Sigma 35mm f/1.2 DG DN ART Lens for Leica L-Mount - Refurbished by Sigma USA

Bringing The Pursuit Of Ultimate Image Quality To The Next Level
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.

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. 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 & 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.

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.

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.

High-Speed AF
The HSM (Hyper Sonic Motor) ensures high speed and quiet AF.

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

Designed To Minimize Flare & Ghosting
From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as back lighting. SIGMA's Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in back light conditions.

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

Conditions/Easily Meeting The Requirements For Outstanding Lenses
It takes three things to make outstanding lenses. The first is fine design. The second is precise manufacturing. The third is inspection. SIGMA's new lens lines deliver at the highest level on all three counts. First, they are designed to embody concepts that radically redefine the relationship among the photograph, the lens, and the photographer. Third, they are verified using unique performance-evaluation metrics and techniques, developed from the ground up by SIGMA, ensuring the highest level of expressive performance.

Enhancing Lens Performance, Defining 3 Categories
Having taken our lenses to a new level of performance, SIGMA has adopted a simple product identification strategy that makes it easy for the user to identify the kind of lens for which they are looking. Building on this idea, we've reorganized all our lenses into three product lines, each characterized by its own clearly defined concept. From now on, every new lens we develop will be assigned to one of these product lines. This new system is designed to make it easier for users to access the lenses they need.

Customization That Lets The User Do Things Their Way
Based on these new product lines, we have developed special software (SIGMA Optimization Pro) that can update the lens firmware and adjust parameters such as focus . The focus limiter is also customizable for Sports lenses. Using special USB Dock, the user will be able to connect the lens to their PC, and, using easy-to-operate on-screen controls, fine-tune focus and adjust other parameters to suit their personal preferences.
