G Master super-telephoto zoom

This top-performance G Master zoom lens covers a broad 100mm to 400mm focal length range that is ideal for sports, wildlife, and other subjects that require a long reach. It offers image quality and AF performance that will support professional fieldwork, tracking and capturing even fast-moving subjects with outstanding resolution and clarity.

Fast, tenacious autofocus

An optimal combination of double linear motor and DDSSM (Direct Drive SSM) drive systems is the first of its kind. It also implements precision sensors that provide real-time feedback for extremely high positioning accuracy, allowing the body’s AF system to perform at its best.

High resolution at any focal length

A precision optical design ensures consistently high corner-to-corner resolution at any focusing distance throughout the lens’s zoom range. The SEL100400GM not only delivers stunning images of distant subjects at super-telephoto focal lengths, it offers equally high performance when shooting nearby subjects as well.

Natural rendering and colour

Two ED (Extra-low Dispersion) glass elements and one Super ED glass element strategically deployed in an advanced optical design effectively suppress axial chromatic aberration that is often a cause of resolution falloff in telephoto lenses. The result is exceptionally clear, well-defined images.

Clarity and contrast in any light

Sony’s Nano AR Coating suppresses spurious reflections that can cause flare and ghosting in backlit and other challenging lighting situations, for consistently high contrast and clarity. Reduced flare, particularly when shooting in bright outdoor conditions, means greater framing and composing flexibility.

Compact, lightweight, and mobile

Magnesium alloy components and other refinements contribute to high durability as well as the class-leading size and weight reductions that not only mean greater mobility but improved manageability with lightweight bodies for easier, more stable handheld shooting.

Zoom torque adjustment

This is the first α lens to include a zoom smoothness adjuster that provides mechanical control of zoom ring torque. Set a lower torque for fast zooming, or increase torque when slow, stable zooming is required. Fine adjustment allows the feel of the lens to be matched to individual user needs.

Clear, blur-free images without a tripod

Built-in Optical SteadyShot image stabilization makes it easier to capture blur-free images, particularly when shooting sports or other subjects that require fast stabilization response. Mode 2 stabilization facilitates dynamic panned shots. 5-axis stabilization becomes available when used with α series bodies that feature in-body stabilization.

Outstanding shooting versatility

Floating focus and high positioning precision have made it possible to achieve a minimum focus distance of just 0.98 meters (3.22ft.) with up to 0.35x magnification. You have a versatile 100mm to 100mm super-telephoto zoom range, plus outstanding close-up performance at 100mm

Removable tripod mount

A removable tripod mount allows quick attachment to or removal from a tripod so the user can easily switch between tripod and handheld shooting. The mount can also be removed for convenient transport and storage. A lock mechanism prevents accidental removal.

If you want to use a Sony mirrorless camera for fast-moving sports and action – not just the Alpha 9, but also Alpha 7 series or Alpha 6000 series bodies – then the Sony FE 100-400mm f/4.5-5.6 GM OSS is a great choice.

Amateur Photographer

The Sony FE 100-400mm f/4.5-5.6 GM OSS is an optically stabilised long-telephoto zoom, designed to work with the firm’s full-frame E-mount mirrorless cameras. It costs £2500.

Photography BLOG

It came as no huge surprise to see Sony launching a long telephoto lens at the same time as the A9. When you use the two together, it becomes an ideal combination for typical sports, action and wildlife photography.

Sony FE 100-400mm f/4.5-5.6 GM OSS, Verdict:


This lens will be of particular interest to professional sports and wildlife photographers who use Sony’s mirrorless, full-frame cameras. Its size and weight are well-matched to the larger camera bodies, whereas it would be difficult to balance on a smaller and lighter, cropped-sensor body.

PC Magazine

The FE 100-400mm F4.5-5.6 GM OSS fills a telephoto gap in Sony's premium lens lineup, packing crisp optics, fast autofocus, and strong image stabilization into a compact, lightweight telezoom.

Camera Labs

The Sony FE 100-400mm f4.5-5.6 G Master is a telephoto zoom for its e-mount mirrorless cameras, and corrected for use on full-frame bodies. Announced alongside the professional Alpha A9 body, it delivers the longest reach of Sony's native e-mount lenses to date.

Photography Life

When the Sony FE 100-400mm f/4.5-5.6 GM lens was announced alongside the Sony Alpha 9 camera body, it created quite a stir within the Sony user base and thankfully the lens doesn’t disappoint. After testing it, I can say that I have yet to be disappointed by the performance of this lens.

The Digital Picture

Sorry for the delay in this review – I was having a little too much fun using the lens. And, reviewing thousands of images takes time. But, those images and the in-the-field use have given me strong insight into what this lens is capable of.

This is a quality lens giving pin sharp images throughout the zoom range. It is also excellent to use as a macro lens, and also works well with the 1.4 converter. It isn't the lightest lens but I have no problem carrying it all day on a black rapid strap.

I debated a long time whether I should get the Sony 100-400mm Gm over the cheaper options because of the price. I took the chance and bought it , wow the sharpness is the best . Really pleased with purchase and no regrets . Very expensive but worth it .


I have recently moved from A mount to E mount and required a telephoto zoom lens, as I like landscape, sports and moving objects like birds. So I chose this lens as it it had everthng that I required. It is just a fantastic lens with great zoom capability

I have only had this lens for two days, so not fully tested yet, but so far the performance has exceeded my expectations. Bought primarily for wildlife and some occasional sports photography, in combination with the new Sony A7 III.


I bought this lens to take on a wildlife trip to Norway in January. I have the 100-400 but needed a little extra distance and did not want a ‘trombone’ mechanism to zoom. The lens was easy to transport and was no problem with my carry on back pack with airlines.


I have owned and used the Sony 24mm, 24-105 and 70-200 lenses. I also have the 24-70 2.8. Despite other lenses being more compact, the Sony 100-400 GM is on my a7Riii all the time. I only switch when I want to photography something specific.

Used this lens for bird and nature photography, as well as some action shots using both stabalization modes with great sharp results...


Excellent lens purchased to accompany my A9 camera. Having already used the A mount version on a Sony A77 I was aware of the versatility of this lens for wildlife photography. Foreign trips with bulky 500 mm prime lenses are a thing of the past with no more bulky luggage and packing dilemmas .


This lens is wonderfully well-designed and built and relatively small and light. It produces outstanding images from an A7R4 at 100mm from wide open. At 400mm it can produce very sharp images in evenly lit scenes.

Thought long about getting this lens as i have the 70-200 which is excellent but just short of reach for some uses. I was very surprised how good the 100 -400GM lens is. Autofocus is very fast, shake compensation is effective and the results are pin sharp. I have equivalent lenses for my other system cameras and all round, none are as good as this lens. If you think you need this lens you will not regret buying it.

The 100-400 is a a superb quality built lens, vert versatile, close focusing for a telephoto lens, it gives nice bokeh.
