Price reduced for one week only. TECHART Mount Adapter - Brand: TECHART - Model: Mount Adapter - Color: Black - Package: With original box The TECHART TZM-02 is an electronic mount adapter that allows Leica M-mount lenses to autofocus on Nikon Z-mount cameras. It is equipped with an AF drive motor that automatically moves the lens mount surface back and forth to achieve focus. This product, an improved version of the previous model (TZM-01), features an advanced design with four motors, improving durability and reducing AF operating noise. The bulge for motor storage, which was located at the bottom of the adapter, has been eliminated, resulting in a smart design that is less likely to interfere with camera cases. I am selling it because I sold my Nikon body. I used it for about two days. Thank you for looking.
