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

A compact body and top performance in one complete package

An ultra-telephoto lens with an optical stabiliser (OS) system has several advantages. The OS allows the photographer to take photographs in unstable circumstances. The narrow angle of view makes it possible to dramatically compress perspective and flexible handling of the background. The photographer can thereby make the subject appear to jump out of the image, with the area in focus impressively sharp and clear. Nevertheless, ultra-telephoto lenses have traditionally had some disadvantages as well. With the goal of creating an ultra-telephoto lens that is far more accessible, SIGMA incorporated all of its latest technologies into 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 a joy to carry and use. While keeping the robust functionality and exceptional image quality of an ultra-telephoto zoom lens intact, SIGMA has achieved amazingly compact packaging enclosing 400mm optics. Introducing the new and greatly enhanced ultra-telephoto zoom lens.

Key Features:

1. Top performance with the specification and functionality of a more expensive unit

Since its release, the SIGMA 150-600mm F5-6.3 DG OS HSM | Contemporary has won photographers over with its strong fundamental performance and exceptional image quality. The new lens retains all of this performance in a compact 400mm ultra-telephoto zoom package with a filter size of just ?67mm and weight of just 1,160g. Yet it also comes with the full range of features and functions expected of an ultra-telephoto zoom: optical stabilizer (OS), hypersonic motor (HSM) with updated algorithm for fast autofocus, focus limiter, and more. In addition, this uncompromising specification becomes customisable with the available SIGMA USB Dock accessory.

2. Compact packaging with uncompromising image quality

In designing this lens, SIGMA strived to push both compactness and image quality to the limit. Four SLD (Special Low Dispersion) glass lens elements and an optimised power distribution help minimise optical aberrations. Moreover, by taking special care to minimise transverse chromatic aberration, which cannot be corrected via aperture control, SIGMA has ensured outstanding image quality throughout the zoom range.

3. Push/pull zoom mechanism incorporated

For quick control of the angle of view, the zoom ring incorporates a push/pull mechanism in addition to the regular twist mechanism. The exclusive lens hood has also been designed to accommodate push/pull zooming and overall lens maneuverability. By making it possible to adjust the angle of view instantly, this lens gives photographers an even better chance of getting that crucial shot.

4. Telephoto plus macro functionality

With a minimum shooting distance of 160cm and a maximum magnification ratio of 1:3.8, this lens can shoot either from a distance or up close.

5. Other features

• Dust- and splash-proof mount 
  Since the area of the lens most vulnerable to dust and other foreign bodies is the mount, rubber sealing helps provide peace of mind.
• All-new optical stabiliser (OS) unit with exclusive algorithm 
  Featuring a newly developed gyroscopic sensor and a new and exclusive algorithm, the all-new OS unit provides a powerful stabilisation effect. An acceleration sensor detects camera shake in any direction—horizontal, vertical, or diagonal. This technology allows the OS to stabilise the image very effectively, regardless of whether the camera is being held in horizontal or vertical orientation.
• Nikon electromagnetic diaphragm mechanism included 
  The Nikon mount version of this lens includes an electromagnetic diaphragm mechanism that allows it to receive the appropriate signals from the camera body. This feature ensures precision diaphragm control and stable Auto Exposure (AE) performance during continuous shooting. Note: Functionality may be limited on some camera bodies.
