the subject is DA lenses, which neither your nikon nor your sigma lens are. DA lenses have a spring loaded aperture lever and no aperture ring, so they stay stopped down all the way when not connected to a camera.
Mea culpa, mea culpa, mea maxima culpa. This unworthy one can never hope to achieve forgiveness for being incorrect upon this subject.
