Introduction
De
The AF-S Zoom-Nikkor ED 17-35mm f/2.8D IF 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
Fr
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-
Es
focus images in front of or behind the subject are rendered as pleasing blurs.
