An absolutely make loose lens, which is worth every euro. I really appreciate for portrait photography. But still life and architecture simply do with it just fun. It's sharp and contrasty, without having to stop down. Light moods are particularly well captured, a subjective impression on my part. With the help of a slider a mounted filter can be well served, even if the lens hood is attached. A Focusbegrenzer helps faster focusing.
Not only among the Olympus lenses it takes me a top position.
The only drawback: It is quite large and therefore somewhat striking. However perfectly portable.
