Sony FE 400mm f/2.8 GM OSS Lens

Speed that maximizes body performance 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 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 minimize chromatic aberration. Spherical aberration is carefully controlled during design and manufacture to achieve the highest possible bokeh quality. Durability and reliability for challenging conditions 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 minimizing overall weight. The front lens element features a fluorine coating that helps keep it clean while making it easier to wipe dirt and fingerprints away. 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 stabilization is built-in, and a Mode 3 setting features an advanced algorithm that provides optimum stabilization for dynamic sports action while also making framing easier. Four focus hold buttons and a focus ring with Linear Response MF further enhance versatility.
