Olympus MF-1 Overview

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.

Does this work with the Panasonic GH4 or GH5?
Asked by: Greg
It should but a lot of functions are not available, with either Olympus or Panasonic cameras, so check out the product description and compatibility info to make sure it does what you need it to do.
