Sigma 14-24mm F2.8 DG DN Art is a wide-angle zoom with remarkable resolution that is perfect for full-frame mirrorless cameras.
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.
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.
SIGMA’s unique coating technology Nano Porous Coating
The super multi-layer coating is combined with SIGMA’s unique "NPC (Nano Porous Coating)" technology. The lens has been designed to be less susceptible to strong incident light such as backlight.
"NPC (Nano Porous Coating)" incorporates porous silica as the coating material. This 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.
Integrated Rear Filter Holder
The lens comes with a rear filter holder equipped with a fall prevention lock for attaching sheet type rear filters and resin filters from third party manufacturers. Perfect for use with neutral density filters when shooting landscapes or video
