The Olympus MCON-P02 Macro Converter screws onto the front of select M.Zuiko Digital lenses and shortens the minimum focusing distance. This allows you to get closer to your subjects and still capture them in clear focus. It includes a 37-46mm step-up ring for compatibility with smaller-diameter lenses as well as front and rear lens caps.
