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. But 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.

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.

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.

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.

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.

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.
