Wide angle - 18-55 mm and 55-200 mm lenses required.

Kit lenses are mostly more than enough for generic shoots. Like 18-55 and 55-200/55-250mm are basic kit lenses. If looking for alternative to both lenses, you can get this range in one lens, 18-105/18-135/18-140/24-120. These lenses would be little costly.

If you are looking for basic lens for landscape and normal photography then Nikkor 18-55 mm basic kit lens is the best and for more focus 70-300 mm is pretty good for normal photography

For the basic landscape photography  18 to 55 mm and 55 -250 mm lense is ok .
