There isn't one best lens for landscape. Of course, you can use a 50mm, or wider, or telephoto, or zoom, depending on what you are trying to achieve...the perspective and field of view you are looking for. Here is a good You Tube video that shows how different FL can be used for landscapes and how perspective and field of view can significantly change the image.
