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.
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.
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.
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.
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.
Serving as the front lens element, the large φ80mm precision-molded glass aspherical lens effectively minimizes distortion. Offering excellent peripheral brightness, this lens delivers outstanding image quality from the center to the edges.
The SIGMA 12-24mmF4 DG HSM | Art was the first SIGMA lens to feature a large φ80mm 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.
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.
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.
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.
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.
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.
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.
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
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
Mount Converter MC-11 allows you to use your SIGMA SA mount and SIGMA EOS mount (Canon-compatible) interchangeable lenses with the Sony E-mount camera body. Enjoy the world of ultra-wide-angle photography with Sony E-mount cameras.
With the optional SIGMA USB DOCK, you can update your lens firmware and adjust the focus position and other settings. Simply connect the lens to the SIGMA USB DOCK and the dock to a computer to use the dedicated SIGMA Optimization Pro software and perform various types of customization and adjustment.
We used to measure lens performance with a Modulation Transfer Function (MTF) measuring system using conventional sensors. However, we have developed our own proprietary MTF measuring system (A1)* using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections. All SIGMA 14mm F1.8 DG HSM | Art lenses are checked using this A1 system before they are shipped.

The 46 effective megapixel (4,800 × 3,200 × 3 layers) and 44 recording megapixel (4,704 × 3,136 × 3 layers) 23.5 × 15.7mm APS-C X3 direct image sensor captures all primary RGB colors at each and every pixel location, ensuring the capture of full and complete color. Using three silicon-embedded layers of photo detectors, stacked vertically to take advantage of silicon's ability to absorb red, green and blue light at different respective depths, it efficiently reproduces color more accurately, and offers sharper resolution, pixel for pixel, than any conventional image sensor. Since color moiré is not generated, the use of a low-pass filter is not required, meaning light and color, generated by the 46-megapixel APS-C X3 direct image sensor is captured with a three-dimensional feel
