The M.ZUIKO DIGITAL ED 75 - 300mm F4.8 - 6.7 lens is a super telephoto zoom that boasts a focal length range equivalent to 150 - 600mm on a 35mm camera. Previous lenses offering 35mm equivalent focal lengths of 600mm or more were invariably large, heavy, making it difficult for most users to enjoy the benefits of super telephoto shooting. The M.ZUIKO DIGITAL ED 75 - 300mm F4.8 - 6.7, however, takes advantage of the Micro Four Thirds System's high mobility to bring these benefits to a wide range of users. Also this lens offer quieter and more responsive AF performance, and offer SLR image quality for still-image and movie shooting. When mounted on an OLYMPUS PEN camera, the lenses support the camera body's built-in image stabilization system and offer effective shake compensation at all focal lengths. The inner focusing mechanism uses a light, compact, single-element unit to enable exceptionally fast, quiet autofocusing for smooth, stress-free still-image and movie shooting.
