INSTRUCTIONS

Fit the Four Thirds Adapter into the camera’s lens mount by aligning the 

lens attachment marks and turn  it in the direction of the arrow until it 
locks into position.

To  remove the Four Thirds Adapter, turn the lens in the opposite 
direction while pressing down the lens release button.

Attach an Olympus OM system lens.

Autofocus (AF) is not available.

Stop-down metering is used. Spot metering mode does not work properly.

Although it is possible to use the A (aperture-priority AE) mode in auto 
exposure, the aperture display is not available.

The aperture display is not available in M (Manual) exposure.

In the 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. Always use the viewfinder for focusing.

For recommended lenses, focal lengths and aperture (F-number) ranges, 
see the OM system compatibility on the right.
For inquiries, contact your nearest Olympus dealer.
