SIGMA 14mm F1.8 DG HSM

Introducing the world’s first and only F1.8 ultra-wide-angle lens

A true high-speed lens that delivers a new dimension of visual experience

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.

Key features

14mm ultra-wide angle of view and F1.8 brightness deliver a new dimension of visual experience 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.

Minimized distortion

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.

Distinctive bokeh effect

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. It’s the unique mode of expression that only a large-diameter lens can deliver.

Seventh 35mm full-frame prime lens to join the Art line

Launched in 2012, the SIGMA 35mm F1.4 DG HSM | Art was the first lens in the Art line. Since then, SIGMA has developed a wide variety of lenses for the line, and the SIGMA 14mm F1.8 DG HSM | Art is the seventh prime lens in the line to offer 35mm full-frame coverage. Now even stronger, the Art line sets the new standard for prime lenses in the ultra-high-megapixel era.

Review

f/4 and f/5.6 are the sharpest apertures of the lens. In the center of the frame detail is very sharp at all apertures, with a minor fall-off at f/16 because of diffraction.

With the lens focused in the middle of the picture, there is softness in the edges of the frame in images shot at f/1.8 and f/2. This is more of a depth of field issue - the softness represents out of focus areas rather than poor edge quality.

New lens firmware

This firmware allows compatibility with Canon’s in-camera Lens Aberration Correction function to enable correction matching the optical characteristics of each lens. It also corrects the phenomenon that abnormal images appear or operation errors occur when the function is enabled. This firmware also corrects the phenomenon whereby the continuous shooting speed decreases in certain combinations with some cameras when used with the 14-24mm F2.8 DG HSM | Art for Canon, and the phenomenon whereby the AF speed occasionally becomes unstable when used with the 100-400mm F5-6.3 DG OS HSM | Contemporary for Canon.

For customers who own the SIGMA USB DOCK and applicable products listed below, please update the firmware via SIGMA Optimization Pro. Before updating the firmware using the SIGMA USB DOCK, please ensure to update SIGMA Optimization Pro to Ver. 1.4.1 or later for Windows, and Ver. 1.4.0 or later for Macintosh.

Applicable Products

• SIGMA 14mm F1.8 DG HSM | Art for CANON
