Sigma 24-70mm f2.8 DG DN (A) Sony-E

The second Art Zoom lens redesigned specifically for mirrorless cameras.

Outstanding results can be achieved with a fast Zoom. With this conviction, SIGMA developed the 14-24mm F2.8 DG DN Art, the first Art-Zoom lens specifically designed for mirrorless cameras and featuring extremely high resolution.

Experience in designing lenses for mirrorless cameras has successfully reduced the size and weight of the lens, while achieving homogeneous and high resolution across the entire focal length range from the center of the image to the edges. In addition, compatibility with the latest mirrorless cameras and their features allows the lens to be used in a wide range of applications, meeting the high demands of professional photographers or ambitious hobbyists alike.

Following in the footsteps of the 14-24mm F2.8 DG DN, the 24-70mm F2.8 DG DN Art is the flagship of the new generation of Art Zoom lenses and the ultimate standard Zoom wide aperture lens.

Best optical performance in its class

The F2.8 Art product line, with its flagship Zoom lenses, was designed primarily to achieve outstanding optical performance.

As ultra-low dispersion glass, this lens incorporates six FLD ("F" Low Dispersion) glass elements and two SLD (Special Low Dispersion) glass elements, taking advantage of an optical design for mirrorless camera lenses. Thanks to the use of three aspherical lenses, this lens effectively reduces aberrations such as longitudinal chromatic aberration or sagittal coma, which are difficult to correct during post-processing. It also delivers homogeneous and superior resolution across the entire focal length range from the center of the image to the edges.

Compatible with the latest full-frame mirrorless cameras

The SIGMA 24-70mm F2.8 DG DN Art is compatible with several models of the latest full-frame mirrorless cameras with L-mount and Sony E-mount. This means that professional photographers or ambitious hobbyists alike can achieve top performance in a wide range of photographic applications.

For example, the AFL button can be assigned different functions via the camera menu, which improves operability during photography. By using a stepper motor with the latest algorithm, a balance between acceleration and smoothness of the AF drive is achieved. This enables stress-free focusing. In addition, this lens is compatible with eye-detection AF commonly used in mirrorless cameras, which enables extremely precise focusing in portrait photography. The Zoom lock mechanism prevents accidental extension of the lens barrel. An AF/MF switch, which many other SIGMA lenses also feature, is also available.

Reflection and ghosting eliminating design

From the beginning of the lens design process, susceptibility to reflections and ghosting is studied to achieve an optical design that is resistant to even strong backlighting. Super Multi-Layer Coating (SML) reduces flare and ghosting and delivers sharp, high-contrast images, even when backlit.

In addition to the Super Multi-Layer Coating, Nano Porous Coating is used. In terms of coating, the lens is designed to be less affected by strong light incidence, such as reflections.

Close focusing distance of 18-38 cm

The closest focusing distance is 18 cm in the wide-angle range. This allows you to get closer to the subject when shooting than the lens hood allows. The largest magnification is 1:2.9 at wide-angle and 1:4.5 at telephoto, allowing for a greater variety of expression in close-up photography.

Round aperture

The near-round aperture consists of 11 aperture blades** and provides a very pleasing bokeh outside the image's plane of focus.

Dust and splash protection

Thanks to its dust- and splash-proof design, the lens is suitable for a wide range of applications and environments.

Brass bayonet

The lens is equipped with a solid and precise brass bayonet. The special treatment of the surface to reinforce the strength enables the long-lasting use.
