A versatile medium telephoto prime, the AF NIKKOR 180mm f/2.8D IF-ED from Nikon complements its reach with a bright f/2.8 maximum aperture for working in difficult lighting as well as controlling depth of field. Its optical design incorporates one extra-low dispersion element, which controls chromatic aberrations and color fringing in order to achieve greater clarity and color accuracy. A Super Integrated Coating also helps to improve contrast and color rendering by reducing flare and ghosting. In addition to the optics, this 180mm f/2.8 is also characterized by its internal focusing design for quick and precise autofocus performance.
