70-200mm F2.8 DG DN OS

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.

Top-level build quality condensed into a highly mobile lens

High quality and durability despite its small size and light weight

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

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

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.

* When turned ON at the position A, the iris ring is locked at A. When turned ON at a position other than A, it is locked within the range between the maximum to minimum apertures and will not engage at the position A.

Newly developed tripod socket

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.

* Only on compatible cameras. Available functions may vary depending on the camera used.

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.

Sigma's OS (Optical Stabilizer) function uses sensors inside the lens to detect any motion, then moves specific lens elements in order to effectively minimize blur caused by such movement.

OS2 is the newly developed optical stabilizer algorithm. Compared to the previous algorithm used by Sigma lenses, OS2 improves the effect of optical stabilization significantly.

To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.

The lens incorporates an inner zoom. With their unchanging barrel length, these lenses also enhance balance and stability for the photographer. Furthermore, since the front of the lens does not rotate, polarizing filters can be used with extra convenience.

Compatible with Lens Aberration Correction

Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.

*Function available on supported cameras only. Available corrections or auto correction functionality may vary depending on the camera model.
*On cameras where lens aberration correction is controlled with 'ON' or 'OFF' in the camera menu, please set all aberration correction functions to 'ON' (AUTO).

HLA is Sigma's proprietary linear motor. It drives the focus lens directly without going through gears or other mechanical parts, resulting in quiet, high-precision autofocusing.

Sigma's own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections with in the lens. All lenses in the current SIGMA range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, Sigma's Super Multi-Layer Coating is highly effective, assuring images of outstanding contrast.

Nano Porous Coating

NPC (Nano Porous Coating) incorporates porous silica as the coating material. The porous silica layer has nano-sized holes with air inside. Having holes of this size enables a large reduction in the refractive index, allowing the reflectance to be lowered more than conventional anti-reflective coatings. As a result, reflected light causing flares and ghosting is sharply reduced, achieving clear image quality.

Water and oil repellent coating

Incorporates a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.

Aperture ring

Aperture ring, designed to help users work intuitively.

Aperture ring click switch

Offers a de-click function for removing clicks by the aperture ring click switch, enabling seamless operations that are especially useful such as during video shooting.

Aperture ring lock switch

A ring lock system to prevent from unintended movement of the aperture ring during shooting.

The AFL button can be assigned with various functions widens the range of operations available on the lens.

Focus Mode Switch

Using this switch, it is possible to switch the focus mode between AF and MF.

Focus Limiter

Offers customization for the driving range of autofocus. It makes it possible to limit the drive range from a specific distance to a long distance or a short distance.

Linear focus / Non-linear focus (for L-Mount only)

A focus movement method of interchangeable lenses for mirrorless cameras in relation to the rotational angle of the focus ring during manual focusing. With "non-linear focus" the amount of focal point movement varies depending on the focus ring rotational speed. With linear focus, if the focus ring rotational angle is the same, the amount of focal point movement remains the same regardless of the focus ring rotational speed.

Dust and Splash Resistant Structure

This lens features a highly effective dust and splash resistant structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection.

*Although this construction allows the lens to be used in light rain, it is not the same as being waterproof, so please prevent large amounts of water from splashing on the lens. It is often impractical to repair the internal mechanism, lens elements and electric components if they are damaged by water.
