Sigma Art 50-100mm F1.8 – Canon EF

Overview
The SIGMA 50-100mm F1.8 DC HSM | Art lens is designed to minimize flare and ghosting, making it resistant to strong incidental light sources. Its Hyper Sonic Motor (HSM) has been enhanced to achieve outstanding image quality and F1.8 brightness. The diaphragm unit is designed for smooth operation and features Carbon Feather film and a new polycarbonate for durability. The lens also has inner focus and inner zoom technologies, making it ideal for videography. The tripod socket is compact and the lens is part of SIGMAs Art line, known for high-level artistic expression. The lens also features a large F1.8 aperture throughout the zoom range and is made with high-quality design features.

The SIGMA 50-100mm F1.8 DC HSM | Art lens is a mid-tele zoom lens that offers prime lens-level image quality and a large F1.8 aperture throughout the zoom range. It was the worlds first APS-C zoom for DSLRs to offer a constant F1.8 aperture value. The lens covers the focal lengths of three prime lenses in one package and sets a new standard for zoom lens image quality. The lens is ideal for portraits with subtle bokeh effects and more, making it a game-changer in the world of photography.

About the Sigma Art 50-100mm F1.8 – Canon EF

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.

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.

Diaphragm unit designed for smooth operation
The diameter of the diaphragm is the second-largest in the SIGMA lens lineup after that of the SIGMA 200-500mm F2.8 / 400-1000mm F5.6 EX DG, necessitating smoother and quicker operation than ever before. To achieve this goal, the diaphragm blades feature Carbon Feather film, and the diaphragm unit features a new polycarbonate made with fluorine. Thanks to these innovations,diaphragm operation is exceptionally smooth even during continuous shooting, while the new polycarbonate is exceptionally durable and wear-resistant.

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.

Tripod socket designed for stable, comfortable operation
The tripod socket is compact, making operation more stable and comfortable during handheld photography. Parts with electro-less nickel plating help ensure the quality and durability of the 90-degree click stops and smooth switching between the horizontal and vertical position. The shape of the socket also enhances ease of handling and carrying when the lens is not attached to a camera.

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.

High-quality design features
To ensure precise operation, internal parts feature generous use of metal and Thermally Stable Composite (TSC),* which is highly compatible with metal parts. The lens barrel is engraved with the year of release for instant access to this information.
