Is the nikon af s 28mm f 1 4e ed good for landscape?
Yes, on a full frame body. At 28mm it's a proper wide angle, which is what most landscape work calls for. On an APS-C body it frames like about 42mm, which is too tight for big scenes.
Landscape is slow and often done on a tripod, as the landscape page explains, so the camera matters more than fast autofocus or burst speed. I'd pair this lens with a full frame body such as the Nikon D850 or the Nikon D810. The f/1.4 speed matters less here, because you'll usually stop down for depth. If you want a more flexible wide range, a wide zoom is the better choice, as covered in your first lenses.
