Any advice on wide angle lens for Nikon with landscape photos
Fully agree. Sharp, solid and does a decent macro/close up too. For a wider check out the Sigma 10-20mm.If you don't want 'just' wide angle, then you can't go far wrong with a Sigma 17-70. I had one a few years ago before I changed to full-frame.
It's a great little lens.
