In taking photographs of starry skies or other celestial scenes at night, or of the seashore with a wide perspective, a large-diameter lens is a strong ally, since it allows the capture of a moving subject by adjusting shutter speed without relying on ISO sensitivity. With its full-frame 35mm coverage, 14mm focal length for an ultra-wide angle of view, F2 barrier-breaking F1.8, the SIGMA 14mm F1.8 DG HSM | Art is the true high-speed ultra-wide-angle lens for which so many photographers have been waiting. Although some zoom lenses are available that can cover 14mm, the large diameter delivering F1.8 brightness is a singular advantage. Going beyond fast shutter speed, this lens can capture a swarm of fireflies with crystal clarity, a beautiful bokeh effect, and outstanding control of light streaking.

14mm ultra-wide angle of view and F1.8 brightness
By leveraging its extreme angle of view and the dramatic perspective this creates, an ultra-wide-angle lens can get up close and personal with a subject while at the same time taking in a vast background—an example of photography going beyond normal human vision.

SIGMA 14mm F1.8 DG HSM | Art combines the extremely deep depth of field that comes from an ultra-wide angle of view with the extremely shallow depth of field that comes from F1.8 brightness. The result is a sharply captured subject set against a vast background dramatically blurred with a beautiful bokeh effect. It is a highly impressive mode of photographic expression that until now simply has not existed.

Minimized chromatic aberrations
Three FLD ("F" Low Dispersion) glass elements and four SLD (Super Low Dispersion) glass elements help minimize transverse chromatic aberration, which tends to be noticeable in shots taken with ultra-wide-angle lenses. The result is outstanding image quality from the center of the image to the edges.

Featuring a large-diameter aspherical lens element
The SIGMA 12-24mmF4 DG HSM | Art was the first SIGMA lens to feature a large ?80mm aspherical lens element. Building on the expertise derived from this success, the new lens features a large ?80mm precision-molded glass aspherical lens as its front element. This technology has made possible the 14mm F1.8 specification—the first of its kind.

Serving as the front lens element, the large ?80mm precision-molded glass aspherical lens effectively minimizes distortion. Offering excellent peripheral brightness, this lens delivers outstanding image quality from the center to the edges.

Even at the 14mm ultra-wide-angle of view, F1.8 brightness makes possible a very shallow depth of field with the subject standing out dramatically against a bokeh background. Its the unique mode of expression that only a large-diameter lens can deliver.
