Sigma 50-120mm f/2.8 DC OS Contemporary Fujifilm X Lens

The Sigma 50-120mm f/2.8 DC OS Contemporary is a versatile, high-performance telephoto zoom lens designed for APS-C mirrorless cameras, combining a constant f/2.8 maximum aperture with a compact and lightweight Contemporary-series design. Covering a useful short-telephoto to telephoto range, this lens is well suited to portrait photography, wildlife, sports, events, travel and everyday shooting where subject separation and low-light performance are important.

With a bright constant f/2.8 aperture throughout the 50-120mm zoom range, the Sigma 50-120mm f/2.8 DC OS Contemporary makes it possible to maintain consistent exposure settings while zooming and provides greater control over depth of field. The telephoto range is particularly useful for isolating subjects against soft backgrounds, making this an excellent choice for portraits, outdoor photography and action.

Advanced Optical Construction

Sigma has equipped the 50-120mm f/2.8 DC OS Contemporary with a sophisticated optical design incorporating one FLD glass element, three SLD glass elements and four aspherical elements. These specialised elements are designed to help control optical aberrations while maintaining high image quality across the zoom range.

The lens provides a 31.7° to 13.5° angle of view on Sony E-mount and Fujifilm X-mount versions, while the Canon RF-mount version offers a 30° to 12.8° angle of view.

Constant f/2.8 Aperture

The constant f/2.8 maximum aperture is one of the key advantages of the Sigma 50-120mm Contemporary. It provides a bright aperture across the entire zoom range, making the lens particularly useful for portraits, events, indoor photography and other situations where available light may be limited.

An 11-blade rounded diaphragm helps produce smooth and attractive out-of-focus areas, making it easier to achieve pleasing background separation and natural-looking bokeh.

Close-Focusing Telephoto Zoom

Despite its telephoto reach, the Sigma 50-120mm f/2.8 DC OS Contemporary offers impressive close-focusing capabilities. Minimum focusing distance ranges from just 23cm at the wide end to 55cm at the telephoto end, with maximum magnification ratios of 1:3 at 50mm and 1:4.7 at 120mm.

This makes the lens useful not only for portraits and distant subjects, but also for close-up details, flowers, products and creative telephoto photography.

Compact Contemporary Design

The Sigma 50-120mm f/2.8 DC OS Contemporary has been designed to provide strong telephoto performance without the size and weight associated with many larger professional zoom lenses. The Sony E-mount and Fujifilm X-mount versions weigh just 390g, making this a highly portable option for photographers who want a bright telephoto zoom without a bulky setup.

A 55mm filter thread provides compatibility with a wide range of readily available circular filters.
