14mm F1.8 DG HSM Art The SIGMA Corporation is proud to announce the SIGMA 14mm F1.8 DG HSM Art lens, 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.

Art line delivers high-level artistic expression SIGMA is organizing all its interchangeable lenses into three product lines: Contemporary, Art, and Sports, each with a distinctive concept. Designed with a focus on sophisticated optical performance and abundant expressive power, our Art line lenses deliver high-level artistic expression. Offering astonishing rendering performance that meets the highest standard, they are perfect for landscapes, portraits, still-lifes, close-ups, and casual snaps. They are made for the kind of photography that unleashes the inner artist. A powerful ally in every genre of photography, SIGMA's Art line lenses excel both in the studio for formal works and outdoors for impressive shots of architecture, starry skies, and many other scenes. 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. 14mm ultra-wide-angle and F1.8 brightness: a new dimension of visual experience A mode of expression that was unavailable—until now 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’s a highly impressive mode of photographic expression that until now simply hasn’t 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. Offering excellent peripheral brightness, this lens delivers outstanding image quality from the center 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 f80mm 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 f80mm 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. 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. Delivering fast autofocus photography An ultra-wide-angle lens that gives the photographer satisfying control A large HSM, AF with full-time manual focus and all of SIGMA’s latest design and manufacturing technologies help deliver an entirely new visual experience. Large HSM for smooth operation at lower speeds The large hypersonic motor (HSM) 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. Nikon electromagnetic diaphragm mechanism included The Nikon mount version of this lens includes an electromagnetic diaphragm mechanism that allows it to receive the appropriate signals from the camera body. This feature ensures precision diaphragm control and stable Auto Exposure (AE) performance during continuous shooting. * Functionality may be limited on some camera bodies. 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. * Note: The operation of full-time MF may vary based on mount type. 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-repellant coating that helps the lens perform well in the rain, near water, and in other challenging conditions. * Except for SIGMA mount Specifications All figures calculated by SIGMA.
