AF-S DX NIKKOR 18-140mm f/3.5-5.6G ED VR
Key Features
- DX-format compatible, high-power approx. 7.8x normal zoom lens covering a focal-length range from 18 to 140 mm (angle of view is equivalent to that of a lens with a focal length of 27 to 210 mm in FX/35mm format)
- High optical performance is realized with the employment of one ED glass element and one aspherical lens element
- VR (Vibration Reduction) minimizes camera shake by offering a shutter speed equivalent to 4.0 stops* faster
- *Based on CIPA Standard. This value is achieved when attached to a DX-format digital SLR camera, with zoom set at the maximum telephoto position.
 
- Silent Wave Motor (SWM) is incorporated to ensure quiet AF operation
