Sigma announces Ultimate large-diameter, wide-angle zoom lens optimized for full-frame mirrorless cameras

by Dhiram Shah

The Sigma 14-24mm F2.8 DG DN Art lens 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.


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.

The 11-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image. The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens. The Sigma 14-24mm F2.8 DG DN Art lens weighs 795g / 28.0oz. The kind of quality for which SIGMA is perpetually striving can be summed up by two adjectives: “essential” and “optimal”.
