Compromisloze optische prestaties in een uitzonderlijk compacte behuizing. Dé lichtsterke telezoom voor APS-C-camera’s
De Sigma 50-120mm F2.8 DC OS | Contemporary is een lichtsterke telezoomlens voor APS-C-camera’s met een uitzonderlijk compact en lichtgewicht ontwerp. Dankzij het constante diafragma van F2.8 bestrijkt de lens een telebereik dat overeenkomt met circa 75 tot 180mm in full-frame termen. Geavanceerde prestaties gaan hand in hand met de draagbaarheid en mobiliteit die van een APS-C-lens worden verwacht, verpakt in een uiterst compacte behuizing van slechts 99 mm lang en een gewicht van slechts 390 gram*.
De fraaie achtergrondonscherpte en het natuurlijke compressie-effect die kenmerkend zijn voor een telelens maken deze lens geschikt voor uiteenlopende toepassingen, van portretfotografie tot evenementen en buitenopnames. Samen met de reeds verkrijgbare Sigma 10-18mm F2.8 DC DN | Contemporary en Sigma 18-50mm F2.8 DC DN | Contemporary vormt deze lens een complete zoomserie met een constant F2.8-diafragma, die het volledige bereik van ultragroothoek tot tele bestrijkt. Daarmee zet Sigma een nieuwe standaard voor APS-C-zoomlenzen met hoge beeldkwaliteit.

Easier to carry, with nothing given up: a new standard for APS-C telephoto zooms
A highly versatile zoom range of approximately 75-180mm in 35mm equivalent terms, a constant F2.8 aperture, uncompromising optical performance and full-fledged shooting features are all condensed into a compact body just 99mm long and weighing a mere 390g*1. It meets every high portability and mobility requirement of an APS-C lens, while raising the class’ standard for both performance and functionality, making it a definitive APS-C zoom lens.
*1 The figures are for Sony E-mount.
A high-performance constant F2.8 zoom series, from wide-angle to telephoto
With the Sigma 50-120mm F2.8 DC OS | Contemporary joining the Sigma 10-18mm F2.8 DC DN | Contemporary and Sigma 18-50mm F2.8 DC DN | Contemporary already on the market, the constant F2.8 zoom series is now complete, covering everything from ultra-wide-angle to telephoto. All three lenses together weigh less than 1kg, making it possible to put together a system that combines high performance with genuine mobility.
Lavish optical construction
An optical construction that combines one FLD glass element, three SLD glass elements and four aspherical elements in exactly the right arrangement achieves both high optical performance and compact dimensions. Throughout the zoom range, from the center of the frame to the edges, various optical aberrations are corrected to achieve exceptionally high contrast.
Rendering that only a telephoto lens can deliver
The large bokeh and compression effect of a telephoto lens equivalent to approximately 180mm in 35mm terms enable expression that ranges from portraiture that makes the subject stand out to flat product photography where perspective is kept in check.
Designed to minimize focus breathing
The optical design minimizes focus breathing. Because shifts in the angle of view during focusing are suppressed, the lens supports natural video expression with little change in composition.
Features that assist comfortable shooting
In addition to high-speed AF driven by an HLA (High-response Linear Actuator) linear motor, the OS2 image stabilization algorithm delivers 6.5 stops of optical stabilization at the wide end and 4.5 stops*2 at the telephoto end. Everything a telephoto zoom needs for demanding shooting conditions is brought together here in optimal balance.
*2 Based on CIPA guidelines. (Measured at a focal length of 50mm and 120mm using an APS-C mirrorless camera)
An intuitive, easy-to-understand control layout
Switches such as the focus mode switch and the OS switch have been removed, giving the lens a minimal, easy-to-understand interface that stays intuitive to operate despite its high functionality.
Dust- and splash-resistant structure*3 and water- and oil-repellent coating
In addition to a dust- and splash-resistant structure, the frontmost surface of the lens has a water- and oil-repellent coating, allowing photographers to shoot without concern even in difficult outdoor environments.
*3 The product is designed to be dust- and splash-resistant but is not waterproof. When using the lens near water, etc., take care not to allow large amounts of water to splash on it. If water gets inside the lens, it may cause a major malfunction.

MTF CHART
There are two types of MTF chart. One considers the diffraction quality of light, which is called "Diffraction MTF", and the other, "Geometrical MTF" does not.
The quality of light appears in the diffracted light, and becomes more distinct as the F value gets bigger, resulting in lower image quality. Also, diffracted light exists at every aperture, which is why Sigma has been releasing Diffraction MTF data from the beginning since it is very close to the actual image data.
The advantage of using "Geometric MTF" data is that it is easy to measure and calculate since it does not consider the diffraction quality of light, yet it tends to show higher values in the graph than actual images.
The readings at 10 lines per millimeter measure the lens's contrast ability ( red lines), repeating fine parallel lines spaced at 30 lines per millimeter measure the lens's sharpness ability (green lines), when the aperture is wide open.
Fine repeating line sets are created parallel to a diagonal line running from corner to corner of the frame, are called Sagittal lines (S) and sets of repeating lines vertical to these lines are drawn, called Moridional (M) line sets.
*The MTF chart gives the result at the wide-open aperture.

HLA (High-response Linear Actuator)
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.
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.
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.
