Question: Does the Sony E-mount also work on the Nikon Z9?
Answer: Yes, with the Techart TZE-01 / TZE-02 adapter, you can use Sony E-mount lenses on the Nikon Z9. The adapter translates the communication between the lens and camera, so autofocus, aperture control, and EXIF data will work in many cases. Important to know: Compatibility may vary depending on the lens model. Autofocus may be slightly slower or less precise with some lenses than on a Sony camera. Functions such as Eye AF or tracking may be limited.
