Sigma 18-50mm f/2.8 DC DN Contemporary Lens for Sony E

Versatile Standard Zoom Range

18–50mm zoom (27–75mm full-frame equivalent) covers everyday shooting needs from wide-angle scenes to tighter portraits and detail shots.

Constant f/2.8 Aperture

Bright f/2.8 aperture throughout the zoom range for consistent exposure, smoother background separation, and better low-light performance.

Advanced yet Lightweight Optics

Three glass-molded aspherical elements and one SLD element deliver high sharpness and reduced aberrations, while keeping the lens compact and weighing only about 10.2 oz (290 g).

Super Multi-Layer Coating

Reduces flare and ghosting for improved contrast and accurate color rendering when shooting in strong or backlit conditions.

Quiet Stepping Motor AF

Fast, nearly silent autofocus performance that’s ideal for video, vlogging, and shooting in quiet environments while still tracking moving subjects with ease.

Close-Focus, Macro-Style Shooting

Minimum focusing distance of just 4.8" / 12.1 cm and 0.36x magnification (1:2.8) make it great for close-ups of food, products, and everyday details.

Smooth 7-Blade Rounded Bokeh

Rounded 7-blade diaphragm helps produce smooth, pleasing bokeh and attractive out-of-focus highlights at wider apertures.

Dust- and Splash-Resistant Design

Contemporary-series construction with sealing against dust and splashes adds reliability when shooting on location, supported by the included LH582-02 lens hood.
