The Nikon Z8 is a mirrorless camera in the same high resolution class as the Nikon D850, but it adds modern autofocus, an electronic viewfinder and far more video capability. If your D850 still does everything you need, there is no rush to change; if you shoot action, wildlife or video, the Z8 offers clear advantages.
What each camera is for
The D850 is a DSLR with an optical viewfinder, strong battery life and a deep catalog of F mount lenses. It is a dependable choice for landscape, studio and travel photographers.
The Z8 is a more advanced body with a flagship-level feature set in a body smaller than a pro DSLR. It targets people who need fast subject tracking, high frame rates and serious video options, while keeping a resolution class similar to the D850.

Check Nikon’s own pages for current details before you make a decision.
Reasons to upgrade
- You miss shots because focus tracking cannot keep up with birds, sports or children running.
- You want serious video features without carrying a second camera.
- You like seeing exposure changes live in the viewfinder.
- You want a body that can fit smaller bags.
Reasons to keep the D850
- Your results already meet your needs, and your technique is the limit rather than the camera.
- You prefer an optical viewfinder and long battery life.
- You own many F mount lenses and do not want to adapt them.
- You would rather spend on lenses, lighting or travel than a new body.
Moving your lenses
Nikon sells an adapter that lets many F mount lenses work on Z bodies. Most modern AF-S lenses work well with it, but older designs may focus more slowly or not at all in autofocus mode. Look up each lens on the maker’s compatibility list before you rely on it.
Size, weight and daily carrying
The Z8 is smaller than a typical pro DSLR, but it is not a tiny camera. With a large lens it still feels like serious gear. The D850 is also a substantial body, so the weight gap is modest. Mirrorless bodies usually get fewer shots per battery charge, so plan for spare batteries on long shoots.
FAQ
Will my D850 batteries work on the Z8?
Battery types differ between models, so do not assume they are shared. Confirm on the maker’s page.
Is the Z8 only for professionals?
No. Enthusiasts use it as well, though its feature set is aimed at people who need its speed and video tools.
The Short Version
Choose the Z8 if tracking, video and a modern viewfinder matter to you, and choose to keep the D850 if your lenses and results already satisfy you. A new body helps most when the old one is limiting your shots.
