Sigma AF 100-400mm f/5-6.3 DG DN OS Contemporary L-Mount

An ultra-telephoto zoom Lens with an optical stabilizer (OS) has several advantages.
The OS allows the photographer to shoot in almost any situation. Due to the narrow angle of view of a telephoto lens, the perspective can be dramatically compressed and the background can be flexibly designed. This allows the photographer to create the impression of a subject jumping out of the frame, with the focused area impressively sharp and clear.

However, ultra-telephoto lenses have also had some typical disadvantages.
As the suggestion "telephoto giant" indicates, they tended to be large and heavy. It was therefore cumbersome to carry them. With the aim of creating an ultra-telephoto lens that is much more practical, we have incorporated our latest technologies into the SIGMA 100-400 mm 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-tele zoom lens, we've 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 opens up a tantalizing new choice for photographers when it comes to ultra-telephoto Lens. 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 this performance in a compact 400mm ultra-telephoto zoom lens, with a filter diameter of just 67mm and a weight of 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, focusing range limiter and much more. What's more, these uncompromising features are customizable to personal preferences with the optional SIGMA USB dock.

Compact body without compromising on image quality
When developing this Lens, we wanted to push the limits in terms of compactness and image quality. Four SLD (Special Low Dispersion) glass elements and an optimized power distribution help to reduce optical aberrations to a minimum. What's more, by taking special care to minimize lateral chromatic aberration, which cannot be corrected via the aperture control, we guarantee outstanding image quality over the entire zoom range.

Additional sliding zoom functionality
For quick control of the image angle, the zoom ring has a sliding zoom functionality in addition to the standard rotating mechanism. The exclusive lens hood is also designed to support zooming via the sliding zoom mechanism and the general mobility of the Lens. By allowing the angle of view to be adjusted instantly, this lens gives the photographer an even better chance of taking the decisive shot.

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 take photos from a distance or at close range.

Dust and splash-proof mount
As the mount of the Lens is particularly susceptible to dust and other foreign bodies, the rubber seal ensures that you can be worry-free.

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

Includes Nikon's electromagnetic aperture mechanism
In the Nikon version, the Lens features the electromagnetic aperture mechanism and is therefore able to process the signals from the camera body. This feature ensures precise aperture control and stable performance with automatic exposure (AE) in continuous shooting mode.

(Note: functionality may be limited on some camera bodies.)

Connection change service possible: Enables use on a different camera

Lens features:
DG
DG Lens - SIGMA's DG lenses are designed for demanding use on digital cameras with sensors up to 24x36mm format (colloquially known as full-frame format). The use of state-of-the-art coating processes successfully eliminates ghost images caused by reflections on the sensor surface, while achieving a balanced color balance and outstanding optical performance.
As these lenses also illuminate the analog film format 24x36mm, their use on some suitable analog cameras is also possible, although we would ask you to contact us in individual cases.

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, precise and almost silent way of automatic focusing. Two different types of HSM ultrasonic drive are used in our lenses. One is the HSM ring motor, which is mainly used in the high-quality EX Lens. This HSM drive allows you to manually intervene in AF mode at any time. On the other hand, an HSM micromotor is primarily used in compact Lens, the so-called all-round zoom lenses. Manual intervention in AF mode is not possible here.

OS
Optical stabilizer (OS) - sensors in the Lens detect camera movements that can lead to blurring in the image and, in conjunction with a movably suspended lens element, these movements are compensated for. As a result, your photographic options for freehand shots are increased considerably. Stabilized Lens allow you to shoot handheld without blurring 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 that of the Lens. However, stabilizers in the Lens 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 Lens, this results in many advantages: Internal focusing ensures faster and quieter focusing. With IF lenses, the overall length of the lens remains constant during focusing and the front element does not rotate, which allows you to conveniently use polarizing filters and a tulip-shaped lens hood. As the overall length of the Lens remains constant during focusing, there is no noticeable weight shift when focusing with this system. As a result, the Lens is well balanced at all times.
