Nikon's AF-S DX Nikkor 18-105mm f/3.5-5.6G ED VR lens is a welcome addition to the Nikon DX-format DSLR systems, and an ideal counterpart to the D90 DSLR. This versatile optic offers much of the benefits of the enormously-popular 18-200mm VR lens but in a lighter, smaller body that takes a smaller filter as well.
The AF-S Silent Wave Motor in the 18-105mm VR yields speedy, silent, on-the-money AF performance with fulltime manual focus override. In particular, the AF-S motor keeps up with skittish, erratic subjects that overwhelm normal camera-driven-motor AF systems.
