Dpreview picked the Nikon Z7 II as the “Best camera for landscape photography in 2021” because of the camera’s combination of size, price, ergonomics, and image quality:
“The Nikon Z7 II sits in a class of cameras that are all excellent for landscape photography. For us, though, the Nikon’s ISO 64 setting, which allows it to capture 2/3EV more light than most of its peers, gives it an edge in terms of image quality. The additional light gives improved tonal quality in addition to its excellent dynamic range.” (via Dpreview)
The four years old Nikon D850 camera is also on the recommended list.
