|AF-S||The lens is equipped with ultrasonic motor to provide very fast and virtually silent autofocus. Learn more|
|DX||The lens is designed only for Nikon APS-C digital SLR cameras.|
|E||The lens is equipped with electromagnetic aperture control and provides very accurate and fast exposure which is very important in continuous autofocus mode.|
|ED||The lens incorporates low dispersion elements to minimize chromatic aberrations and ensure excellent sharpness and contrast even at maximum aperture.|
|VR||The lens is equipped with optical image stabilizer. The stabilizer allows to increase the shutter speed by several stops and shoot handheld in such lighting conditions and at such focal lengths where without stabilizer you will have to use tripod, decrease the shutter speed and/or increase the ISO setting which can lead to blurry and noisy images.|

Design and Features
The lens barrel is of moderate weight, made of high-quality plastic. The lens mount is metallic.
This is the first Nikon DX lens to feature an electromagnetic diaphragm; this innovation electronically adjusts the aperture within the lens, resulting in consistent exposure during high speed shooting.
The lens features M/A - M focus mode switch.
|M/A||Autofocus mode that allows switching to manual focus with virtually no time lag - even during autofocus servo operation and regardless of autofocus mode in use.|
|M||Manual focus mode.|
The lens uses front filters with standard size of 72 mm which are easy to find. However, filters of such size are more expensive and mainly used with professional lenses.
The filter thread does not rotate during focusing which allows convenient use of different types of filters (including but not limited to polarizing and gradient).
A fluorine coating has been applied to the outer surfaces of the front and rear lens elements to repel particles of dust, water or oil drops for easier cleaning of the lens surfaces.
The lens features optical image stabilizer, which, according to the manufacturer, compensates up to 4 stops of shutter speed. Theoretically it allows to capture sharp images of static subjects at shutter speeds down to 1/5 second at focal length of 80 mm*).
*) without the need to increase ISO sensitivity and/or use a tripod, at the same lighting conditions and at the same aperture
At the choice of the photographer the image stabilizer can operate in one of the following modes:
|VR NORMAL||Corrects vertical and horizontal camera shake. Automatically detects panning and then corrects camera shake only in one direction.|
|VR ACTIVE||Corrects vertical and horizontal camera shake when shooting from a moving vehicle, or some other unstable position. Panning is not detected.|
It is often thought that image blur caused by camera shake can be prevented by using a tripod. Actually, however, even using a tripod may result in image blur because of tripod vibration caused by mirror or shutter movement at the time of exposure. The image stabilizer automatically differentiates the frequency of the vibration from that of camera shake, and changes algorithm to correct image blur caused by slight tripod vibration.
The closest equivalent of this lens is Sigma 17-70mm F/2.8-4 DC Macro OS HSM | C which has similar range of focal lengths, the same speed, optical image stabilizer, focuses closer and costs twice less.
