The day after I ordered the camera I also ordered a cheap K&F converter to use my Nikon lenses on the Olympus... and voila, it works! The first lens I tried was the DX 40mm Micro. At the bottom is a coin.
The aperture ring works but I have no idea how to tell which aperture it is in. Just look at the screen, manual focus, shoot and hope for the best.
Not bad for a hand held shot in bad light.
