Sigma 24-70mm F2.8 DG OS HSM Art Lens – Canon EF Mount

Sigma 24-70mm F2.8 DG OS HSM Art Lens – Canon EF Mount(576954)

The Sigma 24-70mm f2.8 DG OS HSM Art Lens is a versatile wide-angle to portrait-length zoom characterized by its f/2.8 constant maximum aperture. The bright design suits working in available lighting conditions and also affords increased control over depth of field. The optical design incorporates a series of low dispersion and aspherical elements that greatly reduce a variety of aberrations in order to achieve high sharpness, enhanced clarity, and improved colour accuracy. Both Super Multi-Layer and NanoPorous Coatings have also been applied to improve contrast and colour rendering by suppressing lens flare and ghosting when working in strong lighting conditions.

The Performance And Functionality That Pros In All Fields Required

What photographers demand from the 24-70mm F2.8 specification is much more than outstanding image quality. They want all the features that make this a go-to lens for a wide range of photographic opportunities, including optical design ideal for the latest ultra-high-megapixel digital cameras, hypersonic motor (HSM) for high-speed autofocus, optical stabilizer (OS) with powerful stabilization effect, dust- and splash-proof mount with rubber sealing, and a metal barrel for a stable, rigid feel. The Sigma 24-70mm f2.8 DG OS HSM Art Lens delivers the performance and functionality that help pros succeed in news, nature, and many other fields of photography.

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.

SIGMA’s Art Line: A Focus On High Resolution 

To fulfil the uncompromising image quality standard of the Art line, the Sigma 24-70mm f2.8 DG OS HSM Art Lens features a power distribution that has been optimized in exacting detail. This is the lens for those who desire consistent resolution at maximum F2.8 brightness or lower and complete control of the beautiful bokeh effect.

Outstanding Optical Performance

Three SLD glass lens elements and four aspherical lens elements help minimize optical aberrations. To ensure outstanding image quality from the centre to the edges of the photograph, the optical system minimizes coma, which causes points of light to streak, and transverse chromatic aberration, which cannot be corrected by adjusting the aperture. The optical system also minimizes distortion, which can be particularly 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 F2.8 EX DG ASPHERICAL DF, launched in 2001. Representing the fourth generation of the family, the new Sigma 24-70mm f2.8 DG OS HSM Art Lens accomplishes a challenging feat in optical design: incorporating optical stabilizer functionality in a large-diameter standard zoom. By leveraging all of its design and manufacturing expertise, SIGMA has ensured that this new lens fulfils the uncompromising requirements of the Art line for image and build quality.

Bokeh That Is A Cut Above

At wide-open aperture, the Sigma 24-70mm f2.8 DG OS HSM Art Lens offers outstanding photographic expression. The area in focus is extremely sharp, while the background exhibits a beautiful bokeh effect with only slight spherical aberration. Since large-diameter zoom lenses are often used at wide-open aperture, SIGMA has paid close attention to the shape of the bokeh, aiming for perfect circularity.

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.
