Product Overview

  • E-Mount Lens/Full-Frame Format
  • Aperture Range: f/1.2 to f/16
  • Three Aspherical & Three SLD Elements
  • Hyper Sonic Motor AF System
  • Super Multi-Layer Coating and NPC (Nano Porous Coating)
  • Weather-resistant construction with a brass bayonet and water- and oil-repellent lens coatings.

The Sigma AF 35mm f/1.2 DG DN (A) F/ Sony E-Mount features Sigma's first prime lens design with a f/1.2 maximum aperture.

Achieve shallow depth of field as well as extremely selective focus effects with the fast aperture. 
Three low dispersion glass elements and three aspherical elements, including a double-sided element, ensures that spherical aberrations and distortion are effectively controlled for increased sharpness and accurate rendering.

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.

Created for full-frame Sony E-mount mirrorless cameras, this lens features Sigma's first f/1.2 maximum aperture, prime lens design to deliver excellent image quality while optimizing size, as well as weight. It is also suitable for APS-C models where it provides a 53mm equivalent focal length.

Key features

  • Constant f/1.2 maximum aperture is well-suited for working in available light conditions and provides greater control over depth of field.
  • Three Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and color fringing for improved clarity and color accuracy.
  • Three aspherical elements, including a double-sided aspherical lens element, control spherical aberrations and distortion for increased sharpness and accurate rendering.
  • A Super Multi-Layer Coating combined with a Nano Porous Coating has been applied to lens elements in order to minimize lens flare and ghosting to a greater degree than conventional anti-reflective coatings.
  • A stepping AF motor benefits both photographers and videographers with its fast, precise, and near-silent performance. Full-time manual focus control can also be selected.
  • Built-in Autofocus-Lock (AFL) button can be assigned additional functions widens the range of operations available on the lens.
  • Rounded eleven-blade diaphragm contributes to a smooth and pleasing bokeh quality.
  • Weather-resistant construction with a brass bayonet and water- and oil-repellent lens coatings.

High-resolution image quality with exclusive low dispersion glass elements and NPC (Nano Porous Coating)

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. 
Three aspherical lenses, including a large-diameter aspherical lens at the foremost surface, are used to effectively minimize coma flare and achieve mind-blowing resolution. 
The Super Multi-Layer Coating is combined with a newly developed NPC (Nano Porous Coating). The lens has been designed to be less susceptible to strong incident light such as backlight.

  • SIGMA’s new unique coating technology "NPC (Nano Porous Coating)" incorporates porous silica as the coating material. The porous silica layer has nano-sized holes with air inside. 
    Having holes of this size enables a large reduction in the refractive index, allowing the reflectance to be lowered more than conventional anti-reflective coatings. 
    As a result, reflected light causing flares and ghosting is sharply reduced, achieving clear image quality.
  • The 11-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
  • Compatible with Lens Aberration Correction for in-camera corrections of peripheral illumination, chromatic aberrations, distortion etc.

Construction

  • HSM (Hyper Sonic Motor) ensures high speed and quiet AF.
  • AFL button can be assigned with various functions to widen the range of operations available on the lens.
  • The aperture ring is also mounted with a de-click function for removing clicks by the Click ON/OFF Switch, enabling seamless operations that are especially useful such as during video shooting.
  • The lens features a dust- and splash-proof structure, along with a water- and oil-repellent coating on the frontmost surface of the lens.
  • High-precision, rugged brass bayonet mount.
