DESC: Designed to be a one-lens solution and weighing in at a scant 19.9 ounces and measuring only 3.8 inches in length, this lens provides an extraordinary (35mm equivalent) picture angle of 27-300mm when mounted on any Nikon DX-format camera such as the new D300s cameras. Additionally, the optical formula contains two ED glass elements and three aspherical lenses to minimize chromatic aberration and distortion. The resulting images exhibit extreme sharpness, extraordinarily vibrant color and crisp contrast.
