If you do not want to be fumbling around with the lenses, the best bet is Nikon VR 18-200mm objective, because this allows a full range zoom lens has a wide aspect closely, which is great for shooting landscapes. If you really want to get closeups you need a bigger zoom, and 300-500, however, but the bigger the zoom, the higher the price.
