The Sigma 14mm F1.4 DG DN Art is a high-performance ultra-wide-angle lens created for photographers who want to capture expansive scenes with exceptional detail. Its 14mm focal length and bright F1.4 aperture make it particularly suitable for astrophotography, Milky Way photography, night landscapes, architecture, and low-light environments. Featuring an advanced optical design with 19 elements in 15 groups, including FLD, SLD, and aspherical elements, this lens is engineered to deliver sharp images while controlling optical aberrations. Sigma has also carefully corrected sagittal coma flare to help maintain the shape and clarity of stars across the image, even when shooting at wide apertures. The lens features a High-response Linear Actuator (HLA) autofocus system for fast, quiet, and accurate focusing. An 11-blade rounded diaphragm helps produce smooth background rendering, while the durable, dust- and splash-resistant construction supports outdoor photography in challenging conditions. Additional features include an aperture ring, a customizable AFL button, a Manual Focus Lock switch, a lens heater retainer, a rear filter holder, and a removable tripod socket. Whether you are photographing the Milky Way, dramatic landscapes, city architecture, or indoor scenes, the Sigma 14mm F1.4 Art is built for demanding creative work. Available for compatible Sony E-mount and L-Mount full-frame mirrorless cameras. Always confirm the mount version before purchasing.
