The Russian lenses are at 12 o'clock. The same results occur with cheapo adapters on an M camera. So it's not the adapters but the lenses. BTW: having the aperture readout at 1:30 position is great with a Hexar and a 35mm Canon lens because you can read the aperture by simply looking through the viewfinder.
