This wide aperture single-focal-length lens delivers crystal-clear images with sharpness throughout the image area. This lens is ideal for capturing everything from indoor shots to powerful scenic photos. To ensure clear imaging performance even under unfavourable conditions such as when shooting against the light, the lens surfaces are coated with ZERO Coating, minimising issues with ghosts and flares. This metal-bodied premium lens has a consistent look with the OLYMPUS PEN series camera. The Movie-Still-Compatible (MSC) mechanism provides a quick and silent focus mechanism for movies and still photography.
