Sigma 35mm f1.2 DG DN Art Lens – Leica L Mount

The Sigma 35mm f1.2 DG DN Art 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.

Features of the Sigma 35mm f1.2 DG DN Art Lens

• Full-time manual mode
• Hood with lock
• Available Mount Conversion Service
• Designed to minimize flare and ghosting
• Evaluation with SIGMA’s own MTF measuring system: A1
• 11-blade rounded diaphragm

Newly developed high-performance lens series for full-frame mirrorless cameras

With mirrorless cameras emerging at an accelerated pace, expectations towards lenses suited for high-performance full-frame mirrorless cameras are growing. Unfortunately, many photographers may feel that they have little choices for mirrorless lens systems in terms of performance, size, extensive lineup, and due to the burden of having to use multiple systems. Sigma has thus developed and proposes this new full-frame mirrorless lens series as the optimal solution to this challenge.

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.

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 Sigma 35mm f1.2 DG DN Art Lens. Furthermore, the lens features a dust- and splash-proof structure, along with a water- and oil-repellent coating on the front-most surface of the lens, which further supports shooting in various environments.
