Many photographers like to use low ISO sensitivity to keep image noise as low as possible. Especially in star photography, fast wide-angle lenses are often chosen because they can make efficient use of low light. The 14-24mm F2.8 DG DN Art was developed as the ultimate wide-angle Zoom lens by optimizing standard technical specifications for star photography for full-frame mirrorless cameras.

• Part of the newly developed line of high-performance lenses for full-frame mirrorless cameras
• High-resolution image quality through exclusive glass elements with low color dispersion and NPC (Nano Porous Coating)
.
• Extensive feature set ensures user confidence even under difficult conditions
• Rear filter holder as a standard accessory

Uniform

imaging performance and excellent resolution to the edge of the frame make it the "definitive lens for astrophotography." This new-generation Zoomlarge-diameter lens takes advantage of the special features of the short flange focal length, combining a compact body with unprecedented high-resolution image quality.

One FLD glass and five SLD glass elements are arranged to suppress chromatic aberrations right to the edge of the image. Three aspherical lenses, including a large-diameter aspherical lens as the front lens, effectively minimize coma, etc., to achieve stunning resolution. Super multi-layer coating is combined with a newly developed NPC (Nano Porous Coating). The lens is designed to be less susceptible to strong incident light such as backlight.

• SIGMA's new, unique "NPC (Nano Porous Coating)" coating technology incorporates porous silicon dioxide as the coating material. The porous silicon dioxide coating features nano-sized air-filled holes. Holes of this size enable a strong reduction of the refractive index, which can reduce reflection more than with conventional anti-reflective coatings. This greatly reduces reflected light, which causes reflections and ghosting, and achieves clear image quality.

The inclusion of a stepper motor enables fast and quiet AF drive. Shooting is also comfortable with point AF such as face detection/eye detection AF and video shooting. The AFL button, which can be assigned with various functions, extends the working range of the lens.

In addition, the lens features a dustproof and splashproof design, as well as a water- and oil-repellent coating on the front lens, which further supports shooting in various environments
