Olympus 45mm f/1.8 ED M.Zuiko Digital
(From Olympus lens literature) M.Zuiko Digital ED 45mm ƒ/1.8. This single-focal-length portrait lens has a beautiful shallow depth of field which allows for background blurring effects that are not possible with the 14-42mm kit zoom lens. The Movie-Still-Compatible (MSC) mechanism utilizes nearly “silent” focusing technology. It is great for tracking a moving child or pet, and provides a quick and silent focus mechanism for movies and still photography.
