Hans, by "release" I am assuming you mean that when you press the shutter button, you get a shot. True?

If it is set to "on" then the camera will release, when a lens is set to manual aperture (aperture ring not in A mode, which is always the case for M/K lenses) otherwise the camera will not release. Note: When the aperture ring is not in A mode, the lens will be always wide open during exposure.
