Verdict
Regarding some glowing reviews available on the web the expectation were rather high. Unfortunately the (tested sample of the) Nikkor AF-S 18-200mm f/3.5-5.6 G IF-ED VR II DX wasn't able to convince completely. Weak points are rather hefty distortions and high vignetting (@ f/3.5) at 18mm.
Apart from a few weak spots the resolution figures are quite good though and it is possible to get very decent images from this lens under field conditions. The VR can surely help to save the day in situations where similar zooms must fail utterly The build quality is a little soso for a lens in this price class and probably the biggest disappointment.
All in all the Nikkor is a highly interesting lens but not without flaws (hardly surprising for a 11x zoom).
