The definitive large-diameter standard zoom lens for any shoot

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. This all-new 24-70mm F2.8 lens from
SIGMA delivers the performance and functionality that help pros succeed in news, nature, and many other
fields of photography.

【Key features】

1. The large-diameter standard zoom ideal for today’s ultra-high-megapixel digital
cameras

 Outstanding optical performance

Three SLD (Special Low Dispersion) glass lens elements and four aspherical lens elements help
minimize optical aberrations. To ensure outstanding image quality from the center 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 via aperture control, 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
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 fulfills the uncompromising requirements of the Art line for image and
build quality.
