Sigma Art 14-24mm F2.8 DG DN
SigmaSigma Art 14-24mm - Ultimate large-diameter, wide-angle zoom lens optimized for full-frame mirrorless cameras
Sigma Art 14-24mm F2.8 DG DN 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. Particularly in the photography of starry skies, photographers often select bright wide-angle lenses because they can efficiently collect weak light. 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.
High-resolution image quality developed with exclusive low dispersion glass elements and NPC
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.
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. You can assign the AFL button which with various functions to widen 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. Both further support shooting in various environments.
