Sigma 35mm f/1.2 DG DN Art Lens for Leica L

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.

SIGMA is pleased to announce the launch of the Art line prime lens lineup for full-frame cameras in L-Mount. These L-Mount series lenses have achieved high-speed AF and are fully compatible with AF-C mode, in-camera image stabilization, and in-camera aberration correction.

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 by the Click ON/OFF Switch, enabling seamless operations that are especially useful such as during video shooting. Furthermore, the AFL button which can be assigned with various functions widens the range of operations available on the lens.

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.

Features

Optimized AF for L-Mount
With the AF drive control program and high-speed communication tuned for each lens, shooting at speed with high-precision AF control is achieved. The lenses also support the AF-C mode.

Compatible with in-camera image stabilization
Compatible with in-camera image stabilization, the camera automatically detects the focal length of each lens and optimizes image stabilization performance.

Data pre-loaded for compatibility with in-camera aberration correction
Fully compatible with in-camera aberration correction (corrections for peripheral illumination, chromatic aberrations, and distortion). By matching corrections to the optical characteristics of the lens, this function takes image quality to an even higher level.

Native mount for a more rigid and stable feel
Making the lens mount native provides a much more rigid and stable feel to the lens than using an adapter. Featuring a surface treatment to enhance strength, the brass bayonet mount offers a high-precision fit and exceptional durability. The mount connection area incorporates rubber sealing for dust- and splash-proof construction.

Available SIGMA Mount Conversion Service
This service converts specifications of the mount of SIGMA lenses to that of a different camera body. Users can "tailor" their favorite lenses to the camera body if they plan to get a new one in the future. This allows continued use of their favorite lenses over the long term regardless of the camera system.
