Sigma 24-70mm f/2.8 DG OS HSM Art Standard Zoom Canon Fit Lens
Sigma 24-70mm f/2.8 DG OS HSM Art Canon Fit Lens Summary
The fourth iteration of this lens from Sigma doesn't disappoint by joining the esteemed ranks of the Sigma Art range of lenses - inheriting the design and build quality the Art lenses have become known for.
Its large diameter and f/2.8 aperture throughout the entire focal range means you can get delightful bokeh whether using it at the wide-end or telephoto-end of the spectrum.
The Hypersonic motor has been redesigned to offer greater torque than previous versions, helping to provide quicker autofocus.

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 lens from Sigma delivers the performance and functionality that help pros succeed in news, nature, and many other fields of photography.
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
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 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.
Bokeh that is a cut above
Sigmaâ€™s first products to feature this technology were the Sigma 12-24mm F4 DG HSM - Art and Sigma 14mm F1.8 DG HSM - Art, which both incorporated a large 80mm aspherical lens as their front lens element.
Building on the success of these predecessors, the Sigma 24-70mm F2.8 DG HSM - Art incorporates an aspherical lens element that helps achieve extremely high resolution. This element is much thicker at the center than the edges, and forming its unusual shape is a feat of manufacturing technology.
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 F2.8 DG HSM - Art to deliver a very natural and smooth bokeh effect, without the visible concentric rings that afflict typical aspherical lens elements.
OS functionality and newly designed HSM for success on any shoot
Lens barrel designed for high rigidity
To this end, the lens barrel contains a large amount of metal, while the external moving parts feature thermally stable composite (TSC), which is resistant to thermal expansion and contraction. This structure contributes not only to the outstanding optical performance of the lens but also to its high rigidity and confidence-inspiring build quality.
Mount with dust- and splash-proof design
