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

Sigma 18-50mm f/2.8 DC DN Contemporary Lens (Sony E-Mount)
The Sigma 18-50mm f/2.8 DC DN Contemporary is an ultra-compact, lightweight standard zoom lens engineered specifically for APS-C format Sony E-mount mirrorless cameras. Providing a highly versatile 27-75mm full-frame equivalent focal range, this pocket-sized powerhouse serves as the ultimate everyday workhorse for a wide array of photo and video applications, including landscapes, street scenes, portraits, architecture, and live events.

By combining a bright, constant f/4 maximum aperture with advanced optical glass elements, Sigma has created a fast standard zoom that delivers professional-tier edge-to-edge sharpness without the restrictive weight or bulk of traditional fast zooms.

Constant f/2.8 Aperture & Elite Optical Engineering
Versatile 27-75mm Equivalent Range: Perfectly spans from a spacious wide-angle field of view to a compressed short-telephoto portrait perspective, letting you fluidly adapt to changing environments without a lens change.

Constant f/2.8 Maximum Aperture: Maintains its bright f/2.8 light-gathering performance across the entire zoom track. This allows you to retain identical exposure settings while zooming, excels in low-light environments, and provides extensive control over shallow depth-of-field separation.

Glass-Molded Aspherical Elements: Incorporates three high-precision glass-molded aspherical elements to drastically limit geometric distortions and spherical aberrations, contributing to excellent structural contrast and sharp resolution.

Special Low Dispersion (SLD) Glass: Features one specialized SLD glass element configured to aggressively eliminate chromatic aberrations and color fringing for pristine clarity and color neutrality.

Super Multi-Layer Coating: Optical surfaces are treated with a multi-layered coating to actively suppress ghosting and lens flare, ensuring high contrast and clean color reproduction when working in harsh, direct backlighting.

Rounded 7-Blade Diaphragm: Built with a circular seven-blade iris configuration that yields a smooth, naturally rounded background blur (bokeh) when employing selective focus techniques.

Silent Autofocus Tracking & 1:2.8 Macro Close-Focusing
Whisper-Quiet Stepping AF Motor: Outfitted with an agile stepping motor that drives exceptionally fast, precise, and nearly silent autofocus tracking. This whisper-quiet performance is highly beneficial for capturing video tracks without picking up gear drive noise, shooting in sound-sensitive environments, or tracking fast-moving subjects like children and pets.

Macro-Style Close-Up Power: Boasts an incredibly tight minimum focusing distance of just 4.8 inches (12.1 cm) at the wide end, paired with a high 1:2.8 maximum magnification ratio. This allows you to step directly into macro territory to capture intricate textures and close-up subject detail.

In-Camera Aberration Sync: Fully compatible with native Sony camera bodies to utilize in-camera electronic correction profiles, working in tandem with the glass formula to automatically eliminate peripheral vignetting and linear distortion.
