The performance and functionality that pros in all fields require

What photographers demand from the 24-70mm F2.8 specification is much more than than outstanding image quality. They want all the features that make this a go-to lens for a broad range of photographic opportunities, including optical design ideal for the latest ultra-loftier-megapixel digital cameras, hypersonic motor (HSM) for high-speed autofocus, optical stabiliser (Os) with powerful stabilisation consequence, dust- and splash-proof mountain with prophylactic sealing and a metal barrel for a stable, rigid feel. This all-new 24-70mm F2.viii lens from SIGMA delivers the functioning and functionality that help pros succeed in news, nature, and many other fields of photography.

Art line delivers high-level artistic expression

SIGMA is organising all its interchangeable lenses into iii production lines: Contemporary, Art, and Sports, each with a distinctive concept. Designed with a focus on sophisticated optical functioning and abundant expressive power, Sigma'due south Art line lenses evangelize high-level artistic expression. Offering astonishing rendering operation 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 compages, starry skies, and many other scenes.

SIGMA's Art line: a focus on high resolution

To fulfill the uncompromising epitome quality standard of the Art line, this lens features a power distribution that has been optimised in exacting detail. This is the lens for those who desire consistent resolution at maximum F2.eight brightness or lower and complete control of the cute bokeh outcome.

Outstanding optical performance

Iii SLD glass lens elements and iv aspherical lens elements help minimise optical aberrations. To ensure outstanding prototype quality from the centre to the edges of the photo, the optical organisation minimises coma, which causes points of light to streak, and transverse chromatic abnormality, which cannot be corrected by adjusting the discontinuity. The optical system as well minimises distortion, which tin exist specially evident in wide-angle shots, resulting in excellent optical performance throughout the zoom range.

A 24-70mm F2.8 lens that meets the high standards of the Art line

SIGMA has continuously pioneered 24-70mm F2.8 lenses that are a step ahead of the times. The first model of this specification, SIGMA 24-70mm F2.viii EX DG ASPHERICAL DF, launched in 2001. Representing the fourth generation of the family, the SIGMA 24-70mm F2.8 DG Bone HSM | Art accomplishes a challenging feat in optical design: incorporating optical stabiliser functionality in a large-diameter standard zoom. By leveraging all of its blueprint and manufacturing expertise, SIGMA has ensured that this new lens fulfills the uncompromising requirements of the Art line for image and build quality.

Bokeh that is a cut above

At wide-open aperture, this lens offers outstanding photographic expression. The area in focus is extremely abrupt, while the background exhibits a cute bokeh effect with only slight spherical aberration. Since large-diameter zoom lenses are ofttimes used at wide-open aperture, SIGMA has paid close attention to the shape of the bokeh, aiming for perfect circularity.

Incorporating advanced aspherical lens processing applied science

Building on the success of its predecessors, the SIGMA 24-70mm F2.8 DG Os HSM | Art incorporates an aspherical lens element that helps achieve extremely loftier resolution. This element is much thicker at the center than the edges, and forming its unusual shape is a feat of manufacturing applied science. Moreover, SIGMA processes the surface of this aspherical lens element with ultra-precise tolerances that are measured in hundredths of a micrometer. This extremely fine surface allows the SIGMA 24-70mm F2.viii DG Os HSM | Art to deliver a very natural and smooth bokeh outcome, without the visible concentric rings that afflict typical aspherical lens elements.

Exclusive low-dispersion glass

The degree to which lite is refracted past drinking glass depends on the light's wavelength. This fact causes different colours of low-cal to focus at slightly unlike points. The result is chromatic abnormality, the color fringing that is specially noticeable in telephoto lenses. Most chromatic aberration tin can be removed by combining a loftier-refractivity convex lens chemical element with a low-refractivity concave element. Yet residual chromatic aberration known as "secondary spectrum" may still remain. To minimise this secondary spectrum, which tin can be a serious result with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offer superior operation: 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 dissonant dispersion characteristics of fluorite. Meticulous deployment of these types of sectional depression-dispersion glass and optimisation of power distribution gives SIGMA lenses top image rendition undiminished by rest chromatic

Designed to minimise flare and ghosting

From the first of the design process, SIGMA measured flare and ghosting to plant an optical design that is resistant to potent incidental light sources such every bit backlight. At the prototyping stage, SIGMA used non only simulations but actual photographic experiments to appraise flare and ghosting under multiple criteria, identifying the causes of these issues nether a wide range of situations, and taking measures to mitigate them. In addition, SIGMA's Super Multi-Layer Blanket helps further reduce flare and ghosting and provide sharp, high-contrast images even in backlit conditions.

OS functionality, newly designed HSM, dust/splash-proof construction, and more than

This lens has all the features and functions photographers need to be successful on a wide diversity of shoots. In add-on to outstanding image quality, this lens offers autofocus, structure that minimises the incursion of grit and debris, an optical stabiliser (Bone) office and more. To make this lens as like shooting fish in a barrel to employ past photographers in all fields, information technology features not only SIGMA's most avant-garde mechanical systems but also the company's latest software.

Incorporating the Bone function for success on whatever shoot

Designed for avant-garde utility in a wide diversity of situations, the optical stabiliser (OS) offers a powerful stabilisation effect.

Newly designed HSM for fast AF performance

The newly designed hypersonic motor (HSM) offers i.three times the torque of its predecessor. Fifty-fifty at low speeds, it offers exceptionally stable performance.

Fast AF with total-time manual focus

Full-time manual focus function allows the lens to be switched to manual focus simply past rotating the focus ring.

Lens barrel designed for loftier rigidity

Since big-diameter standard zoom lenses tend to serve as a go-to lens and see frequent use, the SIGMA 24-70mm F2.8 DG Os HSM | Art is designed to stand up upward to the challenging shooting environments that pros run into. To this cease, the lens barrel contains a large amount of metallic, while the external moving parts feature a thermally stable composite (TSC), which is resistant to thermal expansion and wrinkle. This structure contributes not but to the outstanding optical functioning of the lens but also to its high rigidity and confidence-inspiring build quality.

Rounded diaphragm

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

High-precision, rugged contumely bayonet mountain

The contumely mount combines high precision with rugged construction. Its treated surfaces and enhanced forcefulness contribute to the exceptional durability of the lens.
