I am buying the Nikon D90 tonight at Costco. I am simply buying there because if it doesn't work out I can take it back within 90 days. It comes with the 18-105mm DX VR Lens. My question is for anyone in the know or who has the D90 with this lens. The size of the lens is perfect, but I am concerned about the quality of this lens. Is it going to be sufficent for someone looking to make clean, clean, clean, crisp, some-what wide-angle shots in low light? Or am I going to need to get something better?
