Hi, this is my first time try to using an adapter. I am trying to use Fotodiox adapter to adapted the lens to my Oly E-P2. When I put the lens on the adapter, I turned it until I heard a click sound, and the lens was on the lock position of the adapter. However, the aperture blaze did not move at all stops, it just keeps on the wide open position. I have two Canon FD lens, and both of them behaves the same. Anyone knows why? I am wondering if I did something wrong or the adapter has problem. Thanks a lot!!!
