Sigma 24-70mm f/2.8 DG OS HSM Art Series Lens - Sigma
The technical details behind this lens
Sigma 24-70mm f/2.8 DG OS HSM Art Series Lens - Sigma offers great optical performance. The optical design features three Special Low Dispersion (SLD) elements that markedly reduce chromatic aberrations and colour fringing throughout the zoom range for enhanced clarity and colour accuracy. The four aspherical elements control spherical aberrations and distortion for improved sharpness and accurate rendering. Offering a Super Multi-Layer Coating, this feature has been applied to lens elements in order to minimise lens flare and ghost effects and contribute to producing contrast-rich and colour-neutral imagery, even in backlit conditions. This lens also features a constant f/2.8 maximum aperture that is well-suited for working in available lighting situations and delivers greater control over depth of field when using shallow depth of field techniques. The Integrated Hyper Sonic Motor (HSM) realizes quick and quiet autofocus, which is further complemented by an optimized AF algorithm to achieve smoother focusing performance. The Hyper Sonic Motor allows full-time manual focus control simply by rotating the focus ring.

Our expert's opinion
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 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 F2.8 DG HSM OS Art is handcrafted at our single factory in Aizu, Japan, and undergoes individual evaluation before leaving Sigma’s facility.
