The Sigma 50-120mm f/2.8 DC OS Contemporary Lens (FUJIFILM X) delivers impressive telephoto versatility in an exceptionally compact and lightweight design for APS-C cameras. Combining a flexible zoom range with a bright, constant f/2.8 maximum aperture, this portable lens is ideal for portraits, travel photography, events, and capturing subjects at varying distances without sacrificing mobility.
Featuring a 50-120mm focal length range, the lens provides the flexibility to capture everything from detailed portraits to distant subjects. Its constant f/2.8 aperture maintains consistent exposure throughout the zoom range while offering greater control over depth of field and subject separation, making it particularly useful for creating images with beautifully isolated subjects.
A high-speed autofocus system delivers quick, responsive focusing performance, helping photographers capture spontaneous moments and moving subjects with confidence. Integrated Optical Stabilization (OS) helps minimize the effects of camera shake, supporting sharper handheld images when shooting at longer focal lengths or in challenging lighting conditions.
The optical design incorporates specialized glass elements engineered to control distortion, helping maintain image clarity and accurate subject rendering throughout the zoom range. This balance of optical performance and practical functionality makes the lens a versatile choice for both photography and video applications.
Despite its telephoto capabilities and bright aperture, the Sigma 50-120mm measures just 3.9" in length and weighs under one pound, making it exceptionally convenient for travel, handheld shooting, and everyday use. As part of Sigma's Contemporary series, it combines portability, optical performance, and reliable functionality in a compact package built for creators who need professional versatility without unnecessary bulk.
Responsive Autofocus
Easily focus on everything from static landscapes to playing children thanks to the powerful autofocus. A High-Response Linear Actuator autofocus system quickly and accurately shifts focus for accurate tracking of fast-moving subjects and rapid switching to a new subject. Thanks to the suppression of focus breathing, the lens is also suitable for professional video creation.
Reliable Optical Stabilization
This lens features a powerful optical image stabilization system that compensates for 6.5 stops of camera shake at the wide end and 4.5 stops at the telephoto end. Powered by Sigma's OS2 algorithm, the stabilization system makes the lens more suitable for on-the-go handheld use, even when shooting in low light and at the long end of the zoom range.
Crystal-Clear Optics
Thanks to one FLD, three SLD, and four aspherical elements, the lens produces sharp final images with accurate colors and minimal distortion for a pleasant shooting experience throughout the entire zoom range, even wide open at f/2.8. A rounded 11-blade diaphragm produces beautiful bokeh with smooth focus falloff that wonderfully highlights the in-focus areas.
Ready for Anywhere
Continue using the lens in inclement weather conditions thanks to the dust- and splash-resistant construction, allowing you to continue photographing with comfort even as clouds roll in. Additionally, the front element features a water- and oil-repellent coating that makes it especially easy to clean.
