Sharp super-telephoto zoom, tenacious AF
The first super-telephoto zoom in Sony's flagship G Master series covers a versatile 100 mm to 400 mm range. With extraordinary resolution and fast, precise autofocus, it lets you capture distant action with outstanding quality and immediacy. In addition to world-class image quality, this fine lens offers the mobility, reliability, and operability that professional applications demand.

G Master super-telephoto zoom
A 100 mm to 400 mm zoom range is ideal for sports, wildlife and similar subjects, with image quality and AF performance that support professional working needs.

Fast, tenacious autofocus
An optimal combination of double linear motor and DDSSM (Direct Drive SSM) drive systems achieves quick response, high accuracy and tenacious tracking.

High resolution and fast AF at any focal length
Precision G Master optics ensure consistently high corner-to-corner resolution at any focusing distance throughout the lens' zoom range.

Compact, lightweight and mobile
Innovative modular exterior construction and magnesium components reduce weight and size for improved portability and mobility.

Outstanding shooting versatility
A floating focus mechanism achieves a minimum focus distance of just 0.98 metres (3.22 ft.) so you can track and shoot subjects at any distance with one lens.

Features

G Master super-telephoto zoom
This top-performance G Master zoom lens covers a broad 100 mm to 400 mm 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
The 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.

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

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.

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.

Zoom torque adjustment
This is the first alpha 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.

Outstanding shooting versatility
Floating focus and high positioning precision have made it possible to achieve a minimum focus distance of just 0.98 m (3.22 ft) with up to 0.35x magnification. You will have a versatile 100-mm to 400-mm super-telephoto zoom range, plus outstanding close-up performance at 100 mm.

Clear, blur-free images without a tripod
Built-in Optical SteadyShot image stabilisation makes it easier to capture blur-free images, particularly when shooting sports or other subjects that require a fast stabilisation response. Mode 2 stabilisation facilitates dynamic panned shots. 5-axis stabilization becomes available when used with alpha series bodies that feature in-body stabilisation.

Customisable focus hold button
Conveniently located focus hold buttons provide focus hold control even during continuous AF operation. They can also be customised from a camera menu that allows them to be assigned to a variety of different functions.

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.

Teleconverters for extra reach
SEL100400GM is fully compatible with the high-performance SEL14TC and SEL20TC teleconverters for a 1.4x or 2x increase in focal length, respectively. That's a maximum focal length of 800 mm (1200 mm on an APS-C format body).

Fluorine coated front element
The lens's front element features a fluorine coating that helps to prevent dirt and fingerprints from sticking and makes it easier to wipe dirt and fingerprints away as they do become attached to the lens surface. This can be a significant advantage for outdoor shooting.

High reliability in harsh conditions
The overall design of this lens is dust and moisture resistant for extra protection and reliable operation in challenging environments. Shoot with confidence in light rain or windy conditions.

Pro lens hood features
An access window that can be opened or closed as required allows easy access for polarizing filter operation, and a hood lock switch prevents accidental detachment or rotation of the lens hood while shooting or moving around.
