Is the voigtl nder apo lanthar 35mm f 2 aspherical good for landscape?
Yes, with a caveat. On full frame it frames as a standard-wide 35mm. That's narrower than the wide zoom the landscape guide calls the classic choice, so it suits scenes with a strong foreground and a modest sky better than huge vistas.
The f/2 aperture matters less here. Landscapes are usually shot between f/8 and f/11, so the speed goes unused, and a tripod handles the slow shutter speeds. Manual focus is fine when the scene isn't moving, but check focus carefully on the screen.
It fits full frame bodies such as the Sony a7R V and the Nikon Z7 II. Check the lens page for the full list.
