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

Be the first to review this product

The Sigma 50-100mm f/1.8 DC HSM Art is a mid telephoto lens for cropped APS-C sensor cameras with a prime-like super-fast maximum aperture of f/1.8 throughout the entire zoom range.

This is the first DSLR zoom lens to cover 3 popular telephoto prime lens focal lengths (85mm, 105mm, and 135 mm (35mm equivalent)) at f/1.8, and is ideal for event photography, where low light performance and reach is critical; as well as subject focused portrait photography.

Furthermore the lens features an hypersonic motor for fast, accurate and near silent autofocus; as well as coatings/special elements to reduce aberrations, ghosting and flares.

Features

Features

Great low light performance

The wide open f/1.8 maximum aperture ensures optimal light performance throughout the entire zoom range so you can get sharp results in extreme light conditions


Spectacular bokeh and super-narrow depth of field

The combination of the telephoto zoom range, fast aperture, 9-blade rounded diaphragm and high quality glass elements makes this lens ideal for photographers who wish to separate their subject from the background.


FLD glass, SLD glass, and high-refractive index, high-dispersion glass

The Sigma 50-100mm Art uses a combination 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 to reduce axial and transverse chromatic aberration. By including one or more low-dispersion element in every element group, this lens ensures outstanding image quality throughout the zoom and focal range.


Hyper Sonic Motor autofocus with full time manual override

The Sigma 50-100mm f1.8 Art features a slimmer and enhanced version of Sigma's Hyper Sonic Motor (HSM) autofocus motor. The motor delivers near-silent, smooth, accurate and fast autofocus that can be manually adjusted without needing to use a mode switch.


Inner focus and inner zoom

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.


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. 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.

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.
