Olympus Pen F bayonet (half-frame)

An adapter can add distance between lens and film, never remove it. These mounts sit closer to the film than Olympus Pen F bayonet (half-frame), so its lenses can in principle be adapted onto them and still reach infinity. Mounts with no recorded flange distance are left out rather than guessed at.
