Do I need a high resolution camera for landscapes?

No, not strictly. Any modern sensor does well at base ISO, and dynamic range (holding detail in bright skies and dark foregrounds) often matters more than raw resolution. Resolution pays off when you print big or crop a lot. What matters for landscape covers the other things to weigh, like weather sealing and a tilting screen.

If you want the resolution anyway:

• Nikon Z7: 45.7 megapixels, and a good used landscape camera.
• Sony a7R V: 61 megapixels, the pick if you crop a lot.
• Leica SL2: 47 megapixels in a weather-sealed body, handy if you shoot in wind and drizzle.
