Sigma 50-120mm F2.8 DC OS | C Lens for Fujifilm X 

The Sigma 50-120mm F2.8 DC OS | Contemporary is the definitive large-aperture telephoto zoom lens engineered specifically for APS-C mirrorless systems. Delivering a versatile 35mm-equivalent focal range of approximately 75–180mm, this lens brings professional-tier optical performance and a bright, constant F2.8 aperture into an extraordinarily compact body measuring just 99mm in length and weighing only 390g. It completes Sigma’s holy trinity of constant F2.8 APS-C zoom lenses alongside the 10-18mm and 18-50mm Contemporary lenses.

Built to handle both high-end still photography and cinematic video creation, the optical construction features 1 FLD element, 3 SLD elements, and 4 aspherical elements to control aberrations and deliver outstanding contrast from edge to edge. The lens features an HLA (High-response Linear Actuator) linear motor for rapid, precise autofocus alongside the OS2 optical stabilization system providing up to 6.5 stops of stabilization. Designed with a dust- and splash-resistant structure, a water- and oil-repellent front coating, and a design that minimizes focus breathing, the Sigma 50-120mm F2.8 offers uncompromising mobility without sacrificing professional results.
