Sigma 14mm f/1.8 DG HSM Art Lens for Sony E

The Sony E-mount 14mm f/1.8 DG HSM from Sigma is a unique wide-angle prime designed to produce high-resolution, well-corrected imagery. As part of the Art line of lenses, this lens has a focus on image quality and rendering and utilizes both FLD and SLD glass elements to control chromatic aberrations and color fringing for notable clarity. Four aspherical elements, including the front large-diameter precision-molded glass element, also contribute to reducing distortion and spherical aberrations for improved sharpness and accuracy. Additionally, a Super Multi-Layer Coating has been applied to individual elements to suppress lens flare and ghosting for greater contrast when working in strong lighting. This focusing motor also enables full-time manual focus override at any time just by rotating the focus ring for refined manual control and focusing as close as 10.6". The lens barrel is constructed using a Thermally Stable Composite material, which supports working in a wide variety of temperatures and conditions, and the lens mount is constructed from brass for long-term durability and mounting accuracy. A prime wide-angle lens is designed for full-frame Sony E-mount mirrorless cameras, however, it can also be used with APS-C models where it will provide a 21mm equivalent focal length. Three F Low Dispersion (FLD) and four Special Low Dispersion (SLD) elements are featured in the optical design and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy. A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions. The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations.
