The definitive wide-aperture ultra-wide-angle zoom lens

Setting a new standard for excellence in ultra-wide-angle lenses

Leveraging major manufacturing advances at the Aizu factory, SIGMA is now producing ultra-high-precision molded glass aspherical lens elements as large as φ80mm and incorporating them in new products. This premier optical technology promises to set a new standard for excellence in ultra-wide-angle lenses.

For the Art line, SIGMA began development simultaneously of two ultra-wide-angle lenses offering the key focal length of 14mm: one prime, and one zoom. In 2017, the company launched the 14mm F1.8 DG HSM | Art as the ultimate ultra-wide-angle prime lens. This lens offers outstanding image quality in combination with F1.8 brightness.

Now SIGMA is introducing the 14-24mm F2.8 DG HSM | Art as the ultimate ultra-wide-angle zoom. While minimizing distortion, this lens offers outstanding F2.8 brightness throughout the zoom range and delivers top-level image quality at every focal length and every shooting distance. For these reasons, it is the definitive large-diameter ultra-wide-angle zoom lens.

Outstanding Art line image quality

Designed to team up with 50-megapixel-plus cameras

Designed to team up with 50-megapixel-plus cameras and offer top-level optical performance throughout the zoom range, the 14-24mm F2.8 DG HSM | Art incorporates three FLD glass elements, three SLD glass elements, and three aspherical lens elements, including one large-diameter aspherical element. Effective distribution of these high-refractive-index glass elements further enhances the corrective effect of the FLD and SLD glass. This optical system minimizes transverse chromatic aberration and other optical aberrations, resulting in outstanding high-resolution image quality.

The first element in the optical system is a large-diameter aspherical lens. Optimizing the power distribution of this and the other lens elements minimizes distortion to 1% or lower.* As a result, points of light appear as points without streaking from the center of the image to the edge, and the light volume is also abundant throughout the frame. In addition, simulations performed from the design stage onward have helped minimize flare and ghosting. In combination, these technologies ensure excellent ultra-wide-angle performance.

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 an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.

Compatible with Canon Lens Aberration Correction*

The Canon mount lens is compatible with the Canon Lens Aberration Correction function. Matching the optical characteristics of the lens, these functions perform in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more.

* Function not available on all Canon cameras. Further, available corrections may vary by Canon camera model.

Professional specifications

Allowing photographers to work in all types of weather

Like SIGMA’s Sports line lenses, the 14-24mm F2.8 DG HSM | Art features a highly effective dust- and splash-proof structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection, allowing photographers to work in all types of weather. In addition, the front of the lens is protected by a water- and oil-repellent coating that makes cleaning easy. The high-speed, high-accuracy autofocus helps photographers react in an instant to get those special shots.

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.

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.

Rounded diaphragm

The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

Introducing new Front Conversion Service

Today’s virtual reality creators favor multi-camera videography that leverages the capability of ultra-wide-angle lenses. Addressing this trend, SIGMA is offering the new Front Conversion Service (charges apply), in which SIGMA converts the petal-type hood of the 14-24mm F2.8 DG HSM | Art lens to an exclusive round component. This altered front structure allows the lens to be deployed with greater freedom in multi-camera VR videography. The new front also helps prevent the lens from interfering with other lenses or from casting a visible shadow. The use of this service has no impact on the validity of the product warranty.

New SIGMA GLOBAL VISION product lines are setting new benchmarks for image quality

Evaluation with SIGMA's own MTF measuring system: A1

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 14-24mm F2.8 DG HSM | Art lenses are checked using this A1 system before they are shipped.

* A1:Aizu 1

46-megapixel Foveon direct image sensor

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.

Ultra-high precision and quality—all made in Japan.

With only a few minor exceptions, all of SIGMA's manufacturing, including molds and parts, takes place under a single integrated production system in Japan. We are now one of the very few manufacturers whose products are truly made in Japan. We like to think our products are somehow imbued with the essence of our homeland, blessed as it is with clean air and water, and focused, hard-working people. We pride ourselves on the authentic quality of SIGMA products, born of a marriage between highly attuned expertise and intelligent, advanced technology. Our sophisticated products have satisfied professionals and lovers of photography all over the world because our manufacturing is based on genuine craftsmanship, underpinned by the passion and pride of our experts.
