Featuring a brand new OS and highly efficient and fast AF system, the revamped 24-70mm F2.8 Art embodies all the technical qualities and finesse that define the high-performance Sigma Global Vision Art series. Covering a wide range of shooting scenarios, the 24-70mm workhorse DNA includes three SLD (Special Low Dispersion) glass elements and four aspherical elements to reduce chromatic aberration. The 24-70mm F2.8 Art aspherical elements use Sigma's groundbreaking thicker center glass design and highly precise polishing process, delivering stunning images and bokeh effects. The lens' purpose-built structure boasts a new metal barrel for optimal durability with TSC composite internal moving components designed to resist thermal contraction and expansion.
The Sigma 24-70mm F2.8 DG HSM OS Art is a premium workhorse zoom lens designed for the latest high megapixel DSLRs. A constant aperture of 2.8 through the zoom range makes this a highly versatile tool and a brand new Optical Stabilization (OS) system helps 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 F2.8 OS Art undergo a highly precise level of polishing, producing elements thicker in the center then on the edges. This process creates stunning image quality and beautiful circular bokeh. Like each and every Global Vision Lens, the Sigma 24-70mm F2.8 DG HSM OS Art is handcrafted at our single factory in Aizu, Japan and undergoes individual evaluation before leaving Sigma's facility.
