Professional 100-400mm Telephoto Reach

The broad 100-400mm focal-length range makes this Sony G Master lens remarkably versatile. At 100mm, you can frame relatively close subjects while maintaining useful working distance. At 400mm, the lens provides substantial magnification for wildlife, sports and other distant subjects.

For photographers who regularly work outdoors, this flexibility can reduce the need to carry several different telephoto lenses. The 100-400mm range is particularly useful when subjects move unpredictably or when you need to quickly change your composition without changing lenses.

G Master Optical Performance

Sony’s G Master engineering gives the FE 100-400mm F4.5-5.6 GM OSS the optical performance expected from a professional telephoto lens. Its optical construction uses 16 elements in 22 groups, including ED and Super ED elements designed to help suppress chromatic aberration.

The result is detailed imagery with strong clarity across the zoom range. Sony also incorporates Nano AR Coating, which helps reduce flare and ghosting when shooting in challenging lighting conditions.

Beautiful Background Separation

The lens features a 9-blade circular aperture, helping produce smooth, natural-looking defocused backgrounds. This can be especially useful when photographing birds, wildlife, athletes and other subjects where separating the subject from a distracting background is important.

The telephoto perspective can also help compress backgrounds and create a strong visual connection between the subject and its surroundings.

Fast and Precise Autofocus

Capturing fast-moving subjects requires responsive focusing, and the SEL100400GM is engineered for demanding autofocus applications. Its combination of double linear motors and Direct Drive SSM (DDSSM) provides fast, accurate and responsive focus operation.

This makes the lens well suited to wildlife photography, sports photography and other situations where subjects can move quickly and unpredictably.

The lens also includes focus-hold buttons that can be customised through compatible camera menus, giving photographers additional control while shooting.

Optical SteadyShot for Handheld Shooting

Built-in Optical SteadyShot image stabilisation helps minimise the effects of camera shake when shooting handheld. This is particularly valuable when working at longer focal lengths, where even small movements can become more noticeable.

The lens also supports different stabilisation modes, including Mode 2 for dynamic panning, making it useful for subjects such as motorsports and other fast-moving action. When paired with compatible Sony cameras featuring in-body stabilisation, additional stabilisation benefits are available.

Excellent Close-Focusing Capability

Although designed primarily as a super-telephoto lens, the Sony 100-400mm GM also offers impressive close-focusing performance. Its minimum focus distance is approximately 0.98 metres, with a maximum magnification ratio of 0.35x.

This allows photographers to move from distant wildlife or sports subjects to relatively close subjects without immediately needing another lens.

Designed for Outdoor Photography

Professional telephoto photography often takes place in challenging environments. The FE 100-400mm GM features a dust- and moisture-resistant design, adding confidence when working outdoors.

Its magnesium-alloy components and carefully designed construction also help balance durability with portability. At approximately 1,395g without the tripod mount, it offers substantial telephoto reach while remaining manageable for a professional-class 100-400mm lens.

Adjustable Zoom Torque and Professional Controls

The lens features a zoom smoothness adjuster, allowing photographers to control the resistance of the zoom ring. This is useful when switching between rapid framing adjustments and slower, more deliberate zoom movements.

A removable tripod mount is also included, allowing photographers to move efficiently between tripod-supported and handheld shooting.

Compatible with Sony Teleconverters

For photographers who need even greater reach, the SEL100400GM is compatible with Sony’s 1.4x and 2.0x teleconverters. With compatible teleconverters, the lens can achieve substantially greater effective focal lengths for specialist wildlife and distant-subject photography.

Ideal for Wildlife, Sports and Action Photography

The Sony FE 100-400mm F4.5-5.6 GM OSS Lens is an excellent choice for photographers who need long reach without sacrificing image quality. Wildlife photographers can use the extended focal length to photograph animals from a respectful distance, while sports photographers can frame athletes and action from the sidelines or spectator areas.

It is also suitable for bird photography, motorsports, outdoor events, travel photography, nature photography and professional photojournalism.
