Sigma 50-100mm f/1.8 DC HSM Art Lens Nikon F

Outstanding Zoom Lens Maneuverability

Thanks to SIGMA’s inner focus and inner zoom technologies, adjusting the focus and zoom rings on the Sigma 50-100mm f/1.8 DC HSM Art Lens for Nikon does not change the length of the lens, and turning the zoom ring is not prone to cause focus shift.

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. As with the previous SIGMA HSM, at any time during AF, users may access MF simply by rotating the focus ring. This feature makes faster focus adjustment possible, since there is no need to use the AF/MF focus mode switch. Also, the optional SIGMA USB DOCK allows the user to set the lens to conventional full-time manual focus override.

An APS-C Format Mid-Tele Zoom Lens
Offering 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 for Canon, 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.

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.

Diaphragm Unit Designed For Smooth Operation

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.

What is HSM on a Sigma lenses?

Lens that use the abbreviation HSM(Hyper Sonic Motor) use a very fast and silent motor to drive the autofocus system.

What does DG stand for on Sigma lenses?

DG is use to indicate that the lens is designed for a full frame camera (DG lenes can be used on a crop sensor camera). DC is for crop sensors (These typically cannot be used on a full frame camera)

What is the Sigma Art range?

Sigma Art lenes are designed to have fast aperture and incredibly sharp images
