Is the sony vario tessar t fe 24 70mm f 4 za oss good for landscape?
Yes, it's a sensible landscape lens. The landscape guide says standard zooms around 24-70mm cover most scenes, and f/4 zooms are a good fit because you'll usually shoot at f/8 to f/11 anyway. This one is also stabilised and fits a wide range of full frame Sony bodies.
Its 24mm wide end is less dramatic than the 16-35mm the guide calls the classic landscape lens for big skies and strong foregrounds. If you shoot a lot of wide scenes, I'd pair it with the Sony Vario-Tessar T* FE 16-35mm f/4 ZA OSS. For the reasoning, see Landscape.
