Sigma 14mm F1.4 DG DN Art Overview
The Sigma 14mm F1.4 DG DN Art is a professional ultra-wide-angle prime lens designed for full-frame mirrorless cameras. Featuring an exceptionally bright f/1.4 aperture, it is purpose-built for astrophotography while also excelling in landscapes, architecture, interiors, environmental portraits, and cinematic video production. Sigma engineered this lens to deliver outstanding corner-to-corner sharpness and minimal optical aberrations, even when shooting wide open.
As part of Sigma's premium Art series, the lens incorporates advanced optical elements that significantly reduce sagittal coma flare, chromatic aberration, flare, and ghosting—critical for capturing pinpoint stars and high-contrast night scenes. The ultra-wide 114.2° angle of view combined with the fast aperture enables dramatic perspectives and exceptional low-light performance.
Designed with photographers in mind, the lens includes a Manual Focus Lock switch, removable Arca-Swiss compatible tripod foot, lens heater retainer, rear filter holder, aperture ring, and weather-resistant construction, making it one of the most capable ultra-wide lenses available for mirrorless systems.
