Sony FE 400mm F2.8 GM OSS Super-Telephoto Prime Lens

The Sony SEL400F28GM is a super-telephoto prime lens for full-frame E-mount cameras that brings distant subjects into clear view with a 400 mm field of view. Designed for professional sports and wildlife work, it offers reach, speed, and imaging quality in a single package.

An f/2.8 maximum aperture gathers ample light, keeping shutter speeds high in dim stadiums or shaded forests. The wide opening also produces a shallow depth of field, while an 11-blade circular diaphragm turns background highlights into smooth, rounded bokeh that helps a subject stand out.

Inside the optical path, three fluorite elements and Sony Nano AR coatings work together to suppress chromatic aberration, ghosting, and flare. The result is crisp detail and accurate color, even when shooting against bright backlighting or heat haze on a summer afternoon.

Autofocus performance comes from Sony’s XD Linear Motor system, which moves focus groups quickly and quietly. Photographers can track a sprinter accelerating off the blocks or a bird lifting from a branch without distracting mechanical noise. Built-in Optical SteadyShot adds up to five stops of stabilization, making it possible to work handheld or pan smoothly from a monopod.

The lens body uses magnesium alloy that keeps overall weight to 6.4 lb and stands up to professional use. Weather sealing protects the internal optics from dust and moisture, a benefit when covering a rainy soccer match or waiting in humid wetlands. A 40.5 mm drop-in filter slot simplifies the use of polarizers or neutral density filters without disturbing the front element.
