Sony Introduces the Long-Awaited 400mm F2.8 G Master Prime Lens

Sony today announced the highly anticipated FE 400mm F2.8 GM OSS large aperture super-telephoto prime lens (model SEL400F28GM).

The product of extensive research and testing, Sony's new FE 400mm F2.8 GM OSS lens is the first large aperture super-telephoto prime to join the E-mount line-up. This exciting new lens produces brilliant image quality, extraordinary focusing speed and precision while also boasting the lightest weight in its class[i] and an extremely balanced design. It's the ideal choice for professional sports, wildlife and nature photographers, and a perfect complement for Sony's extensive line-up of high-speed E-mount bodies including 9, 7R III and more.

World's Lightest 400mm F2.8 Prime with Ideal Balance for Monopod or Handheld Shooting

Weighing in at only 2897g, the new FE 400mm F2.8 GM OSS lens provides a level of portability and handheld manoeuvrability that has never before been achieved in a lens of its class. The remarkably light weight of this lens is achieved through an innovative optical design that includes three fluorite elements, with a reduced number of elements deployed at the front of the barrel, as well as the liberal usage of durable magnesium alloy components.

Additionally, repeated field tests and evaluation by professional photographers across the world have led to a lens design that is not front-heavy, reducing moment of inertia that resists rotation by up to 50% as compared to the SAL500F40G.[ii] This ensures that quicker, more precise panning is available, whether shooting handheld or on a monopod.

Fast, Precise Autofocus

To best take advantage of the rapidly evolving shooting and focusing speeds of Sony's latest cameras, the FE 400mm F2.8 GM OSS lens features two newly developed high-speed XD (extreme dynamic) Linear Motors that drive the lens' focus group, achieving up to a 5x improvement[iii] in moving-subject tracking performance. These motors are supported by specially developed motion algorithms to minimise lag and instability and control noise levels, resulting in exceptionally quick, accurate and quiet autofocus performance. This allows the lens to capture dynamic, fast moving athletes or wildlife with ease.

G Master Image Quality and Bokeh

A member of the Sony's flagship G Master Series lenses, the new large aperture super-telephoto prime lens features an incredible level of image quality and detail, with outstanding contrast and resolution maintained all the way to the corners of the image. The unique optical design includes three fluorite elements that help to minimise chromatic aberration and suppress any amount of colour bleeding. The lens has also been coated with Sony's original Nano AR coating to suppress any unwanted reflections, glare, or ghosting.

In addition to the impressive resolution, the lens features an 11-blade circular aperture mechanism that allows it to produce extremely natural and beautiful background defocus or bokeh'. Each lens is also individually tested and adjusted at manufacturing stage to achieve maximum image quality and bokeh'.

The new FE 400mm F2.8 GM OSS is compatible with Sony's 1.4x and 2.0x E-mount tele-converters, producing outstanding imaging performance at extended focal lengths[iv] while maintaining fast, precise AF performance.

Durability, Reliability and Control

To withstand the harsh conditions of sporting events and wildlife photography, Sony's new FE 400mm F2.8 GM OSS is built with a durable magnesium alloy and a strong, lightweight carbon fibre hood. The lens is also dust and moisture resistant[v], and its front element is coated with fluorine to resist dirt and fingerprints.

There is also an ample amount of hard controls on the lens, including a Full-Time DMF' switch to immediately engage manual focus at any point, customisable focus hold buttons in four different locations on the lens barrel - allowing easy access of an Eye AF for example, and a focus ring that features Linear Response MF for fine, responsive manual focus. The new lens also features built-in optical stabilisation for dynamic sports action and three different Mode' settings, including a brand new Mode 3[vi] setting with an advanced algorithm that ensures easier framing when following moving subjects. The new model includes a function ring with selectable Preset' and Function[vii]' settings, further adding to the customisability, a first for any Sony lens.

The FE 400mm F2.8 GM OSS includes a drop-in filter slot[viii] that accepts 40.5mm ND and other filter types, as well as the optional VF-DCPL1 Drop-in Circular Polarising Filter. The VF-DCPL1 filter can be rotated to achieve the desired polarisation while installed in the lens.

9 System Software Update to Support FE 400mm F2.8 GM OSS[ix]

The latest system software update (Version 3.00) for 9 (ILCE-9) provides support for the new FE 400mm F2.8 GM OSS (SEL400F28GM) lens to optimise optical image stabilisation performance and enables continuous shooting with auto focus tracking even when aperture is greater than F11.

The update also provides added option to input camera serial number to the Exif data, a feature that has been strongly requested by professional sports photographers and photojournalists. Additionally, several other updates to the 9 camera have been implemented with the new firmware, including improved auto focus speed in low light conditions, enhanced continuous AF performance when tracking a moving subject, and reduced release time lag when shooting with flash.

Pricing and Availability

Built to order, the new FE 400mm F2.8 GM OSS will ship in Europe in September 2018,priced at approximately 12,000. The optional Drop-in Circular Polarising Filter (model VF-DCPL1) will ship in Europe in December 2018, priced at approximately 480.
