The Pro Lens Mount Adapter for Contax G-Mount Lens to Canon EF-M Mount Camera from FotodioX allows a Contax G-mount lens to be used with a Canon EF-M mount camera. It is designed to support focusing to infinity, and is constructed from brass and an aluminum alloy along with a stainless-steel lens mounting ring to provide a durable, yet lightweight camera-to-lens connection.

This adapter does not support electronic communication between an attached camera and lens. After being placed on the front of the adapter, aperture control on a compatible lens would continue to be used. For focus control, the Pro Lens Mount Adapter features a manual-focus ring that extends and retracts a compatible lens in a manner similar to a Contax G-mount camera.
