Sony's most advanced lens technologies have been unsparingly applied in the SEL400F28GM 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.
Speed that Maximizes 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 minimize 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 tele-converters are supported, providing outstanding resolution and contrast even at 800mm.
Remarkably Lightweight at Just 102.2 Ounces (2,895 grams)
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 2,895 grams (102.2 ounces). 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
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 to 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 new 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.
