Sigma 24-70mm f/2.8 DG OS HSM Art Lens for Canon EF

Top-Level Performance Optimised for the Era of Ultra-High-Megapixel Cameras

The Sigma 24-70mm f/2.8 DG HSM OS Art is a premium workhorse zoom lens designed for the latest high-megapixel DSLRs. A constant aperture of f/2.8 through the zoom range make this a highly versatile tool and a brand new Optical Stabilisation (OS) system help compensate for camera shake. Though a common focal length, the Sigma 24-70mm Art brings a new level of usability and durability featuring a rugged metal barrel and an emphasis on image quality. Building off the experience from the 12-24mm Art, the aspherical elements used in the 24-70mm f/2.8 OS Art undergo a highly precise level of polishing producing elements thicker in the centre than on the edges. This process creates stunning image quality and beautiful circular bokeh. Like each and every Global Vision Lens, the Sigma 24-70mm f/2.8 DG HSM OS Art is handcrafted at our single factory in Aizu, Japan and undergoes individual evaluation before leaving Sigma’s facility.

Landscapes to Portraits, All with Exceptional Optical Quality

Three SLD (Special Low Dispersion) glass lens elements and four aspherical lens elements help minimise optical aberrations. To ensure outstanding image quality from the centre to the edges of the photograph, the optical system minimises coma, which causes points of light to streak, and transverse chromatic aberration, which cannot be corrected via aperture control, The optical system also minimises distortion, which can be particularly evident in wide-angle shots, resulting in excellent optical performance throughout the zoom range.

Capture Beautiful Portrait Photographs with a Bokeh that is a Cut Above

At wide-open aperture, this 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. 

OS Functionality and Newly Designed HSM for Success on any Shoot

Designed for advanced utility in a wide variety of situations, the optical stabiliser (OS) offers a powerful stabilisation effect. The newly designed large hypersonic motor (HSM) offers 1.3 times the torque of its predecessor and exceptionally stable performance even at lower speeds.

Lens Barrel Designed for high Rigidity

Since large-diameter standard zoom lenses tend to serve as a go-to lens and see frequent use, the SIGMA 24-70mm f/2.8 DG HSM | Art is designed to stand up to the challenging shooting environments that pros encounter. 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.

Shoot in any Weather with a Dust- & Splash-proof Mount Design

Since the area of the lens most vulnerable to dust and other foreign bodies is the mount, rubber sealing helps provide peace of mind. In addition, the front lens element features a water- and oil-repellent coating that helps the lens perform well in the rain, near water, and in other challenging conditions.
