There is no question it is a great lens. The reviewers have compared it to the Nikon AF 85mm f1.4D which I do have. Here's a quick shot using the Nikon lens at f1.4 on the E-M5. I don't have a live model but I do have a lot of different plants outside in my yard. It was raining for this shot so the colors are nice and saturated. This branch is in the outer center of the bush with more branches behind it which are nicely blurred. I like this lens on this body.
