Is the tamron sp 15 30mm f 2 8 di vc usd g2 good for landscape?

Yes, it's a solid wide choice for landscapes. On full frame it covers 15-30mm, which is the range that gives you big skies and strong foregrounds. It's stabilised, and it's made for Canon EF and Nikon F bodies. Read the Tamron SP 15-30mm f/2.8 Di VC USD G2 page for the full list of cameras it fits.

My one caveat is the f/2.8. Landscape shooters usually work between f/8 and f/11, so you won't use that speed much. If you want a lighter, cheaper wide zoom, an f/4 model will do the same job, as the landscape guide explains. For distant ridges and layers of hills, pair it with the Tamron SP 70-200mm f/2.8 Di VC USD G2.
