i just bought a new D90. pretty excited about it but there is one concern that i have. i bought it for like 1.7k which is the kit set that comes with a 18-55mm lens. the guy told me that nikon comes with 2 kinda sets, and the other one is the one with 18-105mm lens. so im not sure if he is telling me the truth? anyone has any idea if this is true? or did i just get conned?
