Our take on the Sigma AF 50-120MM F/2.8 DC OS Contemporary Lens

A constant-aperture telephoto zoom for APS-C mirrorless cameras, covering roughly 75-180mm in full-frame terms. The F2.8 aperture holds across the zoom range, which helps in low light and gives soft background blur for portraits. It is light at 390g and short at 99mm, with dust and splash resistance and a water- and oil-repellent coating. The HLA linear motor drives fast autofocus. Rivals in this class are mostly slower variable-aperture zooms or larger, heavier constant F2.8 lenses.

About the Sigma AF 50-120MM F/2.8 DC OS Contemporary Lens

The Sigma 50-120mm F2.8 DC OS | Contemporary is a telephoto zoom lens for APS-C mirrorless cameras. Its focal length range is equivalent to approximately 75-180mm in 35mm terms. It has a constant F2.8 aperture, which supports low-light shooting and gives soft background blur.
