Sigma 12-24mm f/4 DG HSM Art Lens (Nikon F)

Description Product Description Everything photographers require of an ultra-wide-angle zoom—and more.When it comes to ultra-wide-angle lenses, photographers require outstanding image quality from the centre of the image to the edges without any distortion. Such performance is particularly valuable in architectural photography. The new SIGMA 12-24mm F4 DG HSM | Art leverages SIGMA’s accumulated expertise in the processing and manufacture of aspherical lenses and incorporates multiple aspherical lenses produced with precision glass moulding. The lens also features lens elements made with FLD (“F” Low Dispersion) glass, which is equivalent to fluorite in performance, and an optimized power distribution. Together, these features help minimize distortion, transverse chromatic aberration, and coma flare. As a result, image quality is outstanding across the image, all the way to the edges.The SIGMA 12-24mm F4 DG HSM | Art features an 80mm large-diameter moulded glass aspherical lens—the largest such element in this class of lens. This lens is highly effective in minimizing distortion, spherical aberration, and coma flare.With F4 throughout the zoom range, this lens is one stop brighter than conventional lenses. Photographers can now use a higher shutter speed that will crisply capture leaves fluttering in the breeze and other quick-moving subjects. A constant aperture during zooming also makes this lens exceptionally easy to use.With a minimum focusing distance of 24cm at the 24mm end of the zoom range, photographers can compose close-up shots with impressively expansive backgrounds.The newly designed Hyper Sonic Motor (HSM) is large, offers 1.3 times the torque of its predecessor. Even at low speeds, it offers exceptionally stable performance.
