes

An iris lock switch prevents unwanted aperture changes while shooting. When locked, the
aperture is either locked at the [A] position or can be rotated between any of the manual
settings.

Extra reliability for outdoor shooting

A dust and moisture resistant design^*3 provides ample reliability when shooting outdoors.
The front element features a fluorine coating that repels contaminants and makes the lens
easier to clean.

Sony's goal: zero environmental footprint

Sony's goal: 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.

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.
*1. As of the February 2025 product announcement.

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.
*2. Sony test conditions. Maximum continuous shooting speed may be lower in some conditions.
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.
*3. For compatibility information see: https://www.sony.net/dics/breathing/
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 SteadyShot^TM

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.
