Sigma AF 100-400mm f/5-6.3 DG DN OS Contemporary Fujifilm X mount

An ultra-telephoto zoom Lens with Optical Stabilizer (OS) has several advantages.
The OS allows the photographer to shoot in almost any situation. The narrow angle of view of a telescope allows the perspective to be dramatically compressed and the background to be flexible. This allows the photographer to create the impression of a subject popping out of the frame, with the focused area impressively sharp and clear.

Ultra-telephoto Lenses have had some typical drawbacks, however.
As the suggestion of "telephoto giant" indicates, they tended to be large and heavy. It was therefore cumbersome to carry them. With the goal of creating an ultra-telephoto Lens that is much more practical, we incorporated our latest technologies into the SIGMA 100-400mm F5-6.3 DG OS HSM | Contemporary.

With its outstanding combination of optical performance and compactness, this is an ultra-telephoto Lens that is wonderful to carry and use. While retaining the robust functionality and exceptional image quality of an ultra-telephoto zoom Lens, we have created an amazingly compact body for a 400mm optic.

The SIGMA 100-400mm F5-6.3 DG OS HSM | Contemporary offers the compact size, light weight and price/performance ratio of a 70-300mm Lens, yet delivers the performance of a 400mm telephoto lens. This approach thus opens up an enticing new choice in ultra-telephoto lenses for photographers. With a combination of stunning image quality and superior functionality, the Lens meets the needs of professionals and amateurs alike.

Since its release, the SIGMA 150-600mm F5-6.3 DG OS HSM | Contemporary has won over photographers with its strong fundamental performance and exceptional image quality. The SIGMA 100-400mm F5-6.3 DG OS HSM | Contemporary retains that performance in a compact 400mm ultra-telephoto zoom Lens, with a filter diameter of just 67mm and weighing just 1,160g.

However, it also brings the full range of features and functions expected of an ultra-telephoto zoom: optical stabilizer (OS), Hyper-Sonic Motor (HSM) with updated algorithm for fast autofocus, focus range limiter, and more. What's more, these uncompromising features are customizable to personal preferences with the optional SIGMA USB Dock.

Compact body without compromising image quality
In developing this Lens, we wanted to push the envelope when it came to compactness and image quality. Four SLD (Special Low Dispersion) glass elements and optimized power distribution help reduce optical aberrations to a minimum. Even more, by taking special care in minimizing lateral chromatic aberration that cannot be corrected via iris control, we ensure excellent image quality throughout the zoom range.

Additional sliding zoom functionality
For quick control of the image angle, the zoom ring features sliding zoom functionality in addition to the standard rotating mechanism. The exclusive lens hood is also designed to support zooming via the slide-zoom mechanism and the overall mobility of the Lens. By allowing the angle of view to be adjusted instantly, this Lens gives photographers an even better chance of being able to take that decisive photo.

Telephoto and macro functionality
With a minimum shooting distance of 160 cm and a maximum magnification of 1:3.8, this Lens can be used to shoot from a distance or at close range.

Dust and splash-proof mount
Since the port of the Lens is particularly susceptible to dust and other foreign objects, the rubber seal ensures that you can be unconcerned.

New optical stabilizer (OS) with special algorithm
With a newly developed gyroscopic sensor and a new special algorithm, this OS delivers reliable stabilization. An accelerometer sensor detects camera movements in any direction - horizontal, vertical and diagonal. This technology enables the OS to stabilize the image very effectively, regardless of whether the camera is held in portrait or landscape orientation.

Includes Nikon's electromagnetic iris mechanism
In the Nikon version, the Lens features Nikon's Electromagnetic Iris Mechanism and is thus able to process signals from the camera body. This feature provides precise iris control and stable performance during automatic exposure (AE) in continuous shooting mode.

(Note: Functionality may be limited on some camera bodies)

Lens features:
DG
DG Lenses - SIGMA's DG Lenses are designed for demanding use on digital cameras with sensors up to 24x36mm (colloquially known as full-frame). The use of state-of-the-art coating processes successfully eliminates ghosting caused by reflections on the sensor surface, while achieving balanced color and superior optical performance.
Since these Lenses also illuminate the analog film format 24x36mm, their use is also possible on some suitable analog cameras, although we ask you to consult us on a case-by-case basis.

HSM
HSM Ultrasonic Motor (Hyper Sonic Motor) - HSM Lenses use a motor that is driven by ultrasonic waves. This technology offers you a very fast, exact and almost noiseless way of automatic focusing. Two different types of HSM ultrasonic drive are used in our Lenses. The first is the HSM ring motor, which is mainly installed in the high-quality EX Lenses. This HSM drive allows you to manually intervene in the AF operation at any time. On the other hand, an HSM micromotor is mainly used in compact Lenses, the so-called all-round zoom lenses. Here, manual intervention in the AF operation is not possible.

OS
Optical stabilizer (OS) - Sensors in the Lens detect camera movements that can lead to blur in the image, and in interaction with a movably suspended lens element, these movements are compensated for. Consequently, your photographic capabilities are increased to a significant degree when shooting freehand. Stabilized Lenses allow you to shoot handheld without shake for 3 - 4 exposure stops longer than usual. On camera models that are already equipped with a stabilizer, you have the choice of using the camera's stabilizer or the Lens's stabilizer. Stabilizers in the Lens, however, always have the advantage that they also provide you with a stabilized viewfinder image. This means that nothing stands in the way of an accurate assessment of the image and precise use of the focus.

IF
Internal focusing (IF) - With internally focused Lenses, only one or more lens groups are moved inside the Lens for the purpose of focusing. As with rear-focus lenses, this results in many advantages: Internal focusing provides faster and quieter focusing. With IF lenses, the build length of the Lens remains constant during focusing and the front lens does not rotate, allowing you to conveniently use polarizing filters and a tulip-shaped lens hood. Since the overall length of the Lens remains constant during focusing, there is no noticeable weight shift during focusing with this system. As a result, the Lens is well balanced at all times.
