Uncompromising optical performance in an exceptionally compact body
The definitive large-aperture telephoto zoom for APS-C cameras

The Sigma 50-120mm F2.8 DC OS | Contemporary is a large-aperture telephoto zoom lens for APS-C cameras with an exceptionally compact, lightweight design. At a constant F2.8 aperture, it covers the telephoto range of approximately 75mm to 180mm in 35mm equivalent terms. High-end functionality is paired with the portability and mobility an APS-C lens demands, in a remarkably compact body measuring 99mm in length and weighing just 390g^*. The large bokeh and compression effect that only a telephoto lens can deliver allow it to perform across a wide range of scenes, from portrait sessions to outdoor events. Together with the Sigma 10-18mm F2.8 DC DN | Contemporary and Sigma 18-50mm F2.8 DC DN | Contemporary already on the market, it completes a full-fledged, high-image-quality zoom series covering ultra-wide-angle to telephoto at a constant F2.8, setting a new standard for APS-C zoom lenses.
