Key Features

Fast, wide-angle to medium Telephoto AF-S zoom lens optimized for edge-to-edge sharpness on both the Nikon FX (23.9 x 36mm) and DX format image sensors.
Three Extra-low Dispersion (ED) elements and PGM aspherical lenses control chromatic aberrations while enhancing sharpness and contrast, even at the widest aperture settings.
Nikon's Silent Wave Motor (SWM) enables ultra high-speed auto focusing with exceptional accuracy and powerful, super-quiet operation.
Focus as close as 14.9 inches.
M/A focus mode switch enables quick response to changing situations between manual and auto focus operation.
Enhanced optical formulas engineered to produce exceptional sharpness, contrast and color, rendering outstanding image integrity.
Exclusive Nano Crystal Coat further reduces ghosting and flare for even greater image clarity.
Internal Focus (IF) provides fast and quiet auto focusing without changing the length of the lens, retaining subject-working distance through the focus range.
Rugged construction with professional-grade dust and moisture resistance.
