Sigma AF 100-400mm F5-6.3 DG DN OS Contemporary lens for Fujifilm X Mount 

The Sigma 100-400mm f/5-6.3 DG DN OS Contemporary, is lightweight, compact lens with a versatile telephoto range. This lens can be handheld, creating flexibility when travelling and adapting to different situations.

This lens is designed with super crisp, low dispersion glass elements which produce great colour clarity and accuracy throughout the zoom range.  The special coatings on the glass also help to suppress chromatic aberrations and colour fringing.

The lens operates beautifully with a stepping motor, delivering fast, near silent autofocus performance along with fine tuned manual focus control. Additionally, four stop-effective optical image stabilization helps to reduce the appearance of camera shake.  An optional TS-111 Tripod can be bought separately to add to a tripod for steady shooting.

Stellar results, anywhere, anytime

Optical performance and functionality that deliver professional-quality results, all packed into a lightweight and compact body, this versatile, ultra-telephoto zoom is the perfect option for both dedicated field photography and casual shooting. The lens is perfect for wildlife, action and portraits, and thanks to its short minimum focusing distance, which gives a magnification ratio of 1:4.1, it’s also ideal for capturing close-up subjects in stunning detail.

Updated optical design

The lens has a redesigned from the ground up for mirrorless cameras. Its optical design is very different from the DG HSM version of the lens. 22 elements in 16 groups include one FLD element and four SLD elements used for the effective correction of aberrations and distortions.

Outstanding optical quality

The SIGMA 100-400mm F5-6.3 DG DN OS boasts even better image quality than the brilliant DG version of the lens, with high-resolution image quality all the way to the edges, and superb optical performance across the zoom and focus range.

Advanced features for smooth and easy telephoto shooting.

Fast, smooth AF is enabled by a stepping motor optimised to the latest algorithm, and the lens has powerful image stabilisation (OS) of four stops* built in. When combined with a camera body with its own image stabilisation, the lens corrects for pitch and yaw axis rotations, providing even more compensation for camera shake. The stabilisation has two modes – one for general shooting and one for panning – and it’s possible to toggle between them quickly using a switch on the lens body.

The lens features an AFL button, to which the user may assign a range of different functions via the camera, and a focus limiter switch that allows the user to optimise the AF range depending on the subject distance.

Excellent build quality

The construction of the lens is designed to be both light and robust, with careful consideration given to utilising the right materials in the right place. Magnesium alloy, for example, which is very strong, is used around the tripod socket attachment, whereas for some other parts of the barrel, durable but light polycarbonate is used.

The lens features the dust- and splash-proof seal on the mount to stop contamination in difficult shooting environments such as on beaches and during rainfall. There’s also a water- and oil-repellent coating on the front most surface of the lens, which helps keep the from element clear of debris.
