Sigma to add 14-24mm F2.8 DG DN Art of full-frame mirrorless

Sigma is adding a new ultra-wide 14-24mm F2.8 lens to its Art series for full-frame mirrorless cameras. the 14-24mm DG DN Art. It will be available in Sony E-mount and Leica/Panasonic L-mount versions. The optical design is similar to the existing 14-24mm F2.8 DG HSM Art for DSLRs, but it’s not identical. That model uses a 17-element design with three FLD (fluorite-like) elements and two SLD-type elements. The new 18-element design utilises five SLD and one FLD and three aspherical including the large diameter first element. The position of the remaining two has not yet been disclosed.

The new lens is sealed and features a rear filter holder. It weighs 795g (28 ounces). It is expected in August 2019, with a price of £1459.99 (inc VAT) or $1499 USD. More information can be found at Sigma’s Global Vision site.

The new lens can be pre-ordered from the following stores:

Astonishing starry skies at hand
―A wide-angle zoom with remarkable resolution that is perfect for full-frame mirrorless cameras

  1. Newly developed high-performance lens series for full-frame mirrorless cameras
  2. High-resolution image quality developed with exclusive low-dispersion glass elements and NPC (Nano Porous Coating)
  3. Substantial functions enable user confidence, even in tough environments
  4. Rear filter holder as a standard accessory

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.

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.
* SIGMA’s new unique coating technology “NPC (Nano Porous Coating)” incorporates porous silica as the coating material. The porous silica layer has nano-sized holes with air inside. Having holes of this size enables a large reduction in the refractive index, allowing the reflectance to be lowered more than conventional anti-reflective coatings. As a result, reflected light causing flares and ghosting is sharply reduced, achieving clear image quality.

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.

 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.
