The Sigma 10-18 mm F2.8 DC DN is a fast ultra-wide-angle zoom for mirrorless APS-C cameras. It offers an effective focal length of 15 to 27 mm (equivalent to 35 mm) and enables expressive images, regardless of whether you are photographing landscapes, architecture, interiors or portraits. The lens is characterised by its high optical quality, which is achieved through the use of aspherical lenses and special glass lenses with low dispersion. The lens has a fast AF stepping motor and a developed, clip-on 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 characterised by an enlarged angle of view that is superior to that of our eyes. It differs from normal lenses due to its shorter focal length. This shorter focal length increases the angle of view, the subjects appear smaller and more can be depicted in the photo. The wide-angle lens also creates a clearly visible effect of spatial depth - objects in the distance appear even further away, giving your pictures an impressive sense of depth.
