Sony a9 ii vs sony a7r iv?

The Sony a9 II and Sony a7R IV are both full frame mirrorless cameras from 2019, both with in-body stabilisation and the Sony E mount. The difference is resolution. The a9 II has 24.2 megapixels, and the a7R IV has 61 megapixels. If you want room to crop, large prints, or fine detail in landscapes and studio work, the a7R IV is the one. The a9 II makes less work of each file, so it suits people who shoot a lot and don't need that extra resolution.

Because they share a mount, the lens choice is the same for both. For an everyday kit, I'd start with the Sony FE 24-70mm f/2.8 GM II, then add the Sony FE 70-200mm f/2.8 GM OSS II when you want reach.
