The Wimberley P20 quick release plate for lenses is made of silky-smooth andonized aluminum, with anti-twist flanges to trace the edges of the lens' tripod collar. It fits all the Arca-type quick release adapters, which are made by many different companies such as Acratech, Arca-Swiss, Foba, Graf/Studioball, Gitzo, Novoflex, NPC and (of course) Wimberley.
