Hoge-snelheid AF en optische stabilisatie voor superieure optische prestaties

De SIGMA 70-200mm F2.8 DG DN OS | Sports, ontwikkeld met professioneel gebruik in gedachten, biedt niet alleen hoge optische prestaties, maar ook snelle autofocus dankzij een dubbele HLA (High-response Linear Actuator) en een optische stabilisatiefunctie met tot wel 7,5 stops. De objectieven uit de Sports-lijn leveren uitstekende optische prestaties en alle functies zijn gebaseerd op de nieuwste technologie.

Hoge resolutieprestaties bij alle zoom- en scherpstelbereiken

Het nieuwste optische ontwerp, waarin hoogwaardige glaselementen zijn verwerkt, waaronder 6 FLD- en 2 SLD-elementen van speciaal laag-dispersieglas, zorgt voor een hoge resolutiekracht over het volledige zoombereik. Drie asferische lenselementen zijn essentieel geworden voor superieure optische prestaties en een efficiënte lensconstructie. De uitzonderlijk hoge precisie van de asferische lenzen, mogelijk gemaakt door de technische expertise van SIGMA's enige productiefaciliteit, de Aizu-fabriek, verbetert de optische prestaties verder. De zwevende scherpstelling verbetert de prestaties op korte afstand en garandeert een stabiele, hoogwaardige beeldkwaliteit van de minimale scherpstelafstand tot oneindig.

Snelle autofocus met een dubbele HLA

De SIGMA 70-200mm F2.8 DG DN OS | Sports beschikt over een zwevend scherpstelsysteem waarbij twee scherpstelgroepen in tegengestelde richtingen bewegen, wat de hoeveelheid beweging van de scherpstellens met ongeveer de helft vermindert. Daarnaast maakt het gebruik van een HLA-motor in beide scherpstelgroepen snelle en nauwkeurige autofocus mogelijk. Bovendien is de lens voorzien van een speciaal ontworpen besturingsprogramma dat fluisterstil werkt, zodat gebruikers zonder storend geluid video-opnamen kunnen maken.

OS2-algoritme in optische stabilisatiefunctie

Het nieuwste OS2 optische stabilisatie-algoritme zorgt voor een extreem hoge beeldstabilisatie van 7,5 stops bij de groothoekstand en 5,5 stops bij de tele-instelling*. De lens beschikt over twee OS-modi: Modus 1 is geschikt voor algemeen fotograferen, terwijl Modus 2 ideaal is voor panning-opnamen van motorsport en andere sportevenementen. In Modus 2 zorgt SIGMA's Intelligent OS, een algoritme speciaal ontworpen voor panning-opnamen, voor effectieve beeldstabilisatie, zelfs wanneer de camera verticaal of diagonaal wordt bewogen. Dit garandeert dat de beweging van het onderwerp wordt vastgelegd zonder het panning-effect te verliezen.

*Gebaseerd op CIPA-richtlijnen (gemeten bij 70mm en 200mm met een 35mm full-frame beeldsensor)

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

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.

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

OS (Optical Stabilizer) function

Sigma's original 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. Owing to the stabilized image in the viewfinder, it is possible to fine-tune composition and ensure accurate focusing.

OS2

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.

Inner Zoom

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.

Inner focus system

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

Stepping Motor

The lens is capable of smooth, quiet and high-speed AF made possible by a stepping motor, as well as supports Face/Eye Detection AF and video AF.

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).

Super Multi-Layer Coating

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 ef fective, assuring images of outstanding contrast.

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

Mounted with 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 locking system to prevent from unintended movement of the aperture ring during shooting.

Focus Mode Switch

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

AFL button

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

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.
