Lens is widely used in imaging systems such as a monocular, binoculars, telescope, spotting scope, microscope, and camera (photographic lens). A zoom lens is a mechanical assembly of lenses with the ability to change its focal length manually or through the use of a controller to cover a variety of needs. Camera and lens systems come in a variety of configurations for the consumer, including lens systems attached to the camera and interchangeable lens systems. Cameras with fixed lenses can include point-and-shoot type fixed focal length lenses or zoom lenses of variable focal length. They are easy to use and come in compact packages, but have relatively lower quality optics or limited zoom capability. Interchangeable lenses come in various types. The lenses can include various fixed focal length and zoom ranges. They can include optics of very high quality or less than high quality. Cameras with interchangeable lenses are often known as single lens reflex cameras. A conventional zoom lens of a camera moves two or more lens groups relatively to one another by a cam mechanism arranged within a rotatable cylinder supporting the lens group therein. In recent years, smaller zoom lenses of a high variable magnifying power and of a shorter entire length as a photographing lens are available for use in optical devices such as lens shutter cameras, video cameras and digital cameras. A filter is a square optical glass mounted on a holder accessory, o a glass or plastic disk with a metal or plastic ring frame. It consists of an optical filter that can be inserted in the optical path.
