I'm often phased by people who think they need a specific lens for landscape photography. Surely it'll vary with the landscape you're stood in front of, what you want to capture and how.
I suppose it depends what you want to achieve. I assume it's not razor thin DoF as that would be a bit niche, so if not just about any lens that's decent when stopped down a bit could come into play if you don't look at the extreme corners. If you do and want something that's excellent across the frame that will whittle down the shortlist. FoV matters and it's a personal choice. My advice therefore is to think what FoV or range you want, create a shortlist and then think about what aperture you'll be using and whittle the shortlist down a little more based on performance at those apertures. Maybe you'll want something that's free of field curvature? Maybe something resistant to flare and ghosting?
Maybe not bother with a new lens and just head out with your 24-70mm, 100mm and 150-500mm and if you know where your going and what sort of picture you want to end up with maybe you'll only take one lens out with you
Good luck deciding.
