CONTEMPORARY
50–120mm F2.8 DC OS

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^*. 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 telephoto zoom lens.

* The figures are for Sony E-mount.

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.

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.

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.

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.

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^* at the telephoto end. Everything a telephoto zoom needs for demanding shooting conditions is brought together here in optimal balance.

* Based on CIPA guidelines. (Measured at a focal length of 50mm and 120mm using an APS-C mirrorless camera)

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.

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.

* 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.
