Sigma 15mm F1.4 DG DN Diagonal Fisheye Art Lens

Sigma 15mm f/1.4 DG DN Art Fisheye Overview Boasting an expansive 180° angle of view and an ultra-fast f/1.4 maximum aperture, the Sony E-mount Sigma 15mm f/1.4 Fisheye DG DN Art Lens is a diagonal fisheye that brings epic scope and sweeping clarity to astrophotography, architecture, and landscape photography. With a minimum focusing distance of 15.2″ and high-speed autofocus, the lens also yields dramatic yet intimate images when used in action and sports applications. Body & Optical Design With 21 lens elements in total arranged in 15 groups, including four FLD elements, three SLD elements, and two aspherical elements, the lens construction optimizes the reproduction of bright points of light. It also means the lens is sharp across the entirety of its viewing angle. The two rear sheet filter slots and the included Arca-Swiss compatible tripod collar benefit the long exposures necessary for astrophotography. The lens is also designed to handle all conditions of incident light, including high backlight resistance, to consistently promote clarity, sharpness, and overall image quality.
