Sigma 14mm f/1.8 ART DG HSM Lens (for Canon EOS)
The world's first f/1.8 ultra-wide-angle lens.
With its full-frame 35mm coverage, 14mm focal length for an ultra-wide angle of view, f/2 barrier-breaking f/1.8 aperture, the Sigma 14mm f/1.8 ART DG HSM Lens 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 f/1.8 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. 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.
14mm Ultra-Wide Angle of View and f/1.8 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. The Sigma 14mm f/1.8 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 f/1.8 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.
Seventh 35mm Full-Frame Prime Lens to Join the Art Line:
Launched in 2012, the Sigma 35mm f/1.4 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 f/1.8 DG HSM ART is the seventh prime lens in the line that offers 35mm full-frame coverage. Now even stronger, the Art line sets the new standard for prime lenses in the ultra-high-megapixel era.
Featuring a Large-Diameter Aspherical Lens Element:
The Sigma 12-24mm f/4 DG HSM Art was the first Sigma lens to feature a large 8mm 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 f/1.8 specification -- the first of its kind.
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.
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, f/1.8 brightness makes possible a very shallow depth of field with the subject standing out dramatically against bokeh background. It's the unique mode of expression that only a large-diameter lens can deliver.
Exclusive Low-Dispersion Glass:
The degree to which light is refracted by glass depends on the light's wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as "secondary spectrum" may still remain. To minimize this secondary spectrum, which can be a serious issue with conventional lenses, Sigma lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD ("F" Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass and optimization of power distribution gives Sigma lenses superlative image rendition undiminished by residual chromatic aberration.
Designed to Minimize Flare and Ghosting:
From the start of the design process, Sigma measured flare and ghosting to establish an optical design that is resistant to strong incidental light sources such as backlight. At the prototyping stage, Sigma used not only simulations but actual photographic experiments to assess flare and ghosting under multiple criteria, identify the causes of these issues under a wide range of situations, and take measures to mitigate them. In addition, Sigma's Super Multi-Layer Coating helps further reduce flare and ghosting and provide sharp, high-contrast images even in backlit conditions.

Delivering Fast Autofocus Photography:
The large HSM (Hyper-Sonic Motor) delivers ample torque to the focusing group for outstanding speed, ensuring exceptionally stable performance even at lower speeds. Along with the optimized AF algorithm, this feature delivers fast autofocus photography. In addition, the focus limiter makes AF highly responsive to distance from the subject for even more nimble performance.
Fast AF with Full-Time Manual Focus:
Full-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring.
High-precision, Rugged Brass Bayonet Mount:
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
Mount with Dust- and Splash-Proof Design:
Since the area of the lens most vulnerable to dust and other foreign bodies is the mount, rubber sealing helps provide peace of mind. In addition, the front lens element features a water- and oil-repellent coating that helps the lens perform well in the rain, near water, and in other challenging conditions.
