Is the viltrox af 15mm f 1 7 air good for landscape?

Yes, I think the Viltrox AF 15mm f/1.7 Air is a good landscape lens, as long as you shoot on an APS-C body. On Sony E, Fujifilm X or Nikon Z APS-C cameras it frames like 22mm on full frame, which is a useful wide view for big scenes. It has no stabilisation, but landscape work usually happens on a tripod, so that matters less. The f/1.7 speed is more than you need for landscapes, but it doesn't hurt. For the Landscape guide, see Landscape. If you want a zoom that covers more range, see Lenses.
