It is easy to carry around this compact, lightweight single focal-length lens. It is ideal for taking photographs of your family and pets. The bright F1.8 aperture makes it possible for anyone to shoot pictures emphasising the subject, and applying beautiful defocusing effects to the background. To ensure clear imaging performance even under unfavourable conditions such as when shooting against the light, the lens surfaces are coated with ZERO coating, which minimises issues with ghosts and flares. The Movie-Still-Compatible (MSC) mechanism provides a fast and silent focus mechanism for movies and still photography.
