Sigma 14-24mm f2.8 for Sony E mount provides a versatile range of wide-angle focal lengths with excellent image quality while optimizing size and weight. The 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 minimizes chromatic and spherical aberrations throughout the zoom range to achieve high sharpness, clarity, and colour accuracy. A Super Multi-Layer Coating combined with a Nano Porous Coating also helps to suppress lens flare and ghosting to a greater degree than conventional anti-reflective coatings. This helps to produce colour accuracy and contrast-rich imagery more effectively in various lighting conditions and is also 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.
