Nikon FTZ is an adapter that allows you to use older Nikon F-mount (DSLR) lenses with the new Nikon Z-series mirrorless cameras. It is an extremely useful accessory for saving money, as it allows you to avoid buying new lenses when switching to the Z system. Compatibility and Performance Full Support (AF/AE): Works with AF-S, AF-P, and AF-I type lenses. Manual Focus Only (MF): Older AF-D type lenses (which rely on the camera's internal "screwdriver" motor) will not have autofocus because the adapter does not have its own motor. Image Quality: The adapter is a hollow tube without glass elements, so image quality is not degraded. Stabilization: If the lens has VR (vibration reduction), it will work in conjunction with the camera body's stabilization.
