The Nikon D850 and the Nikon Z9 are both formidable cameras from different eras. The D850 is arguably the best general-purpose DSLR ever made, whereas the Nikon Z9 is Nikon’s first mirrorless flagship, combining the high resolution of the D850 and the speed of a camera like the Nikon D6 (with some mirrorless magic thrown in). If you’re a current D850 owner or are deciding on your first high-end Nikon camera, there’s a good chance you might be choosing between these two amazing cameras. If so, here’s how they stack up.

Summary and Recommendations
Both the D850 and the Z9 are certainly impressive, but it’s clear that the Z9 comes out ahead in almost every way except weight and viewfinder battery life. D850 users upgrading to a Z9 will find plenty of new features to like, even in areas where the D850 already excelled (like autofocus and buffer). In fact, going from a D850 to a Z9 is like upgrading to a high-resolution D6 with all the enhancements mirrorless has to offer. Unless you’re allergic to electronic viewfinders, you will almost certainly find the Z9 to be the better camera.
The Z9 also presents significantly upgraded video capabilities. Most previous Nikon DSLRs do not have a great video, and there is no possibility of using the viewfinder on a DSLR when recording video. The video codecs and framerates are much better on the Z9, too.
That said, in real-world performance, the Nikon D850 can still keep up in many situations. Although it doesn’t have the ridiculously deep buffer or the 20 FPS of the Z9, for all but the most difficult situations, the D850 can still nail excellent photos of difficult subjects like birds in flight and almost any other genre of photography. Having tested both cameras side-by-side, the actual image quality is extremely similar – ISO performance, dynamic range, and detail are comparable on both cameras, so pure image quality is not a smart reason to pick the Z9 over the D850.
If you’re considering buying either of these cameras for the first time rather than upgrading, the D850 is also more compact and lighter than the Z9. Considering the D850 can be bought fairly cheaply used these days, it is an excellent option for more budget-conscious shooters.
Personally, as a wildlife photographer, I would go for the Z9 these days, especially because of the electronic-only shutter, and because I enjoy taking wildlife video. But, as amazing as the Z9 is, a used D850 and some F-mount lenses will already be more than what a typical professional requires. So, you can comfortably get either camera without a problem, even though the Z9 is newer and has some more advanced features.
