These adaptors allow full range focus to infinity. They mount to the FD camera body using the breech lock ring rather than the later twist bayonet fitting. They are fully compatible with both types. Full manual metering is available, but in stop down mode. This means that the viewfinder image darkens as the aperture is reduced.
