Offering the highest level of image quality, this large-aperture F1.8 standard lens stimulates the desire to create

Introducing SIGMA’s second APS-C format zoom lens offering a large F1.8 aperture throughout the zoom range. A mid-tele zoom lens delivers prime lens-level image quality with a large F1.8 aperture throughout the zoom range. SIGMA was determined to create a zoom lens that offers the same brightness and resolution as a fixed focal length lens: in other words, the highest level of optical performance and expressive power. The first result of this challenge was the SIGMA 18-35mm F1.8 DC HSM | Art. In addition to fulfilling the exacting requirements of SIGMA’s Art line, this lens was the world’s first APS-C zoom for DSLRs to offer a constant F1.8 aperture value throughout the zoom range. Building on this concept, SIGMA has developed the new SIGMA 50-100mm F1.8 DC HSM | Art lens, a large-diameter mid-range telephoto zoom lens. While offering even greater brightness than a F2.8 telephoto zoom, this lens covers the focal lengths of three prime lenses in one package: 85mm F1.8, 105mm F1.8, and 135 mm F1.8 (35mm equivalent). A true game-changer, this lens is ideal for portraits with subtle bokeh effects and more, and it sets a new standard for zoom lens image quality.

Technologies that realize Art line image quality in a zoom lens

FLD glass, SLD glass, and high-refractive index, high-dispersion glass help minimize aberrations

To help minimize axial and transverse chromatic aberration, this lens features an optimal arrangement of three FLD (“F” Low Dispersion) glass elements, one SLD (Special Low Dispersion) glass element, three high-refractive index SLD glass elements, and one high-refractive index, high-dispersion glass element. By including one or more low-dispersion element in every element group, this lens ensures outstanding image quality throughout the zoom and focal range.

* FLD glass is ultra-low-dispersion glass that offers performance of the highest level. Highly transparent, its refractive index and dispersion are extremely low as compared to conventional types of glass. It offers characteristics very similar to those of fluorite, which is valued for its high anomalous dispersion. These characteristics minimize residual chromatic aberration (secondary spectrum), which cannot be corrected by ordinary optical glass, while helping to produce sharp, high-contrast images.

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.

Featuring a newly designed Hyper Sonic Motor

To achieve outstanding image quality and F1.8 brightness, SIGMA has enhanced its Hyper Sonic Motor (HSM). Optimizing the layout as well as the shapes of the individual parts, SIGMA has made the HSM 30 percent slimmer than before. In turn, this slimmer HSM has made possible the combination of F1.8 brightness and high image quality in a zoom lens.

Outstanding zoom lens manoeuvrability

Inner focus and inner zoom

Since its release, the SIGMA 18-35mm F1.8 DC HSM | Art has been widely used for videography. Understanding that the SIGMA 18-35mm F1.8 DC HSM | Art and new SIGMA 50-100mm F1.8 DC HSM | Art will often be used together, SIGMA has made the style of operation the same for both lenses, including the feel of focusing and zooming. Thanks to SIGMA’s inner focus and inner zoom technologies, adjusting the focus and zoom rings does not change the length of the lens, and turning the zoom ring is not prone to cause focus shift.

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-life’s, 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.
