The Nikkor AF-S 18-70mm f/3.5-4.5 G IF-ED DX is considered as THE standard zoom for Nikon DSLRs thanks to attractive specifications combined with a moderate price tag of around 350 US$/€. Nikon also sells this lens in some camera kits (D70s, D200).
The Nikkor is a designated DX lens projecting a reduced image circle and as such not compatible to full-frame SLRs. The field-of-view is equivalent to 27-105mm (3.8x zoom ratio) on classic full frame cameras.

The build quality is very decent. Nikon used higher quality plastics compared to e.g. the AF-S 18-55mm DX but it can't match the (excessively higher priced) AF-S 17-55mm f/2.8 DX here. Interestingly the lens features a dust and waterproof rubber sealing mount which is highly unusual in this price class. The zoom ring has a relatively high friction whereas the focus ring feels quite smooth (though a little plasticy). As you can observe in the product shot above the lens has a duo-cam zooming mechanism which extends towards the long end of the zoom range. The inner lens tubes/cams wobble only marginally. A petal-shaped hood (not shown) is also part of the standard package. Typical for all G lenses the Nikkor does not provide a dedicated aperture ring anymore. The Nikkor features an AF-S motor (silent-wave (ultrasonic)) which is both very fast and near silent. It is also possible to intervene manually in S-AF mode. Thanks to an IF (internal focusing) design the front element does not rotate so using a polarizer remains easily possible.
