Sigma has announced their second newly-designed “Art zoom” for mirrorless cameras – the Sigma 24-70mm f2.8 DG DN Art for Sony mirrorless cameras.
Sony is leading the pack in the full-frame mirrorless world so it makes perfect sense for Sigma to be making a native E mount standard zoom with a fast f2.8 aperture. Continuing in the footsteps of the 14-24mm f2.8 DG DN Art, Sigma’s first Art zoom dedicated for mirrorless cameras, the new 24-70mm f2.8 DG DN Art has been designed to give photographers and video creators a real work-horse lens capable of delivering world-class images.
The new Sigma 24-70mm f2.8 Art zoom flagship series offer incredible optical performance due to their sophisticated optical design incorporating extra-low dispersion glass materials, six sheets of “F” low dispersion (FLD) glass and two sheets of special low dispersion (SLD) glass lavishly employed while taking advantage of an optical design dedicated for mirrorless lenses.
By having access to three aspheric lens elements within its optical design, the Sigma 24-70mm f2.8 DG DN Art thoroughly subdues aberrations such as axial chromatic aberration, which is difficult to correct in post, thus achieving uniformity and superior optical performance and corner-to-corner sharpness throughout the zoom range.
In addition to Super Multi-Layer Coating, a Nano Porous Coating is also included.
This lens is designed so as to be less affected by strong incident light such as flare. The mirrorless camera-dedicated design successfully contributes to reduction in the lens size and weight.

The Sigma 24–70mm f/2.8 DG DN Art is fully compatible with the latest Sony full-frame mirrorless camera bodies such as the Sony a7R IV; various functions can be assigned from a camera body, which enhance the operability while photographing.
Employing a stepping motor and the latest algorithm successfully establishes a good balance between acceleration and quietness of the AF drive. This enables stress-free focusing.
Furthermore, this lens is compatible with the Eye-Detection AF used more frequently in mirrorless cameras, which is capable of high-precision focusing at the time of portrait photography. The lack of lens stabilisation shouldn’t be a big deal to Sony mirrorless users, as the camera in-body image stabilisation should take care of most of the unwanted shake in handheld situations.
The lens also offers a minimum focusing distance of 18cm at the wide-angle end, allowing photographers to get much closer to a subject. 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 by close-up photography.
Furthermore, the lens offers a dust-and splash-proof structure and the zoom lock mechanism prevents the lens barrel from extending unexpectedly.
