Summary: If you are interested in this lens to do 3d video like I was, know that its only for 3d pictures. When the description of the lens states "recording" they mean recording photos. Totally misleading.
Summary: I have confirmation from Olympus America that this lens works with the latest Olympus PEN EP-5 and the Olympus OM-D EM-1. It did not work with prior versions of the PEN EP or EP-L series. I rated neutral because I don't own the lens, merely thinking about buying.
Summary: This allows you to reproduce the capability of a Realist Macro camera cheaply and easily. It has fixed focus so is best used with a classical focus bar - put the camera at that distance and shoot! The factory focus is set at about 25" which is too far for the 10 mm interocular.
