The Sigma 14-24mm f/2.8 DG DN Art Lens provides a versatile range of wide-angle focal lengths with excellent image quality while optimizing size and weight. 

An Art-series zoom, this lens is also distinguished by its fast f/2.8 constant maximum aperture to suit working in available lighting conditions. Featuring a sophisticated optical design, a series of low dispersion and aspherical elements is used to minimize both chromatic and spherical aberrations throughout the zoom range in order to achieve high sharpness, clarity, and colour accuracy. A Super Multi-Layer Coating combined with a NanoPorous Coating also helps to suppress lens flare and ghosting to a greater degree than conventional anti-reflective coatings. This helps to more effectively produce colour-accuracy and contrast-rich imagery in a variety of lighting conditions.

Though the full-time manual focus is available, this lens is equipped with a stepping motor that enables smooth, high-speed autofocusing that is notably quiet whether utilizing features such as Face/Eye Detection AF or during video shooting. A built-in Autofocus-Lock (AFL) button can be assigned additional functions to widen the range of operations available on the lens, while inside, a rounded 11-blade diaphragm improves image quality by helping to create smooth bokeh. Additionally, a built-in lens hood serves to protect the front element as well as prevent stray light from causing flare.
