The Sigma 10-18 mm F2.8 DC DN is a bright ultra-wide-angle zoom lens designed for mirrorless APS-C cameras. It offers an effective focal length of 15 to 27 mm (equivalent to 35 mm) and allows for expressive images, whether you're photographing landscapes, architecture, interiors, or portraits. The lens is characterized by high optical quality, achieved through the use of aspherical lenses and special low-dispersion glass elements. It features a fast AF stepping motor and a developed, detachable lens hood that reduces stray light. The lens is available for L-Mount, Sony E-Mount, and Fujifilm X-Mount.

The wide-angle lens is distinguished by an expanded field of view that surpasses that of the human eye. It differs from standard lenses due to its shorter focal length. This shorter focal length increases the field of view, making subjects appear smaller and allowing more to be captured in the photo. Additionally, the wide-angle lens creates a well-defined sense of spatial depth—objects in the distance appear even further away, giving your images a striking sense of depth layering.
