Nikon Z9 vs Sony a9 III
The Nikon Z9 and the Sony a9 III side by side, computed from this guide's catalogue.
Which to pick
Pick the Nikon Z9 if you want more resolution, for cropping and big prints (45.7 against 24.6 MP). Pick the Sony a9 III if you want a newer model (2023 against 2021), which usually means better autofocus and video; more lenses made for it in this guide (278 against 153); and a lighter body (617 g against 1340 g). If you already own Nikon Z or Sony E lenses, the camera on that mount saves you buying them again.
