The Nikon AF Zoom-Nikkor 80-200mm f/2.8D ED Telephoto Zoom Lens covers portrait to medium-length telephoto focal lengths. This lens is a flexible & fast zoom that is fit for portraiture & event shooting. Its constant f/2.8 maximum aperture makes it suitable for working in low-light conditions, while helping it aid in achieving selective focus & shallow depth of field effects. Its optical design includes three extra-low dispersion elements, which help to prevent color fringing & chromatic aberrations for increased clarity, & its Super Integrated Coating helps to reduce flare & ghosting. The lens's internal focusing AF system provides you with precise & quick control, and its manual focus adjustment is available as well. A rounded nine-blade diaphragm provides a smooth bokeh quality for shallow depth of field imagery.
