Built for Creators Who Demand More

Meet your next go-everywhere lens. The Sigma 18-50mm f/2.8 DC DN Contemporary is a compact, lightweight standard zoom engineered specifically for APS-C Sony E-mount mirrorless cameras — delivering a 27-75mm full-frame equivalent range that handles everything from sweeping landscapes and moody street scenes to sharp portraits and event coverage.

What sets this lens apart is its constant f/2.8 aperture across the entire zoom range, giving you reliable low-light performance and beautiful background separation no matter where you set your focal length. Sigma's optical formula uses three high-precision glass-molded aspherical elements alongside a Special Low Dispersion (SLD) element to suppress distortion, chromatic aberrations, and color fringing — all while keeping the lens refreshingly small and light.

Fast, Quiet, and Surprisingly Close

A stepping motor drives autofocus that is nearly silent and impressively quick, making this lens equally at home shooting fast-moving kids, animals, or rolling video without disruptive noise. A minimum focusing distance of just 4.8 inches with a 1:2.8 maximum magnification ratio opens the door to compelling close-up and macro-style shots. The Super Multi-Layer Coating controls flare and ghosting in harsh lighting, while the rounded seven-blade diaphragm renders out-of-focus areas with smooth, pleasing bokeh. In-camera aberration correction rounds out the package for consistently polished results.
