Olympus MF-1 adapter to use OM-lenses on the E serie camera.

The Olympus MF-1 OM Adapter permits the adaption of certain Olympus OM lenses to be used with the E-1, Evolt E-300, and E-500. When using this adapter, Autofocus (AF) is not available, Stop-down metering is used and Spot metering does not work properly. Although it is possible to use A (aperture priority AE) mode in auto exposure, the aperture display is not available and the aperture display in M (Manual) is not available. In P (Program AE) or S (Shutter speed – priority AE) mode, the shutter releases, but the auto exposure control does not work. The distance scale on the OM system lens may not indicate the actual distance, so users should always use the viewfinder for focusing.
