The 500mm f/4 DG OS HSM Lens takes its spot as the flagship in the speedy Sports line. Available here with a Nikon F mount, this super telephoto lens lets you capture distant subjects, and with a speedy Hyper Sonic AF motor users will be able to easily track fast action. A relatively fast maximum aperture of f/4 furthers your imaging potential with excellent illumination for a lens of this class. One SLD and two FLD elements help ensure outstanding optical performance by minimizing aberrations and distortion while a Super Multi-Layer coating combats flare and ghosting. Also, this lens is equipped with an Optical Stabilizer system that compensates for up to 4 stops of shutter speed. It is protected from dust and water and uses a brass bayonet mount. Filter users will appreciate a 46mm drop-in filter system while a rotating tripod collar is available for using the lens on a tripod or monopod. Additionally, the 500mm lens is fully compatible with Sigma's Global Vision teleconverter for getting an extended reach. This super telephoto 500mm f/4 prime lens is designed for full-frame format Nikon F-mount cameras, and can also be used with APS-C models where it will provide a 750mm equivalent focal length. One SLD and two FLD elements have been incorporated within the lens design to correct for chromatic aberrations throughout the entire focusing range and help to ensure high image sharpness, clarity, and contrast regardless of focus point or aperture setting. This optical design also helps to control distortion and limit vignetting. The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. A dedicated switch on the barrel of the lens provides multiple AF modes, including a focus recall setting and AF off. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time. Two manual focus modes are available, the standard AF/MF option and an MO setting that switches the lens into manual even during continuous AFSpecialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates.
