Sony FE 400mm f2.8 GM OSS Lens

Superlative G Master quality in the world’s lightest 400mm F2.8 Lens. Using two newly developed XD (extreme dynamic) Linear Motors for fast, precise autofocus, the Sony FE 400mm F2.8 GM OSS Lens takes full advantage of the world’s fastest cameras. Reaching speeds up to 20fps with the 24MP a9 and up to 10fps with the 42.4MP a7R III and 24.2MP a7 III.

Speed That Maximizes Body Performance

The 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. The two 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 action sports or wildlife subjects.

Stunning G Master Resolution and Bokeh

The extremely high design standards ensure outstanding resolution out to the image edges. Three fluorite elements help minimize chromatic aberration. Carefully controlled spherical aberration during design and manufacture to achieve the highest possible bokeh quality. Supported are optional high-performance 1.4x and 2.0x tele-converters, providing outstanding resolution and contrast at 800 mm. 

Remarkably Lightweight at 102.2 oz

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 102.2 oz (2,895 g). 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 new design is dust and moisture resistant making it reliable for use in outdoor conditions. With a durable magnesium alloy on the lens barrel exterior, tripod mount, and interior barrel components this achieves tough durability while minimizing weight. The fluorine coating located on the front helps to keep it clean, and make it more easy to wipe away fingerprints.

Features for professional shooting needs

The full-time DMF allows for manual focus to be engaged by rotating the focus ring, even while in AF-C mode. Optical image stabilization built in, with a new Mode 35 setting which features an advanced algorithm that provides optimum stabilization for sports action while also making framing easier. With four focus-hold buttons and a focus ring with Linear Response MF to further enhance versatility.
