Positioned as a workhorse lens among Leica L-mount full-frame mirrorless systems, the Sigma 24-70mm f/2.8 DG DN Art is a versatile wide-angle to portrait-length zoom characterized by its f/2.8 constant maximum aperture. The bright design suits working in available lighting conditions and also affords increased control over depth of field. The optical design incorporates a series of low dispersion and aspherical elements that greatly reduce a variety of aberrations in order to achieve high sharpness, enhanced clarity, and improved color accuracy. Both Super Multi-Layer and Nano Porous Coatings have also been applied to improve contrast and color rendering by suppressing lens flare and ghosting when working in strong lighting conditions.

Features:
  • L-Mount Lens/Full-Frame Format
  • Aperture Range: f/2.8 to f/22
  • Six FLD Elements, Two SLD Elements
  • Three Aspherical Elements
  • Super Multi-Layer & Nano Porous Coatings
  • Stepping Motor AF System
  • Rounded 11-Blade Diaphragm

 

Best-in-class optical performance

The F2.8 Art zoom flagship zoom lens series is developed primarily to achieve superior optical performance.

As extra-low dispersion glass materials, six sheets of “F” low dispersion (FLD) glass and two sheets of special low dispersion (SLD) glass are lavishly employed while taking advantage of an optical design dedicated for mirrorless lenses. 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.

In addition to Super Multi-Layer Coating, Nano Porous Coating* is employed. 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.

* In the SIGMA’s own proprietary coating technology, NPC (Nano Porous Coating), porous silica is employed for coating materials. A porous silica layer creates Nano-sized pores inside which air is contained. The pores of this size make it possible to reduce the refractive index significantly, even lower compared with the existing antireflection coatings, thereby drastically reducing reflected light causing flare and ghosting and achieving the high-contrast and clear image quality.

Ensuring compatibility with the latest full-frame mirrorless camera bodies

The SIGMA 24–70mm F2.8 DG DN ensures compatibility with various types of the latest full-framemirrorless camera bodies tailored for L-Mount and Sony E-Mount so as to be capable of exerting the best performance under any photographic circumstances, assuming that professional or advanced amateur photographers use it.

To the AFL button, for example, 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.

Adaptable to various uses and photographic environments

The minimum focusing distance is 18 cm at the wide-angle end. This allows you to come closer to a subject than the end of a hood to take photographs. 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 adapts to various uses and usage environments through employment of the dust- and splash-proof structure and the zoom lock mechanism for preventing the lens barrel from extending unexpectedly, and meet a wide range of needs for photography. An AF/MF switch used for the many conventional SIGMA’s lenses is also embedded in the lens barrel. Essential and basic functions are also equipped.
