I shot Konica T cameras for decades and have several legacy lenses in great condition. Any day now, I expect to receive an adapter to use them on my new E-pm1. I am anxious to try this out, and have been researching the use. I understand focusing will be manual and know how to do that with my camera. I surmise I will need to shoot in A mode, setting the camera to the aperture I set the lens at. On one post, I saw a reference to setting the camera to trip the shutter without a lens attached as the camera will not recognize a non-system lens. I cannot find a control in my menu to do this. Can someone help me?
