Is the tokina f rin 20mm f 2 fe af good for landscape?

Yes, I think it's a good pick for landscape on full frame. At 20mm it's wide enough for big scenes, and it works on any Sony E full frame body in the list, including the Sony a7R V if you want plenty of resolution for detail.

Landscape is slow, and you'll usually be on a tripod, so the lens's lack of stabilisation matters less here than it would for handheld shooting. f/2 is brighter than most landscape work needs, but it's handy for dusk and blue hour.

On APS-C it frames like 30mm, which is much less wide, so I'd only use it for landscapes on a full frame body. For the wider picture of what to look for, see landscape.
