AF-S DX Zoom-NIKKOR 17-55mm f/2.8G IF-ED

This high-performance, wide-angle zoom is designed exclusively for use with Nikon’s DX-format, is fast and versatile for travel and portrait work.

Key Features

The world's first constant f/2.8 3.2x zoom lens developed exclusively for use with Nikon's DX-format.
DX design enables a combination of wider angle-of-view with optical characteristics that are optimized for Nikon digital SLR camera sensors.
3 Extra-low Dispersion (ED) glass elements for minimized chromatic aberration providing higher resolution and superior contrast.
Lightweight and compact design (similar to 17-35mm f/2.8 lens).
M/A and M modes allow rapid switching between AF and MF operation.
Rounded diaphragm to make out-of-focus elements appear more natural.
3.2x zoom covers from a wide angle of 79 degrees  and is ideal for architecture, landscape, groups shots and portrait work.
Nikon DX design produces a smaller image circle (the size of the image that is projected by the lens on to the sensor) enabling smaller lens diameter, lighter weight and optimal image quality from center-to edge-to-corner on the image.
3 aspherical lens elements for minimized distortion.
Exclusive Silent Wave Motor (SWM) enables ultra-high-speed auto focusing with exceptional accuracy and powerful super-quiet operation.
Internal Focusing (IF) design for smoother focusing and great body balance.
G-type DX Nikkor is designed exclusively for use with Nikon digital SLR models.
