Sigma 16-28mm f/2.8 DG DN Contemporary Lens (Sony E)

Sigma 16-28mm f/2.8 DG DN Contemporary Lens
Compact Ultrawide Zoom – Fast Constant f/2.8 Aperture, Internal Zoom & Stepping AF Motor

The Sigma 16-28mm f/2.8 DG DN Contemporary is an ultra-compact, high-performance wide-angle zoom lens designed for full-frame mirrorless camera systems. Providing a versatile ultrawide focal range in a lightweight, portable package, this lens pairs an expansive field of view with a fast constant f/2.8 maximum aperture. The bright aperture allows for faster shutter speeds in low-light environments while rendering smooth, shallow depth-of-field close-ups.

Optically engineered to maintain edge-to-edge sharpness, the lens features two large-diameter aspherical elements alongside low-dispersion glass to eliminate chromatic aberrations and spherical distortions. Super Multi-Layer and Nano Porous Coatings are applied to suppress lens flare and ghosting when shooting in direct light. A key highlight for videographers, landscape photographers, and gimbal operators is the internal zoom and focus architecture, which keeps the total physical length unchanged during operation to preserve rig balance. Focusing is driven by a fast, quiet stepping AF motor with full-time manual focus override, housed within a weather-resistant barrel with a durable brass bayonet mount.
