Introduction
The AF-S Zoom-Nikkor 17-35mm f/2.8D IF-ED employs a Silent Wave Motor
inside the lens to drive the focusing mechanism, thus the "S" designation. As a
result, autofocusing is smooth, silent, and almost instantaneous. In addition,
this lens features internal focusing (IF), so there is no change in the overall
length of the lens from infinity to its closest focusing distance of 0.28m (0.9 ft),
contributing to balanced hand-held operation. Moreover, three aspherical and
two ED (Extra-low Dispersion) lens elements ensure that images that are sharp
and clear from center to edges and virtually free of color fringing, regardless of
the focal length setting. Also, by utilizing a 9-bladed diaphragm that produces a
nearly circular aperture, out-of-focus images in front of or behind the subject are
rendered as pleasing blurs.
Note: This lens offers Silent Wave autofocusing with Nikon F6, F5, F4-Series,
F100, F90X/N90s*, F90-Series/N90*, F80-Series/N80-Series*,

cameras, in addition to Nikon digital SLR cameras, such as the
D3-Series and D300-Series.
