For landscape, architecture and travel photograpy, I currently have the Nikon non-VR 24-70mm f/2.8 and use it with my D850. Do I really need a lens with focal lengths below 24mm or should I upgrade my 24-70mm to VR? I've been looking at the Nikon 17-35mm f/2.8 but half that range is already covered by my 24-70mm, so I'm only adding 17-23mm to my current capabilities. Do I really need those focal lengths? I don't think I'm interested in really wide angle shots, but who knows. I know Nikon has the 12-24mm as well.
