SHOTEN Mount Adapter LM-CR II (Leica M mount lens → Canon RF mount conversion) I am selling this as I stopped using it after only a few uses. The LM-CR II from SHOTEN, the original brand of Focus Camera, is an improved version of the old "LM-CR". The knurling (anti-slip) on the side of the adapter has been shaped to fit the fingers, improving the grip and hold compared to the old model, making it easier to handle. The lens lock button has also been improved, allowing for smooth pushing and comfortable lens removal. Features: Mount conversion, Weight: Approximately 60g
