World's lightest 400mm F2.8 super-telephoto lens - The remarkable light weight and excellent balance of the FE 400mm F2.8 GM OSS lens - weighing it at only 6.38 lbs. - is achieved through an innovative optical design that includes three fluorite elements as well as the liberal usage of durable magnesium alloy components
XD (extreme dynamic) Linear Motors for fast, precise, quiet AF - To make full use of the rapidly evolving performance speed of modern and future camera bodies, the lens's focus group is driven by two - newly developed - XD (extreme dynamic) Linear Motors that achieve higher thrust and efficiency than conventional types of AF drive motors
G Master quality with superior focusing speed up to 20fps - All lenses bearing the G Master brand are designed to extremely high standards, ensuring that outstanding contrast at high spatial frequencies is maintained right out to the image edges.
3x fluorite elements, 1x ED glass element reduces flare and ghosting - Based on a new optical design that conforms to stringent G Master standards, the FE 400mm F2.8 GM OSS includes three fluorite elements and one ED (Extra-low Dispersion) glass element that help to reduce chromatic aberration, a common problem in telephoto lenses.
Wide F2.8 max aperture - The wide F2.8 max aperture maintains exposure and depth of field while also allowing maximum light for shooting in almost any condition.
11-blade circular aperture contributes to gorgeous bokeh - Complementing the wide F2.8 aperture are the 11-blade circular aperture blades that result in soft-edged bokeh that is a hallmark of the Sony G Master series.
Nano AR Coating - Sony's original Nano AR Coating is applied to interior lens surfaces to effectively suppress reflections that can lead to flare and ghosting, significantly enhancing image clarity and contrast.
Optical SteadyShot image stabilization significantly reduces blur - High-performance Optical SteadyShot image stabilization is built right into the lens for sharp, blur-free images with a wide range of subjects and handheld shooting.
