Newer lenses on a "Gothic" Pen F
I recently bought a very nice original meterless "Gothic F" camera, and am having troubles with a lens that worked fine on an FT. The firing cycle doesn't complete- either the diaphragm lever or the meter are being interfered with somehow. If I attempt to fire the shutter and then remove the lens. a slight touch on the aperture closing lever or the mirror allows the mirror to complete its swing and the shutter to fire. There is no obvious drag in the aperture mechanism of the lens, and the shutter fires just fine without a lens mounted. Has anybody out there encountered this problem?
