The Fotodiox Mamiya 645 Pro Lens Adapter for Micro Four Thirds Cameras is a high quality adapter that allows you to mount a Mamiya 645 mount lens to a Micro Four Thirds camera body. It features a brass construction with a stainless steel finish as well as the ability to focus to infinity. This works with a leaf spring system for a secure attachment.
This adapter will not allow for electronic control over lens functions. In order to function with automatic metering you will need to place the camera in manual or aperture priority mode, where the camera will utilize stop-down metering to determine the appropriate shutter speed.
