The dream of any landscape photographer is to go out and catch the essence of all of his or her surroundings, preferably in one image. So we go “wider” and wider. Wide-angle lenses are getting more abundant in the photography closet and we are never happy with the lenses we have.
When I had a Nikon D7100, the widest lens I had was a Sigma 10-20mm. It looked great, it was a good lens until it encountered a rocky path. The next was a Tamron 11-16mm. It is still very good, but “not as wide”.
