Metal mount adapter for attaching Nikon F-mount lenses to Micro Four Thirds cameras. - Brand: Kernel - Model: NIK-M4/3 - Type: Mount Adapter - Compatibility: For Nikon lenses - Material: Metal - Color: Black - I tried attaching a lens to it once or twice. There are no electronic contacts, so it will be manual focus. There are no scratches and it's almost like new. Thank you for looking.
