Sigma 35mm f/1.2 DG DN Art Lens for Full Frame Mirrorless

Sigma 35mm f/1.2 DG DN Art is an ultra-fast semi-wide-angle prime lens for full-frame Sony, Panasonic and Leica mirrorless bodies. The lens, which Sigma claims can resolve over 50 million pixels, contains a total of 17 elements, including aspherical and ‘SLD’ glass. The minimum focus distance is 30cm (~11″), with a max magnification of 0.2x.

The Sigma 35mm f/1.2 is fairly hefty, weighing over 1kg (2.4lbs) with a length of 136mm (5.4″). This is compared to the older 35mm F1.4 Art, which weighs 665g (1.5lb) and measures 94mm (3.7″) in length. The filter ring of the new 35mm F1.2 is supersized too, at 82mm.

The lens has an aperture ring that can be clicked or de-clicked, as well as a customizable AFL button. Build quality appears high, with a weather-sealed enclosure and a coating on the front element to repel oil and water.

The 35mm F1.2 DG DN Art lens will be available later this month, US Price would be around $1,300.

Bringing the “pursuit of ultimate image quality” to the next level with an F1.2 Art line lens for mirrorless cameras

First wide-angle AF lens with F1.2 maximum aperture for the full-frame Sony E-mount and L-Mount system. This lens enables a creation of artwork with astounding resolution and large bokeh effects, such as portraits that make use of a shallow depth of field. It brings the development concept of the Art line “pursuit of ultimate image quality” to the next level. While utilizing optical correction function inside the camera, aberrations that are difficult to post-process are thoroughly corrected thanks to the optical design and it thereby enhances resolution.

About Product Name: Product name includes “DG” when the lens is designed to deliver the ultimate in performance on cameras with full-frame sensors, and “DN” when the lens design is optimized for mirrorless cameras with the short flange focal length.

Key features

  1. Newly developed high-performance lens series for full-frame mirrorless cameras

With mirrorless cameras emerging at an accelerated pace, expectations towards lenses suited for high-performance full-frame mirrorless cameras are growing. Unfortunately, many photographers may feel that they have little choices for mirrorless lens systems in terms of performance, size, extensive lineup, and due to the burden of having to use multiple systems. SIGMA has thus developed and proposes this new full-frame mirrorless lens series as the optimal solution to this challenge.

SIGMA will develop interchangeable lenses with unprecedented specifications and performance by designs that benefit from the short flange focal length feature of mirrorless cameras while retaining the concepts of “Contemporary,” “Art,” and “Sports.” We will announce three models as the first lenses from this series.

  • 45mm F2.8 DG DN | Contemporary

Compact size is realized while maintaining high image quality and is compatible with full-frame mirrorless cameras. This prime lens refines the concept of the Contemporary line.

  • 35mm F1.2 DG DN | Art

The world’s first* 35mm F1.2 as L-Mount and Sony E-mount lens for full-frame mirrorless system. The high image quality of the Art line that pursues ultimate performance is realized by F1.2 maximum aperture.

* As an autofocus lens

  • 14-24mm F2.8 DG DN | Art
  1. Large-diameter, ultra-wide-angle zoom lens for full-frame mirrorless cameras.

While pursuing the ultimate image quality of the Art line, the size is reduced thanks to the exclusive design for mirrorless cameras.

  1. SIGMA’s First F1.2 maximum aperture, large-diameter prime lens

The “Art line in the age of mirrorless cameras” pursues ultimate performance as a large-diameter lens with a focal length of 35mm and also achieves a maximum aperture of F1.2. Three SLD glass elements and three aspherical lenses including a double-sided aspherical lens are optimally arranged in a lens construction of 17 elements in 12 groups. In addition to the optical design that makes use of the characteristic of the short flange focal length, it effectively takes advantage of the correction function inside the camera to correct distortion and peripheral illumination. Various aberrations that are difficult to correct by post-processing, such as sagittal coma flare, are thoroughly corrected by the compilation of the optical design technologies that SIGMA has cultivated, achieving an overwhelming resolution that can resolve over 50 million pixels.

  1. High operability that supports various shooting situations in both still and video

In autofocus photography, comfortable shooting for a F1.2 large-diameter lens is achieved by the large Hyper Sonic Motor (HSM) that gets desired torque required to drive the focus lens group. In manual focus photography, the focus ring driven by the focus-by-wire system with the optimized torque setting responds to fine operations of the photographer. The aperture ring is also mounted with a de-click function for removing clicks, enabling seamless operations that are especially useful during video shooting.

  1. Substantial functions enable user confidence, even in tough environments

The AFL button which can be assigned with various functions widens the range of operations available on the lens. Furthermore, the lens features a dust- and splash-proof structure, along with a water- and oil-repellent coating on the frontmost surface of the lens, which further supports shooting in various environments.
