Overview

A wide-angle zoom with remarkable resolution that is perfect for full-frame mirrorless cameras

SPECIAL FEATURESThe 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.”

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 oilrepellent coating on the front-most 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 starryskies.

Designed to minimize flare and 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 backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions.

Fast AF with full-time manual focus

Full-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring.
