Nikon 18 70 Dx Views

• Electronics

The AF-S DX Zoom-Nikkor 18-70mm provides a wide-angle to mid-telephoto zoom range in the DX Nikkor series. Designed specifically for use with Nikon digital cameras that feature the smaller DX size chip, this lens features ED (Extra-low Dispersion) glass and Nikon's exclusive built-in SWM (Silent Wave Motor). The lens is targeted at professional and advanced amateur Nikon D-SLR users who demand both the advantages of high optical performance and ultra-wideangle focal range. This G-type Nikkor lens is designed with no aperture rings, and offers easier, virtually mistake-free operation because the aperture does not need to be set to minimum. Equivalent focal length in 35mm terms is 27-105mm.

In terms of focal range, the most basic model in this group test is the Nikkor DX 18-55mm II. Introduced with the Nikon D40 DSLR, this is the cheapest lens on test here and offers a basic 3x optical range. Next up is the Nikkor DX 18-70mm, a popular general-purpose lens which offers a step-up in quality for owners of mid to high-end Nikon DSLRs; ityrs"s the oldest of the four lenses here, but is still a popular bundled option for the D80.

Third in this group test is the Nikkor DX 18-135mm, introduced as the standard kit lens for the Nikon D80, although now also available bundled with other bodies. Finally wetrs"ll look at the Nikkor DX 18-200mm VR, which while not strictly a kit lens, is an enormously popular model which many stores are selling bundled with several Nikon bodies including the D80 and D200.

Each of the four lenses on test most obviously offer steadily increasing focal ranges, which the DX 18-200mm also crowns with Vibration Reduction to combat camera-shake. Beyond this though therelrs"s many differences in build quality, focusing speed and optical performance. In this Nikkor lens group test wesrs"ll closely examine and compare their performance to help you make the right decision for your Nikon DSLR, whether you rs"re upgrading an existing kit lens, or buying a new body and lens combination.
