Our Verdict

Sony α7 III

Nikon D850

The Sony α7 III and the Nikon D850 are suited to different uses. The Sony, being mirrorless, is much more portable and has better overall video features and performance. However, the Nikon is a fantastic option for high-level photography, with a higher-resolution sensor that gives you a bit more room to crop your images. It also has a longer battery life and a more robust build quality. So, if you prioritize speed and portability, get the Sony, but if you want a workhorse and prefer the battery life and optical viewfinder of a DSLR, get the Nikon.
