Sigma announces 35mm F1.2 Art series lens for mirrorless cameras


Sigma’s new 35mm F1.2 DG DN Art is the first full-frame Art series lens with an F1.2 maximum aperture intended for Sony E-mount and L-mount bodies. According to Sigma, the new 17-element lens has high optical correction with only distortion and vignetting correction applied in-camera. Both mount types will come with an aperture ring that can be de-clicked for video capture. 

It will be available in July, 2019 with an SRP of £1,459.99 (inc VAT), $1499.

More information can be found at Sigma’s Global Vision site.

The new lens can be pre-ordered form the following stores:

Take your mirrorless to the next level

― Benefit from the finest performance that the SIGMA’s first F1.2 large aperture prime delivers 

  1. Newly developed high-performance lens series for full-frame mirrorless cameras
  2. SIGMA’s First F1.2 maximum aperture, large-diameter prime lens
  3. High operability that supports various shooting situations in both still and video
  4. Substantial functions enable user confidence, even in tough environments

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.

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.

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.

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.
