Sony SEL400F28GM FE 400mm F2.8 GM OSS Lens

Product Highlights

• Innovative G Master F2.8 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 SEL400F28GM is the remarkably lightweight super telephoto lens, providing unparalleled handheld shooting freedom.
• Newly developed XD (extreme dynamic) Linear Motor achieves extremely fast, precise, quiet AF :The XD Linear Motors used in the SEL400F28GM have been newly developed to deliver higher thrust and efficiency than conventional types in order to make the most of the rapidly evolving speed performance of current and future camera bodies. Linear motor design and component layout have been thoroughly revised to achieve significantly higher thrust. Two of these new motors are used in the SEL400F28GM, achieving up to a 5x improvement2 in moving-subject tracking performance. This means that the full speed performance of advanced camera bodies can be applied to capturing perfect images of the most dynamic sports or wildlife subjects.
• Extraordinary G Master resolution : 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. The optical design includes three fluorite elements that help to minimize axial chromatic aberration that can be a problem in large-aperture lenses, as well as lateral chromatic aberration that can reduce resolution towards the image periphery. Colour bleeding is effectively suppressed, allowing clear reproduction of the finest subject details.
• Natural, beautiful G Master bokeh : In addition to careful control of spherical aberration at the design stage, each lens is individually tested and adjusted during manufacture to achieve the highest possible bokeh quality. An 11-blade circular aperture mechanism further contributes to smooth circular bokeh. The SEL400F28GM allows the narrow depth of field achievable with a 400mm F2.8 lens to be utilized to create images with deep, lush, defocused backgrounds.
• Dust and moisture resistance5 maintains reliability in harsh environments : Dust and moisture resistant design provides the reliability needed for outdoor use in harsh conditions.
