Great for Low-Light Shooting. The Sigma 16mm f/1.4 DC DN Contemporary’s fast f/1.4 maximum aperture makes it great for low-light shooting and gives you extensive depth-of-field control for selective-focusing techniques. Its nine-blade curved aperture makes for smooth out-of-focus highlights.

Stepping Autofocus Motor. The stepping motor provides fast, smooth, and nearly silent autofocus operation for stills and video alike.

Advanced Optics. This lens’s thirteen-group/sixteen-element optical design includes three “F” Low-Dispersion elements, two Super Low-Dispersion elements, and two molded aspherical elements to help produce excellent sharpness, color accuracy, and clarity while minimizing aberrations and fringing. Sigma applies a Super Multi-Layer coating to each of the lens elements to combat flare and ghosting for contrasty, color-neutral shots. This all makes for a highly versatile lens that’s been designed from the ground up for crop-frame shooters.

High-Quality Build. The Sigma 16mm’s Thermally Stable Composite build is dust- and splash-resistant, so that that you can use it in adverse conditions. It also boasts a brass bayonet mount for maximum durability.
