First wide-angle AF lens with F1.2 maximum aperture for the full-frame Sony E-mount. This lens enables the 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.

Bringing the “Pursuit of Ultimate Image Quality”
To The Next Level With an  F1.2 Art Line Lens for Mirrorless Cameras
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.

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 an F1.2 large-diameter lens is achieved by the large hypersonic 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.

Substantial functions enable user confidence, even in tough environments
The lens features the dust- and splash-proof structure additionally with the water- and oil-repellent coating on the frontmost surface of the lens, which also supports shooting in various environments.

Compatible with Lens Aberration Correction
Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.
Rounded diaphragm (11-blade)
The 11-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

High-speed AF
The HSM (Hyper Sonic Motor) ensures high speed and quiet AF.
High-precision, rugged brass bayonet mount
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

Fast AF with full-time manual focus
Full-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring.

Note: The operation of full-time MF may vary based on mount type.

Hood with lock
Features a hood with a lock to prevent dropping the hood.
