I have no idea what you're talking about, Dario. Is it maybe a stop DOWN screw? I seem to remember some early m4/3 adapters having a screw (as opposed to a ring) to stop down lenses, although I think it was only for rangefinder lenses with short registration distances (and thus very thin adapters).
If you plan on using DA lenses, buy an adapter like the Novoflex that has a (blue) stop-down ring. If using FA or earlier lenses, just buy the cheapest adapter you can find (which won't have a stop-down ring).
