Nikon 18-200mm AF-S VR DX Lens Review - Introduction

Advances in lens design continue to astound me. This lens, which is designed for DX-format digital SLRs, is a perfect example. Nikon has packed the latest-generation Vibration Reduction, Silent-Wave autofocus, ED glass, and aspheric elements into an 11.1:1 zoom lens of very high optical performance. For Nikon to package all these features into a lens of this caliber, and sell it for $700-750 USD is quite a feat.

As a “DX” lens, it is fully compatible only with digital SLRs: The Nikon D1 and D2 series, Nikon D50, D70, D100 and D200. AF-S (Silent-wave autofocus) is fully functional with these cameras. VR (Vibration Reduction) is functional with all except the Nikon D50 while its built-in speedlight is recharging.

As a “G” lens, it has no aperture ring, but will work correctly on all digital SLRs.

Using the lens on 35mm film bodies will result in significant vignetting of the image, and AF-S, VR, and aperture control will not be possible on several not recent models.

First Impression Upon taking the lens out of the box, the first thing I was struck by is how small this lens is.

The lens is almost identical in size and appearance to the Nikon 24-120mm.

The Tale of the Tape

The construction of this Nikkor lens appears to be similar to that of equivalent lenses offered by third-party manufacturers. All three current lenses (Nikon, Sigma, and Tamron) use some form of low-dispersion/high refractive index glass, and aspherical elements, which help account for the dramatic increase in image quality since the inception of ultra-wide range zooms. The dimensions and close-focus distance of all the lenses are close enough to make the differences insignificant. The Sigma and Tamron are noticeably less expensive, but lack silent-wave autofocus and (most importantly) Vibration Reduction.
