Is the tokina atx m 11 18mm f 2 8 good for landscape?

Yes, it's a solid pick for landscape on an APS-C body. The landscape guide suggests a wide zoom around 10-24mm on APS-C for big skies and strong foregrounds, and this lens covers that range, roughly 16-27mm full-frame equivalent. It's made for Sony E and Fujifilm X mounts.

The guide also says landscape shooting rarely needs a fast aperture, since you'll usually stop down to f/8 or f/11 anyway. So the f/2.8 here is more than you need, and an f/4 zoom would be lighter and cheaper. It isn't stabilised, but a tripod covers that for landscapes. If you shoot full frame, it works in crop mode, which gives you fewer megapixels, so I'd look elsewhere for a dedicated full-frame wide.
