Here we are comparing two cameras with different body types: Sony A7R III, which was introduced in October 2017 is a Pro Mirrorless camera with a 42.0MP Full frame sensor whereas Nikon D850, which was introduced in August 2017 is a Advanced DSLR camera with a 46.0MP Full frame sensor. There is only 2 months difference between A7R III and D850 so we are expecting this to be a fair comparison regarding age and technology level.
Despite some fundamental differences of these two body types, Mirrorless cameras are becoming serious alternatives to DSLR cameras thanks to their size/weight advantages and recent improvements in their focus speeds , which makes this comparison even more interesting. Fortunately, you can't go wrong with any of these cameras as we rank them amongst Top 10 cameras in their classes. Sony A7R III is ranked #7
out of 56 Pro Mirrorless cameras with an overall score of 94 whereas Nikon D850 is ranked #1
out of 93 Advanced DSLR cameras with an overall score of 88.
