Olympus M. Zuiko 45mm F1.8 Interchangeable Lens for Olympus/Panasonic Micro

This single focal length portrait lens has a beautiful shallow depth of field, which enables the background blurring effects not possible with the 14-42mm kit zoom lens. The MSC mechanism is great for tracking a moving child or pet, and provides a quick and silent focus mechanism for movies and still photography.
