Sigma 100-400mm f5-6.3 DG OS HSM Contemporary lens for Canon EOS

Ideal for photographers who need a high-performance long-telephoto zoom in a lightweight package, the 100-400mm is perfect for fast-action subjects such as sports, wildlife and motorsport.

Owing to its portable body that weighs in at less than 1.2kg, it’s also well-suited to a range of other genres, including telephoto landscapes and pet photography.

It’s even capable of macro-style close ups thanks to its maximum magnification ratio of 1:3.8.

• Aperture Range: f/5 to f/22
• Four SLD Elements
• Super Multi-Layer Coating
• Hyper Sonic Motor AF System
• OS Image Stabilization
• Rounded 9-Blade Diaphragm

Optically the 100-400mm delivers outstanding sharpness right across the zoom range, with four SLD elements and cutting-edge Super Multi-Layer Coating to keep chromatic aberration and flare to an absolute minimum.

The lens has Sigma’s intelligent two-mode Optical Stabilizer built in to help reduce camera shake when hand-holding in lower light. A range of other features including a focus limiter switch, custom modes, manual focus override and a dust- and splash-proof mount make the 100-400mm an extremely versatile long telephoto option that can be used in a wide range of shooting conditions.

High-performance optics

Despite weighing only 1,160g, the 100-400mm F5-6.3 DG OS HSM | C delivers outstanding optical quality even on very high-resolution sensors. Optical performance is maintained across the whole frame, meaning fine detail is rendered perfectly right into the corners.

The lens has an advanced optical design made up of 21 elements in 15 groups, including 4 SLD elements. These ensure razor-sharp results and help to eliminate chromatic aberration, flare, distortion and vignetting.

The lens has advanced optical coatings which reduce flare and ghosting when working in bright direct sunlight, creating high contrast images with rich colours and deep blacks.

A perfect option for longer landscapes

Owing to its portability and exceptional image quality the 100-400mm is a favourite with landscape photographers, allowing them to pick out small vignettes within the landscape and compress the perspective of a scene.

Lighting-fast AF

The lens has an HSM (Hyper Sonic Motor) focusing system that ensures fast, accurate and quiet AF. The updated algorithm enables smoother AF operation. This makes the lens ideal for fast-moving objects such as cars, planes and wildlife.

Compact and lightweight

As long telephoto lenses go, the 100-400mm is very light and compact at less than 19cm in length. This makes it ideal for anyone carry their kit over long distances, or anyone shooting hand-held for long periods. The lens is 770g lighter than SIGMA’s 150-600mm F5-6.3 DG OS HSM | C, although it doesn’t have as much reach or as many features, such as an included tripod foot.

Outstanding build quality

The exterior barrel of the 100-400mm is constructed using a polymer called Thermally Stable Composite (TSC). This has a similar thermal expansion rate to aluminium, meaning that the metal interior of the lens and the TSC exterior behave in the same way as temperatures change. TSC is also light and strong, and has a sleek finish for a premium look and feel.

The lens has an internal focus mechanism as well as Dual Action Zoom, meaning it’s possible to zoom in and out accurately using the zoom ring, or very quickly simply by pushing or pulling the end of the barrel. The zoom ring is rubberised for easier operation, and it can be locked at various positions using the Lock switch.

The durable brass mount is surrounded by a rubber seal to help keep out dust and moisture.

Professional feature-set

A range of controls on the lens include an AF/MF switch with manual focus override, an AFL button that can be customised (depending on the camera body) to a range of different functions, and a Custom Mode switch.

The lens also has a focus limiter so that the focusing range can be reduced for faster and more accurate operation. This is particularly useful when there are objects in the frame between the camera and the subject that the lens might attempt to focus on.

The in-built Optical Stabilizer has a mode for general shooting and one for panning – ideal for fast-moving birds and vehicles.

The lens has an HSM focus motor that delivers smooth, fast and accurate AF for both stills and video. It is fully compatible with all the latest AF camera technology.

Made in Japan

All Sigma cameras and lenses are designed, manufactured and assembled at their sole factory at Aizu in Japan. This domestic production model is unusual in today’s industry, with most imaging companies opting to outsource to other countries to reduce costs. But SIGMA believes that keeping virtually all manufacturing, processing and assembly in Aizu is essential for creating innovative, carefully thought-out and impeccably constructed products that meet the high standards demanded by professional photographers and film-makers around the world.
