Nikon 18-70mm f/3.5-4.5 G IF ED AF-S DX
This lens was Nikon's first “normal” zoom designed specifically for the DX format. It was introduced in February 2004 as an entry level “kit” lens for the Nikon D70.
Optically this is not a bad lens. The construction is quite complex, with 15 elements in 13 groups, with one aspheric, and three ED elements. Sharpness is good. Distortions are well controlled for such a low-cost zoom. Flare, ghosting and CA is well under control. Its weak spot is vignetting, which is very visible wide open and does not go away until you stop down to f/8.
In terms of build quality, it is far better than most “kit” lenses. It looks and feels well made and it comes with a metal mount and a lens hood. It also has a ring SWM that provides fast and silent auto-focus with instant manual override.
