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.
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.
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 by the Click ON/OFF Switch, enabling seamless operations that are especially useful such as during video shooting. Furthermore, the AFL button(②) which can be assigned with various functions widens the range of operations available on the lens.
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.
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.
The 11-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
The HSM (Hyper Sonic Motor) ensures high speed and quiet AF.
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
Full-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring.
Features a hood with lock to prevent dropping the hood.
Our new lineup fully expresses our approach to lenses and photography itself. All of our lenses belong to one of three lines—Contemporary, Art, or Sports—all of which share our development philosophy and advanced manufacturing system. High performance, high quality, and high end in every respect, these lenses give people who love photography lasting value and consistent, exciting results. The secret is our passion for craftsmanship that we put into every production process and every product. All of SIGMA lenses are made in Japan specifically in Aizu.
