Sony FE 400mm f/4.5 GM OSS Lens (Sony E) + Lens Bundle Bonus

Overview

The Sony FE 400mm f/4.5 GM OSS Lens brings genuine super-telephoto reach to the Sony E-mount system in one of the most portable 400mm primes available for full-frame E-mount cameras. Part of Sony's G Master line, it pairs a bright f/4.5 maximum aperture with a Dual XD Linear Motor autofocus system and built-in Optical SteadyShot stabilization, making it a natural choice for wildlife photographers and sports shooters who need to work handheld for long stretches. A dust and moisture-resistant build with a fluorine-coated front element means it can be pushed hard in the field without extra precautions.

At just 24.2 cm long and 994 g, the lens feels closer in hand to a 70-200mm f/2.8 than a traditional super-telephoto prime, and its removable, rotating tripod foot keeps that low weight available for handheld shooting whenever a tripod isn't practical. Continuous autofocus and exposure tracking up to 120 fps supports fast-moving subjects from football sidelines to birds in flight, while full-time manual focus override and a customisable function ring give experienced shooters direct control when they need it.

Built for Long Handheld Sessions

A single front element shifts the lens's centre of gravity back toward the camera body, giving it a well-balanced feel that makes extended handheld shooting far less tiring than a typical 400mm prime. Compared with the Sony FE 400mm f/2.8 GM OSS, this f/4.5 version is 1.9 kg lighter and 11.7 cm shorter, without giving up the reach or optical fidelity the G Master name promises.

Dual XD Linear Motor Autofocus

Two XD (extreme dynamic) linear motors drive fast, quiet and precise autofocus, with continuous AF and AE tracking supported at shooting speeds up to 120 fps. An internal focusing design keeps the lens's overall length constant during use, and full-time manual focus override lets you fine-tune focus at any point without switching modes.

Three-Mode Optical SteadyShot

Built-in Optical SteadyShot image stabilization helps deliver sharp handheld images even at this focal length, with three selectable modes to suit the shooting situation. A focus range limiter and four focus hold buttons around the barrel add further control over autofocus responsiveness.

• Mode 1: standard stabilization for general handheld shooting.
• Mode 2: panning mode for subjects moving across the frame.
• Mode 3: tuned for erratically moving subjects.

G Master Optical Performance

Sony reserves the G Master badge for lenses that meet its highest standards for sharpness, bokeh quality and responsiveness. Super ED and ED glass elements suppress chromatic aberration for high edge-to-edge sharpness even wide open, while Nano AR Coating II controls flare for rich contrast and colour across a range of lighting conditions. An 11-blade rounded diaphragm produces smooth, circular bokeh with gentle focus falloff for clean subject separation.
