Olympus Adapter MF-1 [MFT – OM-lens]

You can stop down using the lens aperture ring on all Olympus OM-lenses with a aperture control ring.
Works with Panasonic/Olympus MFT cameras:
Ex:
Panasonic GH1, GH2, GF1, GF2 og GF3
Olympus PEN E-P1/P2/PL1/PL2/P3/PL3/PM1

A fixed tab in the adapter is used to hold the aperture actuator in the closed position.

When the lens is mounted, the aperture ring will control the aperture and you will use stop-down metering.
Make sure you purchase an adapter that has this tab. Some third part adapters don’t.

Not all lenses meter accurately at all f-stops.

In manual exposure mode you can see the actual exposure in the viewfinder and compensate accordingly.
Use PEN camera in manual [M] or aperture [A] control mode.

Unlike a DSLR the EVF can gain up to compensate for the stopped down lens so unless you're shooting in low light the viewfinder image will be nice and bright, and live view zoom 3x-5x-7x-14x is great for accurate focusing.

The metering is working perfectly but the camera only works properly when in A or M mode.

Olympus Pen’s support image stabilisation [in the camera body] with legacy lenses, just dial the focal length in on the cameras IS settings.

Use Creative mode [M] [A] or [P] [S]

[START OK] [IS<x>] [INFO] dial inn <focal length>mm.

Do not take into account the 2x magnification factor applied in the Four Thirds system; enter the actual focal length of the lens being used. If the attached lens has a focal length that is not shown on the chart, please select the closest value.
