Sigma Announces 14-24mm F2.8 DG DN Art & 35mm F1.2 DN Art for Sony E & Leica L, Introduces 45mm F2.8 DG DN C

From Sigma:
 
Sigma 14-24mm F2.8 DG DN Art
 
Ultimate large-diameter, wide-angle zoom lens optimized for full-frame mirrorless cameras -“The definitive lens for astrophotography” with astonishing resolution.
 
Many photographers like to use low sensitivity shooting to minimize noise as much as they can. Particularly in the photography of starry skies, bright wide-angle lenses are often selected because they can efficiently collect weak light. The 14-24mm F2.8 DG DN | Art has been developed as the ultimate large-diameter, wide-angle zoom lens by optimizing the standard specifications for photographing starry skies for full-frame mirrorless cameras. The uniform rendering performance and outstanding resolution to the edge of the frame make it the “definitive lens for astrophotography.” By utilizing the characteristics of the short flange focal length, this new-generation large-diameter zoom lens combines both compact body and unprecedented high-resolution image quality.
 
About Product Name: Product name includes “DG” when the lens is designed to deliver the ultimate in performance on cameras with full-frame sensors, and “DN” when the lens design is optimized for mirrorless cameras with the short flange focal length.
 
Key features
 
  1. 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 will develop interchangeable lenses with unprecedented specifications and performance by designs that benefit from the short flange focal length feature of mirrorless cameras while retaining the concepts of “Contemporary,” “Art,” and “Sports.”We will announce three models as the first lenses from this series.
    • 45mm F2.8 DG DN | Contemporary - Compact size is realized while maintaining high image quality and is compatible with full-frame mirrorless cameras. This prime lens refines the concept of the Contemporary line.
    • 35mm F1.2 DG DN | Art - The world’s first 35mm F1.2 as L-Mount and Sony E-mount autofocus lens for full-frame mirrorless system. The high image quality of the Art line that pursues ultimate performance is realized by F1.2 maximum aperture.
    • 14-24mm F2.8 DG DN | Art - Large-diameter, ultra-wide-angle zoom lens for full-frame mirrorless cameras. While pursuing the ultimate image quality of the Art line, the size is reduced thanks to the exclusive design for mirrorless cameras.
  2. High-resolution image quality developed with exclusive low dispersion glass elements and NPC (Nano Porous Coating) - One FLD glass and five SLD glass elements are appropriately arranged to suppress chromatic aberration to the edge of the frame. Three aspherical lenses, including a large-diameter aspherical lens at the foremost surface, are used to effectively minimize coma flare, etc., thereby achieving mind-blowing resolution. The super multi-layer coating is combined with a newly developed NPC (Nano Porous Coating). The lens has been designed to be less susceptible to strong incident light such as backlight.
  3. Substantial functions enable user confidence, even in tough environments - Incorporating a stepping motor enables the high speed, quiet AF drive. Shooting is comfortable even in target AF such as Face/Eye Detection AF and during video shooting. The AFL button which can be assigned with various functions widens the range of operations available on the lens. Furthermore, the lens features a dust- and splash-proof structure, along with a water- and oil-repellent coating on the frontmost surface of the lens, which further supports shooting in various environments.
  4. Rear filter holder as a standard accessory - The lens comes with a rear filter holder equipped with a fall prevention lock for attaching sheet type rear filters for shooting starry skies.
Other features
 
  • Full-time manual mode
  • Available Mount Conversion Service
  • Designed to minimize flare and ghosting
  • Evaluation with SIGMA’s own MTF measuring system: A1
  • 11-blade rounded diaphragm
  • High-precision, rugged brass bayonet mount
  • “Made in Japan” craftsmanship

Sigma 35mm f 1.2 DG DN Art Lens

SIGMA 35mm F1.2 DG DN Art
 
Bringing the “pursuit of ultimate image quality” to the next level with an F1.2 Art line lens for mirrorless cameras
 
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.
 
Key features
 
  1. Large-diameter, ultra-wide-angle zoom lens for full-frame mirrorless cameras. - While pursuing the ultimate image quality of the Art line, the size is reduced thanks to the exclusive design for mirrorless cameras.
  2. 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.
  3. 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.
  4. 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 lens. Furthermore, the lens features a dust- and splash-proof structure, along with a water- and oil-repellent coating on the frontmost surface of the lens, which further supports shooting in various environments.
