The new FE 400mm f/2.8 GM OSS is a professional Sony E-mount super telephoto lens with a newly developed XD Linear Motor for extremely fast, precise and quiet AF. The three fluorite lenses offer outstanding resolution and the Sony Nano AR Coating eliminates flare and ghosting. The full-time DMF allows manual focus by simply rotating the focus ring even in AF-C mode.

Sony G-Master series lenses take imaging and expression to previously unattainable levels with a stunning blend of extremely high resolution and softly dissolving background bokeh.

Innovative G Master f/2.8 super telephoto

Sony’s most advanced lens technologies have been unsparingly applied in this large-aperture super telephoto lens, achieving extraordinary speed, outstanding G Master resolution and bokeh, plus professional control and reliability. Moreover, the Sony FE 400mm f/2.8 GM OSS is the lightest super telephoto lens in its class1, providing unparalleled handheld shooting freedom.

Speed that maximises body performance

New XD (extreme dynamic) Linear Motors deliver higher thrust than conventional types, achieving up to a 5x improvement* in moving-subject tracking performance with current and future camera bodies. Two of these new motors and newly developed algorithms quietly drive the lens’s large focus lens group faster and more precisely than ever before. The full speed performance of advanced camera bodies can be applied to capturing dynamic sports or wildlife subjects.

Stunning G Master resolution and bokeh

Extremely high design standards ensure outstanding resolution right out to the image edges. Three fluorite elements minimise chromatic aberration. Spherical aberration is carefully controlled during design and manufacture to achieve the highest possible bokeh quality. Optional high-performance 1.4x and 2.0x teleconverters are supported*, providing outstanding resolution and contrast even at 800mm.
*Maximum aperture with the 1.4x and 2.0x teleconverters is f/4 and f/5.6, respectively.

The world’s lightest at just 2 895g*

An innovative optical design that includes three fluorite elements reduces the number of elements at the front of the lens barrel for a low weight of 2 895g. Durable magnesium alloy components also contribute to reduced weight. Portability and handling are outstanding, and ideal balance affords agile, easy operation whether shooting handheld or on a monopod.

Durability and reliability for challenging conditions

The dust- and moisture-resistant design* provides the reliability needed for outdoor use in harsh conditions. A durable magnesium alloy used for the lens barrel exterior, tripod mount, and interior barrel components achieves tough durability while minimising overall weight. The front lens element features a fluorine coating that helps to keep it clean while making it easier to wipe dirt and fingerprints away.
*Not guaranteed to be 100% dust- and moisture-proof.

Features for professional shooting needs

Full-time DMF allows manual focus to be engaged simply by rotating the focus ring, even while shooting in AF-C mode. Optical image stabilisation is built in, and a new Mode 3* setting features an advanced algorithm that provides optimum stabilisation for dynamic sports action while also making framing easier. Four focus-hold buttons and a focus ring with Linear Response MF further enhance versatility.
*5α9 software must be updated to the latest version to activate Optical SteadyShot MODE 3 when this lens is used with the α9. Refer to the Sony support site for camera body compatibility information.
