Sigma’s workhorse 24-70mm f/2.8 Art lens is getting a refresh — for mirrorless cameras. This is the second newly-designed Art zoom lens from Sigma and follows on from the 14-24mm F2.8 DG DN (Digital Native) Art zoom.
It’ll be available at launch for the E-mount by Sony and the L-mount by the Leica/Panasonic/Sigma L-Mount Alliance.

Sigma’s Art line is the company’s flagship series designed for high-end optical performance — and the company says the new 24-70mm Art is no exception. Because of the bright aperture and versatile zoom, the 24-70mm f/2.8 is a popular lens choice among professional street photographers.
Sigma says the new 24-70mm f/2.8 offers the best optical performance of its class thanks to a sophisticated optical design that delivers high resolution throughout the entire zoom range.

“By employing three aspheric lenses, this zoom lens thoroughly subdues aberrations such as axial chromatic aberration or sagittal coma aberrations, which are difficult to correct in post-processing, tailors the resolution and achieves uniformity and superior optical performance from the center to the periphery throughout the zoom range,” Sigma says.

By employing three aspheric lenses, this zoom lens is claimed to thoroughly subdue aberrations such as axial chromatic aberration or sagittal coma aberrations, which are difficult to correct in post-processing. The lens is also said to achieve uniformity and superior optical performance from the center to the periphery throughout the zoom range. In addition to Super Multi-Layer Coating, Sigma’s proprietary “Nano Porous Coating” is employed to achieve high-contrast and clear image quality. This lens is designed to be less affected by strong incident light such as flare.

The maximum magnifications are 1:2.9 at the wide-angle end and 1:4.5 at the telephoto end, which provides a wider range of expression for close-up photography. The minimum focusing distance is 18 cm at the wide-angle end.

While the lens builds on the success of the Sigma 24-70 f/2.8 DG OS HSM, the earlier lens was made for Nikon, Canon, and Sigma mounts. Sigma redesigned the lens for mirrorless, which reduces the lens’ size and weight.
The lens is now more than six ounces lighter, weighing in at just under 30 ounces.

Build-wise, the lens is both dust and splash-proof, and there’s a zoom lock switch on the body to prevent the lens barrel from extending when you don’t want it to.

The Sigma 24-70mm f/2.8 DG DN Art will be available in L-mount and Sony E-mount in mid-November. Pricing will be announced at a later date.
