Depending on how wide you really want to go,the Tokina 16-28 2.8 FX is a heck of a bang for the buck and even more DX choices.

I am referring to cropped sensor cameras versus FX full frame large sensor.

It can be, but a superwide is a very specialized lens. I find superwides over-extend the perspective, and getting a natural looking landscape is difficult. I use them for close quarter shooting mostly. When I want a natural perspective I use a longer lens - in DX I would use anything from 24mm to 90mm. If i need to take in a wider scene, then I rotate the camera and take a series of 50% overlapping images to later stitch into a panorama in post processing. If you think about it, the landscape masters - the guys that used brushes and watercolor or ink, pastels, etc - had nothing but their eyes to visualize a landscape - for a wider view they merely turned their heads. No such thing as ultrawide lenses back then. So it all depends on what you are after. If you are OK with background objects looking like they are 100 mi away, and stuff in the foreground looming unnaturally large - then the superwide is a good solution for you. Otherwise, a longer lens and stitched panos will almost always give you better results.

For the record, I use FX, and have a 14-24, 24-70, 80-200, 24 PC-E, 45 PC-E and 85 PC-E. I find that the lenses I use most for landscapes are the 45 and the 85. The 14-24 is my least used lens.

The Nikon 10-20 is my vacation and go to lens along with the Nikon 18-200 lens. I used the 10-20 in Arizona at the Antelope Canyon and it was great on my D500 camera. Yes, it would work for landscape but watch if your shooting anything close up, ie. like five feet away. Converging lines which can be taken care of in post processing or do what I do and adjust the Perspective Control Options on my D500, this will also automatically correct it. Don't ask me about it, you can look it up in the instruction booklet that comes with your Nikon.

Assuming you're looking for a DX lens, I'm very pleased with my Tamron 10-24 f/3.5-4.5 on my Nikon D7100.
