Olympus MF-1 OM Adapter

The Olympus MF-1 OM Adapter allows for certain Olympus OM lenses to be used with Four Thirds Camera Mounts. Autofocus (AF) is not available when using this adapter, and spot metering does not work properly. Stop-down metering is used with the Olympus MF-1 OM adapter.  Although it is possible to use A (aperture priority AE) mode in auto exposure, the aperture display is not available in AE and M modes while using auto exposure. In P (Program AE) or S (Shutter speed - priority AE) mode, the auto exposure control does not work. The distance scale on the OM lens may not display the actual distance, so users should use the viewfinder for focusing.
