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

This Sigma 35mm f/1.2 DG DN Art Lens is the first wide-angle AF lens with f/1.2 maximum aperture for the full-frame Leica-L Mount system. It 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.

Construction

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. 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.

Operability

In autofocus photography, comfortable shooting for a f/1.2 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.

Mount

The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

Manual Focus

Full-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring

Rounded Diaphragm

The 11-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

Hood

Features a hood with lock to prevent dropping the hood
