The quality of the adapter is OK The price is customary juicy as at Olympus. However, there is the function and use of the Olympus EM to say 5 good stuff. I have of my e -5 f the 50: 2 macro 12-60 and 50-200. All of these lenses can use the contrast autofocus camera not good umgehen.Dh they pump forever until they have found a sharp adjustment. I use if only because of the weight only 50 macro and only for macro shooting with manual focus. Because eternal pumps charged the battery enormously. So if all the features of Olympus are advertised, so that can be seen with limitations, because in practice it will be apart from macro shots with the cumbersome focusing little joy haben.Deshalb I subtract one point.
