Nobody expects a zoom with as ambitious of a range as the Nikon AF-S DX Nikkor 18-300mm f/3.5-6.3G ED VR to be an impeccable optical performer. Issues like distortion are readily removed, either in-camera or via software, but there's no fixing a lack of detail.
Long 16.7x zoom range; Optical stabilization; 1:3 macro magnification; Relatively light and compact
Distortion throughout range; Weak edge and telephoto performance; Hood not included
