Sigma AF 16-28mm F2.8 DG DN Contemporary Lens for Sony

The 16-28mm DG DN Contemporary is engineered to provide "Art-level" sharpness in a Contemporary-series size. Its optical construction includes 16 elements in 11 groups, featuring five FLD (F Low Dispersion) glass elements and four aspherical lens elements. This advanced layout is specifically designed to suppress chromatic aberrations and field curvature, ensuring your wide-angle shots are sharp from edge to edge. To handle difficult lighting, it utilizes Sigma’s Super Multi-Layer Coating to effectively minimize ghosting and flare. For videographers and street photographers, the lens is equipped with a high-speed stepping motor that provides near-silent and highly responsive autofocus. Because it zooms internally, the lens doesn't suck in dust or change balance during use, and the front element remains stationary, allowing for the easy use of 72mm screw-in filters—a major benefit over many ultra-wide zooms with bulbous front glass. The body is constructed from Thermally Stable Composite (TSC), ensuring precision even in extreme temperature shifts, and features a dust and splash-resistant brass mount for reliable outdoor use.
