Over the years, SIGMA has created a variety of bright prime lenses. Various Features In Sigma AF14-24 F2.8 DG DN Lens This is in addition to a water-, oil-, and scratch-resistant coating on the frontmost lens surface, which allows for shooting in different environments. The lens can have multiple functions assigned to it, which expands the scope of operation. The quiet, high-speed AF drive can be achieved by incorporating a stepping motor.Įven in target AF, such as Face/Eye Detection AF, and while video shooting, it is easy to shoot comfortably. Clear images are achieved by reducing ghosting and flares caused by reflected light. It also lowers reflectance more than traditional anti-reflective coatings. This allows for a significant reduction in refractive index. The pores of the silica layer have tiny holes that contain air. "NPC" (Nano Porous Coating), uses porous silica to cover the substrate. SIGMA Nano Porous Coating is a unique coating technology This lens is less sensitive to intense incident light, such as backlight. SIGMA's exclusive coating technology, "NPC" (Nano Porous Coating), is used to combine the super multi-layer coating with the NPC (Nano Porous Coating). To achieve mind-blowing resolution, three aspherical lenses are used, including one large-diameter aspherical Lens at the foremost. ![]() Five SLD glass elements and one FLD glass are properly arranged to prevent chromatic aberration at the frame's edge. Sony Sigma 14-24mm f/2.8 DG DN at Alanphoto is for Sony E-mount mirrorless cameras that offer stunning images with a wide variety of focal lengths. ![]() Sony: Sigma Camera Lenses AF14-24 F2.8 DG DN | Alan Photo Additionally, a built-in lens hood serves to protect the front element as well as prevent stray light from causing flare. A built-in Autofocus-Lock (AFL) button can be assigned additional functions to widen the range of operations available on the lens, while inside, a rounded 11-blade diaphragm improves image quality by helping to create smooth bokeh. Though full-time manual focus is available, this lens is equipped with a stepping motor that enables smooth, high-speed autofocusing that is notably quiet whether utilizing features such as Face/Eye Detection AF or during video shooting. This helps to more effectively produce color-accuracy and contrast-rich imagery in a variety of lighting conditions. A Super Multi-Layer Coating combined with a Nano Porous Coating also helps to suppress lens flare and ghosting to a greater degree than conventional anti-reflective coatings. Featuring a sophisticated optical design, a series of low dispersion and aspherical elements is used to minimize both chromatic and spherical aberrations throughout the zoom range in order to achieve high sharpness, clarity, and color accuracy. ![]() Created for full-frame Sony E-mount mirrorless cameras, the Sigma 14-24mm f/2.8 DG DN Art Lens provides a versatile range of wide-angle focal lengths with excellent image quality while optimizing size and weight.Īn Art-series zoom, this lens is also distinguished by its fast f/2.8 constant maximum aperture to suit working in available lighting conditions.
