• Extreme suppression of chromatic aberration and sagittal coma flare

  The Sigma 35mm F1.2 DG II | Art offers even better optical performance than its predecessor, with brilliant clarity throughout the image, even at the fully open F1.2 aperture. The use of SLD glass, highly refractive glass with high anomalous dispersion, and four glass-molded double-sided aspherical elements thoroughly corrects axial chromatic aberration and sagittal coma flare, while significantly reducing the lens size.

• Brilliant sharpness and the large, beautiful bokeh of an F1.2 aperture

  In designing the 35mm F1.2 DG II | Art, Sigma paid special attention to correcting the various optical aberrations that affect image quality. Thanks to these meticulous efforts, the lens delivers brilliant sharpness of the in-focus plane and beautiful bokeh that suppresses color bleeding and double line bokeh. Photographers will appreciate the rich, expressive rendering qualities and the beautiful interplay between the in-focus and out-of-focus areas, especially when shooting wide open at F1.2.

• Designed to minimize focus breathing

  Optimization of the focus group arrangement and aspherical shape significantly suppresses focus breathing. As a result, changes in field of view are effectively suppressed when the focusing distance is changed, making the lens an ideal choice for professional video use.

• Designed to minimize flare and ghosting

  Flare and ghosting, which reduce image quality, are addressed under all conditions of incident light, based on the most advanced simulation technology. High backlight resistance enables clear and sharp images under any lighting conditions.

• Better performance, smaller size and lighter weight thanks to the floating focus system

  The Sigma 35mm F1.2 DG II | Art achieves even better optical performance than its predecessor while being approximately 30% lighter and 20% shorter. A key factor behind this is the adoption of a floating focus design: by allowing the lens groups to move independently of each other, the weight of each lens group has been significantly reduced while simultaneously enhancing optical performance. Additionally, the improved optical design features four aspherical lens elements, high refractive index glass, and thinner lens elements, further contributing to its exceptional performance.

• Fast and quiet autofocusing with dual HLA system

  The dual HLA (High-response Linear Actuator) system drives each of the two focus groups by an individual linear motor. In addition, the use of multiple magnets in each motor allows for a compact focus unit design without sacrificing high thrust. Compared to conventional cam-driven systems, the dual HLA system is not only significantly lighter, but also guarantees fast, reliable and quiet autofocusing.

• A long-lasting, reliable tool for photographic expression

  Manufactured and assembled in Aizu, Japan, using high-precision parts made of aluminum, TSC^*1 and other materials, the 35mm F1.2 DG II | Art is a sophisticated and durable photographic tool designed according to Sigma’s Art line specifications.

  *1. TSC (Thermally Stable Composite) is a type of polycarbonate with a thermal expansion rate similar to that of aluminum. It has a high affinity to metal parts, which contributes to high quality product manufacturing.

• A wealth of shooting assist functions

  The lens features an AFL button that can be assigned a variety of functions on compatible cameras. In addition, the aperture ring can be locked with the dedicated lock switch and changed from clicked to declicked with the dedicated click switch.

• Dust- and splash-resistant structure^*1 and water- and oil-repellent coating

  In addition to a dust- and splash-resistant structure, the front element of the lens features a water- and oil-repellent coating, allowing photographers to shoot without concerns even in harsh outdoor environments.

  *1. The structure is designed to be dust and splash resistant, but not waterproof. Be careful not to bring the lens in contact with a large amount of water. Water inside the lens may cause major damage and even render the lens unrepairable.

• Petal-type hood with locking mechanism

  The Sigma 35mm F1.2 DG II | Art comes with a dedicated petal-type hood that shields the front element from stray light to reduce the chance of unwanted flare. The hood attaches securely to the lens with a locking mechanism.
