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.


Features:

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 descriptive performance at all zoom and focus ranges:
- The latest optical design, which employs luxurious glass materials including 6 FLD and 2 SLD elements of special low-dispersion glass, delivers high resolving power throughout the entire zoom range. Three aspherical lenses are used, as they are now indispensable for superior optical performance and streamlined lens construction. The exceptionally high precision of the aspherical lenses, which take advantage of the technical capabilities of SIGMA’s only production facility, the Aizu factory, further improves optical performance. The incorporated floating focus is advantageous in improving short-range performance, ensuring a stable, high-level image quality throughout the entire range from the minimum focusing distance to infinity.

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.

Designed to minimize focus breathing:
- The lens has been designed to suppress focus breathing. The change in angle of view due to focus shift is minimized, creating a natural-looking focus shift when recording video.

Designed to minimize flare and ghosting:
- Flare and ghosting, which reduce image quality, are addressed under all conditions of incident light based on the most advanced simulation technology. High backlight resistance enables clear and sharp images under any lighting conditions.

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.

High quality and durability despite its small size and lightweight:
- The latest optical and mechanical design streamlines the lens configuration and internal structure, resulting in a significantly smaller and lighter body than the previous SIGMA 70-200mm F2.8 DG OS HSM | Sports model. The body, including the hood, features a “multi-material structure” that optimally arranges materials such as magnesium, CFRP*1, and TSC*2. Even with enhanced mobility, the lens features SIGMA’s renowned excellent build quality, including high durability, reliable rigidity, and various control rings and switches that have been carefully designed to feel good.

Adoption of inner zoom mechanism:
- The zoom mechanism employs an inner zoom. Since the total length of the lens does not change with zoom operation, it is easy to handle when shooting hand-held, highly stable when installed on a gimbal, and resistant to dust and water droplets.

Weatherability of Sports line:
- The mount connection, manual focus ring, zoom ring, switches, switch panel and exterior connection are all dust and splash resistant* to prevent dust and dirt from entering the lens. Further, the front element of the lens features a water and oil repellent coating to facilitate maintenance when water droplets or dust adhere to the lens.

A wealth of functions to assist professional photographers:
- In addition to an aperture ring, a magnesium tripod mount, and various switches, the highly mobile lens has a wealth of functions available, enabling a more comfortable and versatile shooting experience for users.

Equipped with an aperture ring:
- This is the first SIGMA zoom lens for still photography to be equipped with an aperture ring. It is also equipped with an aperture ring click switch and an aperture ring lock switch, allowing for aperture operation suited to the shooting application.

Newly developed tripod socket:
- The lens body incorporates an Arca-Swiss compatible magnesium alloy tripod socket. The detachable leg is newly designed for the SIGMA 70-200mm F2.8 DG DN OS | Sports in order to achieve a compact and lightweight design.

Customizable functions:
- Equipped with a Focus Limiter switch, the lens enables users to limit the focus driving range during AF when necessary, allowing quick and precise focusing. Further, the lens features three AFL buttons ready to be assigned to preferred functions using the camera. The AFL buttons are easy to operate regardless of how the camera is oriented or which settings are used. For the L-Mount version, the SIGMA USB DOCK UD-11 can be used to set OS operation or focus limiter range for the Custom Mode switch.

Tele Converter for L-Mount (1.4x / 2.0x):
- The L-Mount version of the lens is compatible with the SIGMA TELE CONVERTER TC-1411 (1.4x) and TC-2011 (2.0x). Using a tele converter, the focal length can be multiplied by 1.4x and even 2x, for AF-enabled shooting at ultra-telephoto focal lengths of up to 400mm.

Cover-type lens hood included:
- A lightweight, high-strength, exclusive cover-type lens hood made of CFRP* is included. In addition to its slim design that does not impair the mobility of the lens, the tip of the hood is rubberized to protect the lens from abrasion and scratches caused by placing the lens upside down.
