Is the tamron 28 300mm f 3 5 6 3 di vc pzd good for landscape?

It can work for landscapes, with a caveat. The wide end is 28mm on full frame, which is a sensible starting point for scenery. On APS-C it frames like 42-450mm, so you lose most of the wide view. If you're after big vistas, use it on a full frame body like the Nikon D850 or Canon EOS 6D Mark II.

The f/3.5-6.3 aperture is slow, but landscape work is usually done on a tripod in good light, so that matters less than it would for a fast-moving subject. The landscape guide explains what to prioritise in a camera for this kind of shooting. If you want a wider lens for landscapes, that guide is the place to start.
