The Sigma 100-400mm 5-6.3 DG HSM OS Contemporary is a telephoto zoom that brings a new level of portability and quality to the super telephoto market. Touting Sigma’s Optical Stabilizer (OS), the Sigma 100-400mm f/5-6.3 Contemporary is highly compact and lightweight compared to similar products on the market. A push/pull zooming function and a new Hyper Sonic Motor (HSM) allow for a more responsive approach to photography while a 1:3.8 macro feature can be utilized from up close or from a further distance. The Optical Stabilizer also benefits handheld shooting by minimizing the appearance of camera shake for sharper imagery. The brass bayonet mount also offers rigidity and mounting precision.

C - Contemporary Lens

This lens is part of the Contemporary category of Sigma's Global Vision. Sigma's Contemporary lenses combine modern techniques and materials in order to deliver a concept that combines a streamlined, lightweight construction with best-in-class optical quality and performance. This compact lens is one you trust for a variety of everyday applications.

DG - DG for Digital

Sigma's DG lenses are specifically designed to deliver the ultimate level of performance on full-frame digital SLRs. Sigma DGs also maximize the abilities of 35mm SLR cameras and APS-C size DSLRs. Thanks to a complete and comprehensive approach to the correction of chromatic aberrations, you will experience incredible image clarity and smoothness. Specific attention was paid to helping eliminate color fringing often caused by lateral chromatic aberration, a problem that is magnified at high resolution in digital photography.

Super Multi-Layer Coating

DG lenses provide exceptionally high contrast along with subtle gradations in tone and color. Super Multi-Layer Coating, along with Sigma's optimized optical design work to reduce reflections between the image sensor and the lens surfaces. The large image circles of DG lenses mean there will always be enough peripheral illumination to avoid vignetting.

HSM - Quiet and Fast Autofocusing

HSM lenses employ a motor powered by ultrasonic waves that produce a quiet, yet high-speed AutoFocus. You can enjoy high performance with low noise in a variety of shooting situations.

Uncompromising Image Quality

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

Push/Pull Zoom Mechanism

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.

Sigma USB Dock for Canon Lenses

The Sigma USB dock works in conjunction with Sigma Optimization Pro software in order to connect a photographer's lens to their personal computer to update firmware, calibrate the lens and other customizations such as the focus parameter. The dock is only compatible with the Sigma Art, Contemporary, and Sports line lenses featuring a Canon EF lens mount. For the Sports category, changes can be made to: Autofocus speed, focus limiters, manual focus override and optical stabilization functionality. Updating the firmware can be done via the internet. Sigma Photo Pro is available for Mac and PC computers.
