Performance, reliability, and mobility at its highest level.

The large F2.8 aperture provides stable and high descriptive performance at all zoom and focus ranges. The high-speed AF with a dual HLA (High-response Linear Actuator) based on a floating focus structure, and the Optical Stabilizer function with the OS2 algorithm with up to 7.5 stops of correction effect*, ensure that users can take the right shot when there is no room for error. The highly mobile lens with high durability, rigidity, and texture is equipped with a wealth of functions to assist comfortable shooting, including an inner zoom mechanism for easy handling, as well as an aperture ring and switches with various customization functions. The flagship SIGMA 70-200mm F2.8 DG DN OS | Sports, combined with the best of SIGMA's latest technologies to meet the high-level demands of professionals, has finally arrived.

High-speed AF and optical stabilizer function that maximize superior optical performance
The SIGMA 70-200mm F2.8 DG DN OS | Sports, developed with professional use in mind, offers not only high optical performance, but also high-speed AF with a dual HLA (High-response Linear Actuator) and an optical stabilizer function with up to 7.5 stops. The Sports line lenses offer high optical performance, and all functions are based on state-of-the-art technology.

High-speed AF with a dual HLA
The SIGMA 70-200mm F2.8 DG DN OS | Sports with floating focus has a structure in which the two focus groups move in opposite directions, thereby reducing the amount of focus lens movement by about half. In addition, the use of an HLA (High-response Linear Actuator) motor in each of the two focus groups enables high-speed autofocusing. In addition to being fast and accurate, the lens also employs a control program that is designed to be quiet, so users can shoot movies comfortably without worrying about noise.

OS2 algorithm in optical stabilizer function
The latest OS2 optical stabilization algorithm provides an extremely high image stabilization effect of 7.5 stops at the wide end and 5.5 stops at the telephoto end. The lens is equipped with two OS modes: Mode 1 is suitable for general shooting, and Mode 2 is ideal for panning shots of motorsports and other sports. In Mode 2, SIGMA’s Intelligent OS, an algorithm specially designed for panning shots, enables effective image stabilization even when the camera is moved vertically or diagonally, irrespective of the horizontal and vertical orientation. This ensures that the subject’s movement can be captured without losing the panning shot effect.

Top-level build quality condensed into a highly mobile lens
SIGMA is committed to excellent build quality in all its lenses. Among them, the SIGMA 70-200mm F2.8 DG DN OS | Sports, which is part of the Sports line, offers not only high weather resistance performance for shooting in harsh environments, but also improved quality and durability through the use of cutting-edge materials in appropriate places based on a streamlined optical and mechanical design. At the same time, a high level of mobility is also realized, resulting in a professional equipment that can be used with confidence over the long term.

The full-frame SIGMA 16-28mm F2.8 DG DN | Contemporary combines exceptional optical quality, a bright F2.8 constant aperture and a robust and lightweight body, opening up new possibilities for L-Mount and Sony E-mount shooters who need professional results in a compact package.

With its excellent field curvature correction, the 16-28mm F2.8 DG DN | Contemporary is able to achieve exceptional edge-to-edge sharpness, which is essential for most wide-angle applications. It boasts five FLD elements and four aspherical lens elements to ensure optimal image quality with minimal aberrations. The lens has an inner zoom mechanism that keeps overall length consistent throughout the entire zoom range, helping it feel balanced in the hand. The inner zoom also means the lens’ center of gravity stays fairly constant, so it’sperfect for gimbal use. A front filter thread allows filters to be attached more easily.

The lens boasts an exceptionally compact form-factor, weighing in at just 450g and measuring just 100.6mm in length, which makes it a highly practical optic that is portable enough for everyday shooting. It’s especially appealing for landscape, wedding and travel photographers who need to carry their kit for long periods.Lightweight, versatile and extremely capable, SIGMA’s 16-28mm F2.8 DG DN | Contemporary offers photographers effortless freedom at the ultra-wide end.

A constant aperture of 2.8 through the zoom range makes this a highly versatile modern workhorse equipped for any shoot.

Best-in-class optical performance

The F2.8 Art zoom flagship zoom lens series is developed primarily to achieve superior optical performance.

As extra-low dispersion glass materials, six sheets of "F" low dispersion (FLD) glass and two sheets of special low dispersion (SLD) glass are lavishly employed while taking advantage of an optical design dedicated for mirrorless lenses. By employing three aspheric lenses, this zoom lens thoroughly subdues aberrations such as axial chromatic aberration or sagittal coma aberrations, which are difficult to correct in post-processing, tailors the resolution and achieves uniformity and superior optical performance from the center to the periphery throughout the zoom range.

In addition to Super Multi-Layer Coating, Nano Porous Coating* is employed. This lens is designed so as to be less affected by strong incident light such as flare.

The mirrorless camera-dedicated design successfully contributes to reduction in the lens size and weight.

• Designed especially for mirrorless
• Zoom lock switch
• Lens hood with a lock
• Dust- and splash-proof structure
• Compatible with the Lens Aberration Correction

^{* In the SIGMA's own proprietary coating technology, NPC (Nano Porous Coating), porous silica is employed for coating materials. A porous silica layer creates Nano-sized pores inside which air is contained. The pores of this size make it possible to reduce the refractive index significantly, even lower compared with the existing antireflection coatings, thereby drastically reducing reflected light causing flare and ghosting and achieving the high-contrast and clear image quality.}
