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 linear motor HLA

A linear motor HLA (High-response Linear Actuator) is used for the actuator, which is characterized by its high driving accuracy owing to the advanced electronic control, as well as its quietness. The HLA enables fast and accurate autofocus even in ultra-telephoto photography, such as sports and bird, where extremely precise focusing is required.

OS2 algorithm in optical stabilizer function

The latest OS2 optical stabilization algorithm provides an outstanding image stabilization effect of 5.0 stops*. 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. * Based on CIPA guidelines (Measured at 500mm with a 35mm full-frame image sensor)

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. *1 CFRP (carbon fiber reinforced plastic), a light but strong material used in the interior and exterior fittings of aircraft, among many other applications. *2 TSC (Thermally Stable Composite) is a type of polycarbonate with a thermal expansion rate similar to that of aluminum. It has high affinity to metal parts which contributes to high quality product manufacturing

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 specifications

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.

*The structure is designed to be dust and splash resistant, but not waterproof. Be careful not to bring the lens in contact with a large amount of water. Water inside the lens may cause major damage and even render the lens unrepairable.

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

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

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.

*CFRP (carbon fiber reinforced plastic), a light but strong material used in the interior and exterior fittings of aircraft, among many other applications.
