Which should you buy?

Landscape & Studio / High-Resolution — Z7 II (2020): The Z7 II is a landscape and studio camera first, everything else second. 45.7MP with weather sealing and dual card slots is a compelling package. If you need resolution, it delivers. If you don't, the Z6 II is the smarter buy.
