With the Nikon FTZ II Mount Adapter, you can use your Nikon F lenses on your Nikon mirrorless camera with Z mount. This is useful if you switch from a Nikon SLR camera to a Nikon mirrorless camera and you still have lenses from your old camera. If you use the FTZ II adapter, all functions of your Nikon F lens work as usual. For example, you can use the autofocus, automatic aperture control, and image stabilization of the F lens. This adapter is dust and splash proof. That means you can use it in different weather conditions. In addition, it has an ergonomic design, which allows you to place your fingers better when taking vertical pictures.
