The Sigma 30mm f/1.4 DC DN | Contemporary is part of Sigma's legendary trio of f/1.4 mirrorless primes. It balances a lightweight, travel-friendly build with image quality that rivals much more expensive professional lenses. The bright f/1.4 maximum aperture not only excels in dim environments but also produces a beautiful, soft bokeh that makes it ideal for portraits, street photography, and everyday snapshots. Optically, the lens is built with nine elements in seven groups, including two aspherical elements and one high-refractive index element to minimize distortion and spherical aberrations. For videographers and hybrid shooters, the stepping motor (STM) ensures fast, near-silent, and smooth autofocus that supports Nikon’s Face and Eye-Detection systems. The lens is constructed from Thermally Stable Composite (TSC) for durability in varying climates and features a dust- and splash-resistant brass mount with rubber sealing for added protection during outdoor use.
