Best lens for D800 for maximum sharpness?

Focal length to cover landscapes, probably a wide angle to mid range zoom.

If the zoom feature is your thought..I'd have to agree with the others and say either the 24-70mm, although the 24-120mm F4 is darn close, I have to keep putting on my 24-70 just to check then scratch my head in wonder, or the 14-24mm although the same goes with the 16-35mm, it's a head scratcher too, I sold mine and kept the 14-24mm but constantly go through the "maybe I shouldn't have sold it"...scratch scratch...lol
