This hard wearing bronze adapter ring with built in circuit board allows you to use your M42 lens on your Contax/Yashica Mount camera, saving you the expense of a costly and irreversible conversion.
To use, simply attach the ring to your lens and then the lens to the camera. When you have finished remove both together.
Camera Adapter has no lens element so it does not effect optical performance.
Brand new product, high quality, durable in use.
